Dear Mr. Gest:

This responds to your request for clarification of the responsibilities set forth in 49 CFR 595.7(e)(5) regarding certain disclosure requirements related to vehicle modifications made for a person with a disability. Among the requirements set forth in this section is a statement of the load carrying capacity of the vehicle if it has been reduced by more than 100 kilograms (220 pounds). You are specifically interested in determining whether the disclosure requirement applies to vehicle alterers, i.e., persons or companies that modify a vehicle prior to its first retail sale.

The short answer to your question is that alterers do not have to specifically disclose a reduction in load carrying capacity that is the result of their alterations. They do, however, have to take adequate load carrying capacity into account when they determine whether the alterations have changed a vehicle's gross vehicle weight rating (GVWR).

By way of background, the National Highway Traffic Safety Administration (NHTSA) administers a statute requiring that motor vehicles manufactured for sale in the United States or imported into the United States be manufactured so as to reduce the likelihood of motor vehicle crashes and of deaths and injuries when crashes do occur. We refer to that statute as the Vehicle Safety Act. It is codified at 49 U.S.C. 30101, et seq.

One of the agencys functions under the Vehicle Safety Act is to issue and enforce Federal motor vehicle safety standards (FMVSSs). These standards specify safety performance requirements for motor vehicles and/or items of motor vehicle equipment. Manufacturers of motor vehicles must certify compliance with all applicable safety standards and permanently apply a label to each vehicle stating that the vehicle complies with all applicable FMVSSs and providing the GVWR.

NHTSA's regulations impose certain requirements on those who alter a vehicle that has been previously certified by a manufacturer but not yet sold in good faith for purposes other than resale. Alterers are considered to be manufacturers and are responsible for ensuring that the vehicle continues to meet all applicable federal safety standards when delivered to the first retail customer. Alterers must determine whether their modifications could affect the vehicle manufacturer's certification of compliance and, if so, must apply a label adjacent to the original manufacturer's certification label stating that the vehicle, as altered, conforms with all applicable standards.

Alterers must also determine whether their modifications affect the manufacturer's stated GVWR, gross axle weight rating (GAWR), and vehicle type. If such a change has been made, the alterer must specify the new GVWR, GAWR, or vehicle type in a manner consistent with the capability of the vehicle to comply with applicable standards and operate at higher weight rating and/or as a different type of vehicle. NHTSA expects both manufacturers and alterers to assign GVWR and GAWRs that reflect the manufacturer's or alterer's good-faith evaluation of how the vehicle's braking, load bearing items (including tires), suspension, steering, and drive train components will react to the vehicle's weight, size, cargo-carrying capacity and intended use.

The term GVWR is defined in 49 CFR 571.3 as "the value specified by the manufacturer as the loaded weight of a single vehicle." The GVWR informs vehicle owners how heavily the vehicle may be safely loaded. It also affects the vehicle's loading and other test conditions for the performance tests to ascertain whether the vehicle complies with applicable safety standards.

The only express regulatory limitation on the GVWR that manufacturers may assign to their vehicles is set forth in 49 CFR 567.4(g)(3), which provides that the assigned GVWR "shall not be less than the sum of the unloaded vehicle weight, rated cargo load, and 150 pounds times the vehicle's designated seating capacity." "Unloaded vehicle weight" is defined in 49 CFR 571.3 as "the weight of a vehicle with maximum capacity of all fluids necessary for operation of the vehicle, but without cargo, occupants, or accessories that are ordinarily removed from the vehicle when they are not in use." Although the term "rated cargo load" is not defined by regulation, generally it is the GVWR of the vehicle minus the combined weight of the occupied designated seating positions (150 pounds times the total number of designated seating positions) and the unloaded vehicle weight.

Those who modify a completed vehicle after the first retail sale are considered to be repair businesses by NHTSA and are typically called "modifiers" by the industry. The Vehicle Safety Act prohibits manufacturers, distributors, dealers, or motor vehicle repair businesses from knowingly making inoperative any part of a device or element of design installed on or in a motor vehicle or motor vehicle equipment that is in compliance with any applicable federal motor vehicle safety standard. NHTSA may assess a civil penalty to enforce this provision. NHTSA may also, through regulation, exempt a person or business from the prohibition if it decides that an exemption is consistent with motor vehicle safety and the Vehicle Safety Act.

On February 27, 2001, NHTSA published a final rule setting forth a limited exemption from the make inoperative prohibition for businesses or individuals who modify vehicles for persons with disabilities (66 Federal Register 12638; Docket No. NHTSA-01-8667). This exemption is codified in 49 CFR Part 595, subpart C. Only portions of some Federal motor vehicle safety standards are covered by the exemption.

An underlying premise of Part 595 is that the individual for whom the modifications were made is unlikely to realize that the vehicle, as modified, may no longer meet all applicable FMVSS and may have a different load carrying capacity than listed in the owner's manual or on a tire placard. These vehicle changes could have an effect on the overall performance of the vehicle. Accordingly, we determined that vehicle modifiers who decide to take advantage of the exemption set forth in 49 CFR Part 595 should be required to provide the customer with certain safety information and place a permanent label on the vehicle. The language for the label is set out in 49 CFR 595.7(d), and a detailed breakdown of the required information is contained in 49 CFR 595.7(e). One of the required pieces of information is the vehicle's load carrying capacity when it has been reduced by 100 kilograms (220 pounds) or more.

This requirement was intended to address circumstances in which the load carrying capacity has been reduced as a result of the modification. Although the term "load carrying capacity" was not specifically defined in the February 2001 final rule, the term was intended to convey the same meaning as vehicle capacity weight, as defined in FMVSS No. 110, Tire selection and rims. "Vehicle capacity weight" is defined in that standard as the rated cargo and luggage load plus 68 kilograms (150 pounds) times the vehicle's designated seating capacity, i.e, the number of designated seating positions.

The vehicle capacity weight for passenger cars is stated on a placard located on the glove compartment door or an equally accessible location. For other vehicles, such as vans, vehicle capacity weight and/or rated cargo load and luggage values may be stated on a label voluntarily affixed by the vehicle manufacturer or alterer or in the owner's manual. If no information is provided, a vehicle's load carrying capacity prior to modification is its GVWR minus its unloaded weight. Likewise, the term "available load capacity" means that load carrying capacity that remains after the modifications are completed. For a comprehensive discussion regarding the determination of "reduction in load carrying capacity," see the enclosed letters to Mark S. Lore and Kenneth Conaway, dated April 25, 2002.

Should you require any additional information or assistance, please contact Rebecca MacPherson, of my staff, (202) 366-2992 or at the address given above.

Sincerely,
Jacqueline Glassman
