FMCSA Rules and Regulations on Lamps and Reflective Devices for Your Vehicle

Ryder Fleet Products Truck Reflector

In July, the Federal Motor Carrier Safety Administration, FMCSA, proposed a new regulation on lamps and reflective devices.   The agency is proposing to amend the Federal motor vehicle safety standard (FMVSS) on lamps and reflective devices.  Adoption of this proposal would increase manufacturer design flexibility without compromising safety or increasing costs.  In addition, it would also make the requirements of the standard more in line with European regulations.

All commercial motor vehicles manufactured on or after December 25, 1968, must, at a minimum, meet the applicable requirements of 49 CFR 571.108 (FMVSS No. 108) in effect at the time of manufacture of the vehicle.   The purpose of this is to reduce traffic accidents and deaths and injuries resulting from traffic accidents, by providing adequate illumination of the roadway, and by enhancing the conspicuity of motor vehicles on the public roads so that their presence is perceived and their signals understood, both in daylight and in darkness or other conditions of reduced visibility.

Commercial motor vehicles manufactured before December 25, 1968, must, at a minimum, meet the requirements of subpart B of part 393 in effect at the time of manufacture.  Subpart B states that lamps and reflective devices/material required by this subpart must not be obscured by the tailboard, or by any part of the load, or its covering by dirt, or other added vehicle or work equipment, or otherwise.
