About the SmartWay Technology Program

EPA's SmartWay Technology program develops test protocols, reviews strategies and verifies the performance of vehicles, technologies and equipment that have the potential to reduce greenhouse gases and other air pollutants from freight transport. The program establishes credible performance criteria and reviews test data to ensure that vehicles, equipment and technologies will help fleets improve their efficiency and reduce emissions.

New! Updated SmartWay-designated Trailer and SmartWay-verified aerodynamic technology programs. EPA is expanding these programs to include refrigerated trailers, more testing options, improved protocols, and the new “Elite” level. Visit the “Aerodynamics” tab and “Tractors/Trailers” tab below for more details.”

SmartWay verifies technologies based on measured fuel savings and/or other criteria described herein. EPA does not guarantee any performance or claims by the manufacturer, and the described performance is only applicable when the technology is installed and used in accordance criteria described herein. While EPA may request related information, verification is not an indication of endorsement, safety, regulatory, compliance or other performance consumers should consider. Manufacturers, installers, and consumers must comply with all applicable local, state, and federal safety regulations.

SmartWay now verifies aerodynamic devices and device combinations for the following fuel savings categories:

1% (1%-3.9% fuel savings)
4% (4%-4.9% fuel savings)
5% (5%-8.9% fuel savings)
9% (9% and higher fuel savings)

The table below shows the currently verified SmartWay Trailer Devices and Device combinations for 53’ Box and refrigerated trailers. Please be advised that not all technologies are appropriate for all trailer types (i.e. gap reducers and combinations that include gap reducers would not appropriate for refrigerated trailers).

Currently SmartWay Verified Aerodynamic Devices Table

The old SmartWay verified list has been replaced by the table below. The devices are listed first by level of fuel savings and then by device type. Each subsequent column represents a method of verification testing; if a device was tested with a particular method and met the fuel savings criteria (i.e. 9% for an elite combination), then it will receive a check mark "✓" in that test column.

After a device has been verified with one test method, EPA SmartWay encourages the manufacturer to conduct additional testing using one or more additional methods. For the Elite and 5% categories, if the fuel savings from those tests are no less than 1% of the category verification level (i.e. a verified elite combination got 8.0% fuel savings on an optional secondary test method), SmartWay will give the device a "*" for that test method. Click here to learn more about the meaning of "✓" and "*" in the Aero Device Table (XLS) (21K).

(Note: All older verified devices have a check mark “✓” in the “Smartway Verification Pre-2014” column, meaning that they were tested using pre-2014 protocols).

EPA encourages fleet owners and operators to consider this table when making technology choice(s) for trailers.

Aerodynamic Device Manufacturers: How to Get Listed with SmartWay?

The SmartWay Verification Program evaluates the performance of trailer devices to reduce drag and improve fuel economy for Class 8 tractor-trailers. This is to help trucking fleets and owner/operators find the best ways to improve gas mileage.

Considerations before applying for verification listing:

Manufacturers must communicate with EPA before conducting testing for verification purposes (this does not apply to R&D testing). EPA cannot not accept test data from an unapproved test program, no exceptions.
Regulatory Requirements: Some technologies may not qualify for verification as the product may have regulatory requirements that supersede verification.
Availability: The technology submitted for verification must be commercially available for installation. No products still in the research and development stage will be verified.
Health Effects and Safety: Concerns with health effects or safety may need to be addressed prior to EPA review of a technology for verification.

Verification Process

Apply for Verification: To begin, manufacturers must first complete Part 1 of the application (PDF) (5 pp, 567K, EPA-420-F-12-023, May 2012) and submit it to Tech_Center@epa.gov. EPA uses the Part 1 application as an initial review of the verification request. If the technology or strategy is within the scope of SmartWay verification, EPA will follow up with the Part 2 application requesting technology details for review.
Application Acceptance: Once the manufacturer has submitted the two-part application and addressed all follow-up questions from EPA, the application will be accepted.
Verification Testing: Manufacturers can choose one or more of the following testing methodologies for verification (you must choose at least ONE).
- SAEJ 1321 Track Test (2012) Coming Soon!
- Wind Tunnel Test Procedure (2014) Coming Soon!
- Coast Down Testing (2014) Coming Soon!
Submit Approvable Test Plan: The manufacturer must have EPA approval prior to scheduling verification testing.
Test Information and Results: Once testing is complete, the manufacturer must work with the testing facility to put together a complete test report. Once EPA receives the report, the data will be reviewed to ensure that the device performance is suitable for verification.
Notice of Verification Letter: If the test data shows the device to be eligible for verification, EPA will issue a formal Verification Letter. Sample Verification Letter (PDF) (2 pp, 458K, March 2012)
Verified Technologies List: Once the technology has been verified, EPA will add it to Aerodynamic Devices Table as show above and CARB will be notified. The list describes the technology and other information contained in the Verification Letter so that potential customers may determine if they wish to purchase the technology. The SmartWay Verified Technologies Communication Guidelines (PDF) (5 pp, 183K, February 2010) provide information on communicating your organization's involvement in the U.S. EPA SmartWay Transport Partnership.
Verified Technologies and Changes: Products sold as verified technologies must be produced and installed as described to EPA. If a manufacturer changes a verified technology or implements changes relative to information provided to EPA, the manufacturer must update the documentation with the Verification Program. If EPA determines the changes may impact performance or the changed technology may not be represented by the original verification, EPA may require further testing or conclude the changed product requires a separate verification.

Verified Low Rolling Resistance Tires

EPA demonstrated that certain low rolling resistance tires can reduce NOx emissions and fuel use of long haul class 8 tractor-trailers by 3 percent or more, relative to the other popular high rolling resistance tires. These improvements are achieved when:

Tires are used on the axle positions for which verification is specified.
Verified low rolling resistance tires are installed on all axle positions of the tractor and trailer. (Note: EPA has also demonstrated incremental fuel savings when low rolling resistance are used just on the tractor and/or just on the trailer.)
All tires must be properly inflated according to the manufacturer's specifications.

MULTI-POSITION TIRE APPLICATIONS AND USE WITH 6x2 TRACTORS:

Tire manufacturers specify the intended axle position(s) for tires, and EPA’s verified list indicates tires that achieve rolling resistance target values for those axle positions. Tires verified for the trailer axle position meet the rolling resistance target for steer and drive axles, and if the tire performance characteristics are acceptable, the manufacturer may specify use for those applications. Similarly, verified steer tires meet the rolling resistance target for the drive axle, and if the tire performance characteristics are acceptable, the manufacturer may specify the use for the drive axle position. Consequently, verified steer and trailer tires are acceptable for use on the tag (undriven) axle of 6X2 tractors if the tire manufacturer confirms the performance is acceptable that application. Fleets should check with the tire manufacturer of such multi-position tires to confirm that the tire is suitable for the intended application. For SmartWay designated tractors, which require verified low rolling resistance tires, equipped with 6x2 drivetrains, verified steer or trailer tires may be used on the tag axle (with tire manufacturer approval) for the meeting the designated tractor specification requirements.

The following low rolling resistance tires are SmartWay verified when used on class 8, line-haul tractor trailers:

Verified Low Rolling Resistance Retread Technologies

EPA demonstrated that certain low rolling resistance retread products can reduce NOx emissions and fuel use of long haul class 8 tractor-trailers by 3 percent or more, relative to other popular high rolling resistance retread products. These improvements are achieved when:

Verified retread technologies are used on both the drive and trailer axles. (Note: EPA has also demonstrated incremental fuel savings when low rolling resistance are used just on the tractor and/or just on the trailer.)
The retread technologies are used on the axle positions for which verification is specified.
Verified low rolling resistance steer tires are used.
All tires must be properly inflated according to the manufacturer’s specifications.

MULTI-POSITION APPLICATIONS AND USE WITH 6x2 TRACTORS:

Manufacturers specify the intended axle position(s) for retread technologies, and EPA’s verified list indicates retread technologies that achieve rolling resistance target values for those axle positions. Retread technologies verified for the trailer axle position meet the rolling resistance target for the drive axle, and if the tire performance characteristics are acceptable, the manufacturer may specify use for that application. Consequently, verified trailer retread technologies are acceptable for use on the tag (undriven) axle of 6X2 tractors if the manufacturer confirms the performance is acceptable for that application. Fleets should check with the manufacturer of such multi-position retread technologies to confirm that the product is suitable for the intended application.

Verified Idling Reduction Technologies

EPA has evaluated idle reduction technologies/devices as part of grants, cooperative agreements, emissions testing, engineering analyses, modeling, demonstration projects and external peer reviewed reports to study the effects of idling on air quality, fuel consumption and driver health. Based on this evaluation and research, EPA has determined that a variety of idle reduction technologies save fuel and reduce emissions when compared to idling the main engine.

Idle reduction technology allows engine operators to refrain from long-duration idling of the main propulsion engine by using an alternative technology. An idle reduction technology is generally defined as the installation of a technology or device that:

is installed on a vehicle (e.g., bus, truck, locomotive, automobile, marine vessel, equipment, etc.) or at a location, and
reduces unnecessary main engine idling of the vehicle or equipment, and/or
is designed to provide services (e.g., heat, air conditioning, and/or electricity) to the vehicle or equipment that would otherwise require the operation of the main drive engine while the vehicle or equipment is temporarily parked or remains stationary.

Certain idle reduction devices are now exempt from the federal excise tax when purchased with a new truck. For a list of idling reduction technologies eligible for the federal excise tax exemption, please see the Federal Excise Tax Exemption tab on this page.

To date, EPA has verified devices in the following categories of idle reduction technologies:

Electrified Parking Spaces (EPS) / Truck Stop Electrification (TSE)

An EPS system (also known as Truck Stop Electrification) operates independently of the truck’s engine and allows the truck engine to be turned off as the EPS system supplies heating, cooling, and electrical power. The EPS system provides off-board electrical power to operate either:

an independent heating, cooling, and electrical power system, or
a truck-integrated heating and cooling system, and may also include
a plug-in refrigeration system that would otherwise be powered by an engine.

In each case, the EPS system reduces engine operation by providing an alternative source of energy which results in lower emissions than the main engine.

SmartWay has verified technologies among the product lines of the following companies:

Shore Power Systems for Marine

Shore power systems allow maritime vessels to “plug into” land-based electrical power while at dock instead of using on-board diesel auxiliary engines. Shore power systems must enable a compatible vessel’s main and auxiliary engines to remain off while the vessel is at berth. Systems typically include various components such as cables, cable management systems, shore power coupler systems, distribution control systems, and power distribution.

Due to the unique nature and custom design of marine shore power connection systems, specific products and vendors are not listed. Marine shore power systems must comply with international shore power design standards (ISO/IEC/IEEE 80005-1-2012 High Voltage Shore Connection Systems or the IEC/PAS 80005-3:2014 Low Voltage Shore Connection Systems) and should be supplied with power sourced from the local utility grid.

Shore Connection Systems for Locomotives (SCS)

An SCS system allows locomotives to “plug into” an electrical power source instead of using its diesel engines while at the rail yard.

Idling-Reduction Strategies/Best Practices

It is common for drivers to run their engines to stay warm or cool in their trucks while resting after long hauls. And, of course, driver comfort is essential to the job.

Yet long-duration idling is costly to the driver, to the fleet owner, and to the environment. Some surveys show that trucks idle from six to eight hours a day for as many as 250 to 300 days each year. At current fuel prices, this can result in truck owners paying $6000 or more per year in fuel costs per truck.

Each year, long-duration idling of truck and locomotive engines consumes over one billion gallons of diesel fuel and emits 11 million tons of carbon dioxide, 200,000 tons of oxides of nitrogen, and 5,000 tons of particulate matter. Also, idling can increase engine maintenance costs, shorten engine life, harm driver well-being, and elevate noise levels

However, there are many alternatives to long-duration engine idling: they range in cost from a minimal investment to several thousand dollars. The alternatives can be divided into two broad categories: (Click on the blue text links below to learn more.)

Idling Reduction through Behavior Change

Here are some examples of ways to affect driver behavior:

State and Local Policy: Approximately 22 states and dozens of counties have promulgated laws that restrict the amount of time that a vehicle can idle its main engine. For a current list of state and local laws, see the American Transportation Research Institute's (ATRI's) list of state and local laws.
Driver/Operator Training: Educating drivers and operators about the impacts and adverse effects of long-duration idling can help change their behavior.
Financial Incentives: Fleet owners can offer financial incentives to drivers to reduce idling. Many large trucking companies already offer these incentives and have reported success in reducing idling times below national averages.

Instituting a company "no-idling" policy, and investing in education and incentives isn't enough, however, to deter a driver or operator from idling in extreme weather conditions. That's where technology solutions come into play.

Idling Reduction through Technology

There are five categories of technology-based idling reduction alternatives.

Automatic engine shut down/start up (locomotive)
An automatic engine shut down/start up system controls the engine by stopping or starting it without operator action, based on a set time period or ambient temperature, and other parameters (e.g., battery charge).
Fuel Operated Heaters -aka Direct-Fired Heaters (truck only)
These are small, lightweight heaters that burn fuel from the main engine fuel supply or a separate fuel reserve. They provide heat only and can be used in conjunction with cooling systems depending upon the cab comfort needs.
Diesel-Driven Heating System (locomotive only)
Designed to heat the coolant and oil to allow main engine shutdown in cold temperatures, the system does not use a generator to produce auxiliary power. Instead, it circulates and heats the engine coolant and oil to a target temperature of 120 F.
Auxiliary Power Units/Generator Sets (truck and locomotive)
These are small, diesel-powered engines (5 to 10 horsepower) that are installed on the truck to provide air conditioning, heat, and electrical power to run accessories like lights, on-board equipment, and appliances.
Electrification

Electrification refers to a technology that uses electricity-powered components to provide the operator with climate control and auxiliary power without having to idle the main engine. This can be on-board equipment (e.g., power inverters, plugs), off-board equipment (e.g., electrified parking spaces or systems that directly provide heating, cooling or other needs) or a combination of the two.

On October 27, 2003, EPA and the US Department of Transportation held the first national workshop on developing consistent truck stop electrification codes and electrical standards. Following this workshop, EPA published a Notice of Data Availability (NODA) in the Federal Register requesting comments and suggestions which would be used to better develop a national consensus. Truck Stop Electrification Codes and Electrical Standards; Notice of Data Availability (PDF) (13 pp, 157 KB, EPA420-R-05-002, January 2005) About PDFs) and related materials are available in the Federal Docket Management System.(NOTE: To access the docket from this link, select Advanced Search, then Docket Search, and then enter EPA-HQ-OAR-2003-0226 as the Docket ID.)

When companies adopt alternatives to long-duration idling, they can save money on fuel expenses, reduce engine maintenance costs, and reduce health effects from emissions and engine noise.

In addition to these company-level behavioral and technology alternatives, state and local governments are doing their part to help develop national strategies to promote alternatives to long-duration idling:

State and Local Idling Law Guidance

For the states, reducing idling translates into substantial reductions of air pollutants. For the trucking industry, reducing idling results in considerable fuel savings. According to EPA studies, long duration truck idling annually consumes more than one billion gallons of diesel fuel at considerable costs to the trucking industry. As a result, truck idling annually emits more than 11 million tons of carbon dioxide and more than 180,000 tons of nitrogen oxides, as well as fine particulate matter and other harmful air toxics.

Approximately 22 states and dozens of local counties have laws that limit the amount of time that a vehicle can idle its main engine.. To learn more, see the American Transportation Research Institute's (ATRI's) current list of state and local laws.

At the 2004 National Idle-Reduction Planning Conference hosted by the federal government, the trucking industry expressed concern about the inconsistent coverage and impractical design among existing state and local idling restriction laws. According to the trucking industry, truck drivers and owners lack knowledge and understanding of these laws, which decreases their ability to comply. In response to these concerns, EPA hosted a series of five public workshops.

The goal of the workshops was twofold: (1) to develop a model for a state idling law that would foster greater compliance through common understanding of requirements and ease of implementation; and (2) to raise awareness among the trucking industry, states, and environmental groups about each other's needs. For example, states and environmental groups want to reduce diesel emissions, and truck drivers need to rest comfortably and avoid fatigue-related vehicle accidents.

Below is a summary of each of the workshops.

July 26, 2005 - Hartford, CT (PDF) (13 pp, 109 K, EPA420-S-05-009, September 2005)

The product of these public workshops was a model state idling law (PDF) (15 pp, 312K, EPA420-S-06-001, April 2006) for states to consider adopting. EPA is not issuing any regulations about vehicle idling; the Agency's role is limited to that of a facilitator to help create more consistent idling laws across the country in hopes of achieving greater fuel savings, emission reductions, and increased compliance with such laws.

Air Quality Guidance for Idling Reduction

Reducing long-duration idling will reduce emissions of nitrogen oxides, carbon monoxide, and particulate matter. For state and local air quality planners and transportation officials, these emission reductions can be used in air quality plans such as state implementation plans and transportation and general conformity. EPA published a guidance document about quantifying and using locomotive idle emission reductions.

Guidance for Quantifying and Using Long Duration Switch Yard Locomotive Idling Emission Reductions in State Implementation Plans provides information about using emission reductions from locomotive idling reduction projects

Newly Updated SmartWay Trailer Designations

Historically, EPA SmartWay designated 53-foot dry vans as SmartWay trailers, which achieved 1% or more fuel savings with low rolling resistance tires, and 5% or more fuel savings with aerodynamic technology(s).

In 2015, SmartWay introduces 53-foot refrigerated trailers (PDF) (2 pp, 553K, EPA-420-F-15-010, February 2015) for SmartWay designation in addition to dry vans. Fleet managers can have confidence that fuel saving technologies will perform well for both dry van and refrigerated trailers.

For both refrigerated and dry vans, SmartWay introduces an Elite level of trailer designation (PDF) (2 pp, 633K, EPA-420-F-15-008, February 2015). Similar to the traditional SmartWay designated trailer, an Elite designated trailer will achieve 1% or more fuel savings from low rolling resistance tires. However, in using aerodynamic technologies to reduce wind drag, an Elite trailer may achieve 9% or higher fuel savings.

The 9% aerodynamic technology combinations are explained in more detail in the “Aerodynamics” tab.

How to Get an EPA-designated SmartWay Tractor

Fleet owners who purchase or lease SmartWay Tractors know they are using the cleanest, most fuel-efficient equipment available. SmartWay Transport Partners that purchase or lease SmartWay Tractors, and are in good standing are eligible to label the exterior of their SmartWay Tractors with the SmartWay mark.

Tractor Tire Specifications	Low-rolling resistance steer and drive tires (duals or singles aluminum wheels optional) that provide a 3 percent vehicle fuel economy benefit, relative to mid-range rolling resistance tires as defined by EPA. Approximately half the fuel savings, or about 1 percent, is contributed by the tractor steer and drive tires. See current qualifying trailer tire models on the verified tire technologies tabt: Additional tire models may be added in the future.	Commitment to replace the tires with currently qualifying low rolling resistance tractor tire models or retreads Maintain tires at manufacturer-recommended load and inflation pressures Tires that qualify for verification in the steer position also qualify for drive tire verification.

Tractor Wheels	EPA encourages (but does not require) the use of lighter-weight aluminum wheels rather than steel wheels, on the SmartWay tractor. Alcoa aluminum wheels Accuride aluminum wheels	Maintain per manufacturers service recommendations. Replace if necessary.

Idling Control	SmartWay truck carriers must employ at least one no-idle option capable of providing at least eight hours of idle-free auxiliary power, heat, and/or air conditioning. To ensure that the truck does not idle overnight on a year-round basis, a combination of idle reduction options may be needed. Each system must have at least eight hours of operating capacity. An auxiliary power unit or generator set Fuel operated heater Battery operated heating and/or cooling system Thermal Storage System See current qualifying idle reduction equipment on the verified idling technologies tab.:	Carriers (or SmartWay Partners) can either: Select tractor models equipped with idle reduction control technologies available from the truck manufacturer; Purchase and install a qualified after-market on-board idle reduction technology; or Opt to employ a documented, on-going and consistent (year-round) no-idling policy of: Using double drivers or providing overnight hotel stays for drivers Using truck stop electrification.*

*Truck stop electrification allows trucks to use electrical power from an external source. At properly equipped truck stops, drivers can shut the main truck engine off and plug into an electrical outlet that provides power for heaters, air conditioners, marker lights, and other accessories. Trucks need to be equipped with the required internal wiring, inverter system, and HVAC system to take advantage of truck stop electrification. Advanced truck stop electrification also provides electricity from an external source, but doesn't require the truck to be equipped with special systems. Truck parking bays are installed with equipment that provides the cab with electrical power, and heating, cooling, and other amenities like telecommunication hook ups, through an external console that fits into the truck's window frame. The truck-side console has temperature controls, an air supply and return pipe, a credit card reader, keypad, and a 100 VAC outlet.

SmartWay Trailer Equipment List


Base Trailer	Design: A EPA-designated SmartWay Trailer is a new dry freight box van or refrigerated trailer for long haul use of 53 feet or greater length. Additional trailer types may be added in the future. An older (or pre-owned)dry van or refrigerated trailer of 53 feet or greater length may also qualify if properly retrofitted. Dimensions:13 5 to 13 7 H, 53 L or greater, 102 outside W Weight: Assumes a standard dry van trailer of approximately 13,000 pounds or less, including weight of tires and wheels, but excluding weight of aerodynamic components

Trailer Tire Specifications	Low-rolling resistance trailer tires (duals or singles) are specifically identified for the trailer axle position. Low rolling resistance trailer tires contribute over 1% fuel savings relative to conventional tires. Aluminum wheels are optional; see current qualifying trailer tire models from the verified tire technologies tab. Additional tire models may be added in the future. Partners must commit to replace the tires with current qualifying low rolling resistance new or retread trailer tire models. Tires are to be maintained at manufacturer-recommended load and inflation pressures.

Trailer Wheels	EPA encourages (but does not require) the use of lighter-weight aluminum wheels rather than steel wheels, on the SmartWay trailer. Alcoa aluminum wheels Accuride aluminum wheels

Trailer Aerodynamics	See current qualifying aerodynamic equipment from manufacturers of the verified aerodynamic technologies tab: Additional aerodynamic technologies, manufacturers, and models may be added in the future. SmartWay Trailers must be equipped with a selection of aerodynamic technologies in the following configurations.

A SmartWay Designated Trailer may have the following components:

Typical Device Types	Description	Typical SmartWay Verified Fuel Savings
1. Trailer Front Fairing	Gap Reducer or fairing (to reduce turbulence between the tractor-trailer gap); can be verified as a standalone device, or part of an aerodynamic package.	1% or Higher
2. Trailer Under Fairing	Side Skirts or other under trailer devices; can be verified as a standalone device or part of an aerodynamic package	4%, 5% or Higher
3. Trailer Rear Fairing	Trailer end devices mounted on the rear or rear edges; can be verified as a standalone device or part of an aerodynamic package	1%, 4%, 5% or Higher
4. Low Rolling Resistance Tires	SmartWay Verified models are listed on the "Tires" tab	1% or Higher

The tables below list a few examples of the regular SmartWay Designated Trailer and the SmartWay Elite Trailer. These lists are by no way exhaustive; there are many ways to achieve both designations; these are simply a few common examples.

Examples of regular SmartWay Designated Trailers (53-foot box dry van or refrigerated trailer)	Potential Tire and Aerodynamic Device Combinations
Example 1: One Aero Device Plus Tires Total Fuel Savings: 6%	5% Trailer Side Skirt Low-rolling resistance tires (1%)
Example 2: One Aero Device Plus Tires Total Fuel Savings: 6%	5% Trailer End Fairing Low-rolling resistance tires (1%)
Example 3: Two Aero Devices Plus Tires Total Fuel Savings: 6%	1% Trailer End Fairing 4% Trailer Side Skirt Low-rolling resistance tires (1%)

Note: When using aerodynamic devices together, please keep in mind that not all devices can be installed on the same trailer at the same time. For instance, trailer fairings that mount under the center of the trailer cannot be used with trailer side skirts. Likewise, a trailer front fairing would not be appropriate for a refrigerated trailer.

*Examples of SmartWay Elite* Trailers (53-foot box dry van or refrigerated trailer)**	Potential Tire and Aerodynamic Device Combinations
Example 1: Your own a base trailer and in order to achieve the Elite designation, you buy a trailer skirt and a trailer end fairing separately and add new tires. Total Fuel Savings: 10%	4% Trailer Side Skirt 5% Trailer End Fairing Low-rolling resistance tires (1%)
Example 2: You own a base trailer and want to achieve the Elite designation without having to put anything on the back of the trailer. You decide to buy new tires along with a SmartWay verified Elite aerodynamic package that only uses a trailer front fairing and long trailer side skirt. Total Fuel Savings: 10%	9% SmartWay Elite Aerodynamic Combination Package (front fairing and long skirt) Low-rolling resistance tires (1%)
Example 3: Your trailer already has a 4% Skirt so you buy a new 5% trailer end fairing and tires. Total Fuel Savings: 10%	4% Trailer Side Skirt 5% Trailer End Fairing Low-rolling resistance tires (1%)
Example 4: You own a regular SmartWay Designated Trailer that uses a 5% skirt and low rolling resistance tires.

Federal Excise Tax Exemption

In the Energy Improvement and Extension Act (EIEA) of 2008 (PL 110-343), Section 206 excludes certain idling reduction devices and advanced insulation from the federal excise tax. This law amends section 4053 of the Internal Revenue Code.

For purposes of section 4053(9)(B) of the Internal Revenue Code, the Administrator of EPA, in consultation with the Secretary of Energy and the Secretary of Transportation, has determined that the devices (listed below under the FAQs) reduce the idling of a tractor at a motor vehicle rest stop or other location where such vehicles are temporarily parked or remain stationary. For the purposes of EIEA, the effective date of this list is the first day after the enactment of EIEA (October 4, 2008). Companies interested in adding their technology to this list should contact EPA after reviewing the criteria for product eligibility below.

Motor carriers must ensure that all devices installed on Commercial Motor Vehicles conform to the Federal Motor Carrier Safety Regulations, 49 CFR 393, Parts and Accessories Necessary for Safe Operation. Those regulations of particular concern to users of auxiliary power units are contained in section 393.28, section 393.30, and SubPart E of Part 393. These requirements dictate the specifications of installation of wiring and fuel systems for this equipment.

For more information about the tax exempt status of these idling reduction devices, please refer to the instructions for Form 720, Quarterly Federal Excise Tax Return, found at www.irs.gov. You may also contact Internal Revenue Service (IRS), Department of Treasury at (202) 622-3130.

Federal Excise Tax Exemption FAQs

Click on the questions below to see detailed answers.

"You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more."

When did some idling reduction devices become exempt from the federal excise tax?: On October 3, 2008, the President signed into law the Emergency Economic Stabilization Act of 2008 (Public Law 110-343). This law also enacted the Energy Improvement and Extension Act (EIEA) of 2008. Specifically, section 206 of the EIEA excludes some idling reduction devices and advanced insulation from the federal excise tax.
Does the excise tax exemption apply to idling reduction devices installed on all vehicles?: No. The exemption is only available for idling reduction devices installed on tractors. A tractor is a highway vehicle designed to tow a vehicle, such as a trailer or semi-trailer (aka an 18-wheeler). A tractor may carry incidental items of cargo when towing or limited amounts of cargo when not towing. (Reference: IRS Publication 510)
Does the consumer directly benefit from the federal excise tax exemption for idling reduction devices?: The truck excise tax, which is nominally 12% of the sales price, is triggered by an event such as the first sale or use of a taxable vehicle. The tax is destined for the Federal Highway Trust Fund and can be paid by the truck retailer or purchaser, but is generally collected and remitted by the seller. Since the tax is generally paid by the purchaser or lessor in conjunction with the sale or lease, the exemption for idling reduction devices serves to incentivize purchasers to order such devices in conjunction with the purchase or lease of a new taxable truck or tractor.
Where can I find information about federal excise taxes and how they work?: IRS Publication 510 offers a comprehensive explanation of federal excise taxes. Chapter 6 of Publication 510 offers information about the retail tax on heavy trucks, trailers, and tractors. Publication 510 is available on the IRS website. For more information regarding the tax exempt status of idling reduction devices, please read the instructions for Form 720, Quarterly Federal Excise Tax Return.
Who can I contact with tax questions about the excise tax exemption for idling reduction devices?: Contact the IRS Department of Treasury with any tax questions about idling reduction devices. They can be reached at (202) 622-3130.
Where can I find information about idling reduction?: Each year in the United States, the trucking industry consumes over one billion gallons of diesel fuel and emits over 11 million tons of CO2 and 200,000 tons of NOx while trucks are at idle. For more information about the benefits of idling reduction, please visit the idling technologies tab.
What is EPA's role in this federal excise tax exemption?: EPA, in consultation with the Departments of Energy and Transportation, identifies all eligible devices that reduce tractor idling. EPA publishes the list of approved idling reduction devices that are exempt from the federal excise tax.
Where can I find the list of EPA approved idling reduction devices?: The complete list of EPA approved idling reduction devices can be found on the Eligible Products list.
How does EPA approve idling reduction devices?: EPA evaluates idling reduction technologies by conducting emissions testing and engineering analyses to determine if a device should be approved as a verified technology. EPA also uses information gathered from EPA-funded grant projects, cooperative agreements, demonstration projects and external peer-reviewed reports to inform their decision.
If I'm a technology vendor, how do I add my product to EPA's approved technology list?: Vendors should contact Victor McMahan at mcmahan.victor@epa.gov or 202-343-9259 for more information.

Criteria for Federal Excise Tax Exemption

An idle reduction technology is defined a technology or device that:

is affixed to a tractor;
is designed to provide services (such as heat, air conditioning, and/or electricity) to the vehicle or equipment that would otherwise require the operation of the main drive engine while the vehicle or equipment is temporarily parked or remains stationary; and
reduces unnecessary idling of the vehicle or equipment.

EPA and the Department of Energy have evaluated idle reduction technologies and devices as part of grants, cooperative agreements, emissions testing, engineering analyses, modeling, demonstration projects and external peer reviewed reports to study the effects of idling on air quality, fuel consumption and driver health.

Based on this evaluation and research, EPA has determined that a variety of idle reduction technologies save fuel and reduce emissions when compared to idling the main engine. Qualified devices are added to EPA's list of verified idling control technologies; in the future, additional technologies and devices can be added to this list.

Motor carriers must ensure that all devices installed on Commercial Motor Vehicles conform to the Federal Motor Carrier Safety Regulations, 49 CFR 393, Parts and Accessories Necessary for Safe Operation. Those regulations of particular concern to users of auxiliary power units are contained in Section 393.28, Section 393.30, and SubPart E of Part 393. These requirements dictate the specifications of installation of wiring and fuel systems for this equipment.

Manufacturers should contact Anthony Erb at erb.anthony@epa.gov or 202-343-9259 for more information.

The devices listed on the exempted technology list (see "Eligible Products for the Federal Excise Tax Exemption" below) save fuel and reduce emissions when compared to idling the main engine.
