Reflectors on Trailers: What You Need to Know

How many reflectors must every trailer, semi trailer, or pole-trailer have on the rear?

A. One red rear reflector
B. Two red rear reflectors
C. Three red rear reflectors
D. Four red rear reflectors

Final answer:

Trailers, semi trailers, or pole-trailers must have a minimum of two red rear reflectors.

The number of reflectors required on the rear of a trailer, semi trailer, or pole-trailer can vary depending on the specific regulations of the region or country. In the United States, for example, Federal Motor Vehicle Safety Standards (FMVSS) require trailers to have at least two red rear reflectors.

These reflectors help improve the visibility of the trailer to other drivers, especially at night or in low-light conditions. They reflect the light from the headlights of other vehicles back towards the source, making the trailer more easily noticeable.

It's important for drivers to maintain the reflectors on their trailers in good condition and in proper placement according to the regulations to ensure safety on the road.
