Utility's I.C.C. Bumper. (Photo: Business Wire) Federal Motor Carrier Safety Administration (FMCSA) recently proposed to include the rear impact guard on the list of items that need to be examined during a commercial vehicle’s annual inspection. Utility strongly recommends their 7” deep horizontal bumper for horizontal bumper replacement on new or older Utility trailer models that were built after 2002 in order to exceed all rear trailer guard safety regulations. Utility will discount the new bumpers as an incentive to replace the old bumpers with the new upgraded 7” deep bumper.
