During a pre-trip vehicle inspection, a commercial driver must verify that all exterior lighting devices and reflectors show the proper regulatory color based on their mounting position. Match each exterior lighting component to its required lens color and regulatory function.
- Front clearance and identification lightsMust be amber to indicate vehicle width and presence from the front
- Rear tail, brake, and clearance lightsMust be red to warn trailing traffic of vehicle presence, width, and deceleration
- License plate light and backup lampsMust be white to illuminate the registration plate or provide rearward illumination while reversing
- Intermediate side marker lights on long trailersMust be amber to indicate vehicle length along the center section
Cevap
Front clearance and identification lights match with amber forward illumination; Rear tail, brake, and clearance lights match with red rearward warning; License plate light and backup lamps match with white illumination; Intermediate side marker lights match with amber midpoint length marking.
Federal Motor Carrier Safety Regulations (FMCSRs) establish strict color-coding for commercial motor vehicle exterior lighting: amber to the front and forward/intermediate sides, red to the rear and rear sides, and white for license plate lamps and reverse lamps.
