It’s a hit! New rear bumper interpretation helps the industry
A missing rear impact guard (bumper) label is not to be considered a violation during a roadside inspection, according to an FAQ published by the Federal Motor Carrier Safety Administration (FMCSA).
The FAQ was issued in response to concerns expressed by the industry and the Commercial Vehicle Safety Alliance (CVSA).
History of rear bumper violations
Several years ago, due to pressure from Congress and other groups, FMCSA asked that the rear impact guard (bumper) regulations be more actively enforced. These regulations are found in 393.86 of the FMCSA regulations. In paragraph (a) of this section (393.86(a)) are the requirements for trailers with a GVWR of 10,000 pounds or more built on or after January 26, 1998.
One of these requirements (393.86(a)(6)) is that the rear bumper must have a manufacturer label certifying that the bumper meets the requirements of Federal Motor Vehicle Safety Standard 223 (FMVSS 223, or 571.223). As a result, officers on the road were citing trailers that did not have the manufacturer certification label on their rear bumper.
An issue arose because when the label is missing or unreadable, the only recourse the carrier has is to contact the trailer manufacturer for a replacement label. However, manufacturers are hesitant to issue a new manufacturer certification label to an old trailer.
Due to pressure from the industry and officers, CVSA petitioned FMCSA for a rule change and asked officers to not enforce the label regulation until the petition was resolved. In September 2024, FMCSA denied the petition, opening the door to rear bumper label violations once again. However, CVSA asked FMCSA to reconsider and ask officers to not issue violations for missing labels until FMCSA had reconsidered.
New interpretation
On December 10, 2024, FMCSA released an FAQ (a form of guidance for the industry and officers) stating that an illegible, incomplete, or missing rear impact guard certification label is not a violation of 393.86(a)(6). In the FAQ, it states what should be inspected on trailer rear impact guards/bumpers (during carrier and roadside inspections) is compliance with the following requirements:
- General requirements (trailers covered by this regulation must be equipped with a bumper meeting these standards that is in good condition, see 393.86(a)(1));
- Guard width (guard must reach to within 4 inches of the side of the trailer, 393.86(a)(2));
- Guard height (guard can be no higher than 22 inches above the ground, 393.86(a)(3));
- Guard rear surface (guard must be within 12 inches of the rear of the trailer, 393.86(a)(4)); and
- Cross-sectional vertical height of the horizontal member (the main crossbar on the guard must be a minimum of 4 inches, 393.86(a)(5).
Key to remember: This new FAQ puts to rest the issue of illegible, incomplete, or missing rear impact guard certification label and provides carriers guidance on what technicians and drivers should be checking during inspections.
