For trailers weighing 3,000 pounds or less, what is required on the rear of the vehicle?

For trailers weighing 3,000 pounds or less, they must be equipped with two red reflectors that are visible for a distance of 300 feet. This requirement is in place to enhance visibility and safety on the road, particularly in low light conditions or adverse weather. The red color of the reflectors is designed to alert other drivers to the presence of the trailer from behind, helping to prevent accidents.

Reflectors play a crucial role in indicating the outline and size of the trailer, making it easier for other drivers to gauge the distance and position of the trailer on the road. This is essential for maintaining safety standards and ensuring that both the trailer and towing vehicle are visible to other road users.

In contrast, the other options, which suggest different types of lighting or reflectors, do not meet the specific regulatory requirements for trailers in this weight category. It's important for drivers to be aware of these specifications to comply with state laws and promote safety while traveling.
