How many rear reflectors must be present on each side of trailers with a gross weight over 3,000 pounds?

For trailers with a gross weight exceeding 3,000 pounds, the requirement is to have two rear reflectors installed on each side. This regulation is put in place to enhance visibility and safety on the road, especially in low-light conditions. The presence of two reflectors ensures that the trailer is adequately marked and can be seen by other drivers, which helps prevent accidents and increases overall road safety.

Having only one reflector would not provide sufficient visibility, and more reflectors, such as three or four, are not required and could unnecessarily complicate compliance. Therefore, the requirement for two reflectors strikes the right balance between safety and practicality.
