Every trailer must have how many reflectors on the rear?

Every trailer must have two reflectors on the rear to ensure visibility and safety. The requirement for two reflectors helps to enhance the visibility of the trailer to other drivers, especially in low-light conditions or during adverse weather. This visibility is crucial for preventing accidents by making it clear where the trailer is located on the road.

Additionally, having two reflectors provides a more balanced reflection of light from vehicles behind the trailer, further improving safety. The specific placement and number of reflectors are part of regulations designed to ensure that trailers meet safety standards and can be seen effectively from a distance. Thus, the requirement of two reflectors is a critical factor in promoting roadway safety.
