  • Are headlamps properly aimed without excessive upward deflection that could blind oncoming drivers?
  • Are front fog or driving lights (if equipped) operational and properly aimed?

Tail Lamps and Brake Lamps

Verify all rear-facing tail lights and stop/brake lights are operational on both the power unit and any trailer.

  • Are all required tail lamps operational and emitting red light at the rear?
  • Are all brake/stop lamps operational on the power unit when the brake pedal is depressed?
  • Are trailer tail lamps and brake lamps operational via the electrical connection?
  • Is the high-mounted center stop lamp (CHMSL) operational on the power unit?
  • Are tail and stop lamp lenses red, uncracked, and free of damage that allows white light to show to the rear?

Turn Signals and Hazard Warning Flashers

Test all turn signal and hazard warning flasher functions for correct operation and flash rate.

  • Are all four turn signal lamps (front and rear, both sides) operational?
  • Do turn signals flash at the correct rate (60-120 flashes per minute)?
  • Do trailer turn signals function correctly via the electrical connection?

Reflectors and Conspicuity Tape

Verify all required reflectors and retroreflective sheeting are in place, undamaged, and properly positioned.

  • Are front and rear reflectors present, undamaged, and the correct color (amber front, red rear)?
  • Does the trailer have required retroreflective sheeting or reflex reflectors along the sides and rear?
  • Is the retroreflective sheeting free of peeling, fading, or damage that significantly reduces reflectivity?
  • Are side marker reflectors present and undamaged on both sides of the trailer?

Backup, Auxiliary, and Specialty Lighting

Inspect backup lights, work lights, strobe lighting, and any other specialty lamps for condition and operation.

  • Are backup (reverse) lamps operational and illuminating white when the vehicle is placed in reverse?
  • Is the backup alarm (if required or equipped) operational when the vehicle is placed in reverse?
  • Are work lights or spot lights (if equipped) functional and aimed to avoid blinding other road users?
  • Are emergency/warning strobe or beacon lights (if equipped) operational?
  • Are interior cab lights (dash, step, and cargo area lights if equipped) in working order?

Electrical System and Lamp Controls

Verify the vehicle electrical system supporting all lighting is functioning correctly, including switches, fuses, and wiring.

  • Do all lighting switches (headlamp, parking, marker) operate correctly without intermittent failure?
  • Are there any blown fuses or tripped circuit breakers affecting lighting circuits?
  • Is visible wiring to lighting fixtures free of fraying, bare conductors, or improper splices?
