Rear bumpers added to annual inspections
As of today, rear impact guards must be included in your DOT annual vehicle inspections.
The FMCSA has issued a new rule that adds rear impact guards to the list of criteria for passing an annual inspection, as found in Appendix A to Part 396. The criteria include details on the condition, placement, and size of the bumper, depending on vehicle type and year of manufacture.
This means:
? Your inspectors and technicians need to be familiar with the bumper inspection standards, and
? Your annual inspection forms must include “rear impact guard” as one of the items inspected, if applicable to your vehicles.
The rear impact guard — sometimes called an “ICC bumper,” after the name of the agency that first required them in 1952 — is required by 49 CFR §393.86, as well as by DOT manufacturing standards in Part 571.
As part of the new rule, the FMCSA revised §393.86 to exempt “road construction controlled horizontal discharge trailers” (as defined in §393.5) from the need for a rear impact guard.
One item missing from the new inspection criteria is the DOT certification label that manufacturers are required to place on each bumper. A missing label will not result in a failed inspection (and in fact, the FMCSA is deciding whether to remove the labeling requirement entirely).
The FMCSA did change the rules, however, to allow the label to be placed on either the front or back side of the bumper, rather than strictly on the forward-facing surface. This rule change simply aligns the FMCSA’s rules with current manufacturing standards.
The following bumper inspection standards are now found in Appendix A to Part 396 and must be used when performing DOT annual vehicle inspections as of December 9, 2021. Refer to §393.86 for exceptions. (Note that a vehicle with any of the following conditions will FAIL its inspection.)
Trailers and semitrailers with a GVWR of 10,001 pounds or more, manufactured on or after January 26, 1998:
? Missing guard.
? Guard is not securely attached to trailer, including broken or missing fasteners, any welds or parent metal cracked, or other damage that compromises secure attachment of the guard.
? Guard horizontal member does not extend to within 4 inches of each, or extends beyond either, side extremity of the vehicle.
? Guard horizontal member is more than 22 inches above the ground.
? Guard horizontal member is more than 12 inches forward of the rear extremity of the vehicle.
? Guard horizontal member does not have a cross sectional vertical height of at least 4 inches across its entire width.
Other commercial vehicles (1953 or newer) on which the vertical distance between the rear bottom edge of the body (or the chassis assembly if the chassis is the rearmost part of the vehicle) and the ground is greater than 30 inches when the vehicle is empty:
? Missing guard.
? Guard is not securely attached to trailer by bolts, welding, or other comparable means.
? Guard horizontal member is more than 30 inches above the ground.
? Guard horizontal member does not extend to within 18 inches of each side extremity of the vehicle.
? Guard horizontal member is more than 24 inches forward of the rear extremity of the vehicle.
Key to remember: If you haven’t already, be sure to add rear impact guards to the list of items you need to inspect annually on your commercial vehicles.
