Why do you inspect the rear impact guard (underride guard) and conspicuity reflectors/reflective tape on a trailer?
- A.They help keep a following car from sliding under the trailer and make the trailer visible at night; damaged or missing ones are defects
- B.They are decorative and never inspected
- C.They add braking power in a rear-end collision
- D.They are only required on trailers parked at docks
Correct answer
A. They help keep a following car from sliding under the trailer and make the trailer visible at night; damaged or missing ones are defects
Why
The guard is a safety device for others, and the reflective treatment is how drivers judge your trailer's presence and width at night. Both are part of a lawful, complete trailer inspection.
