What must trailers with a gross weight of 3,000 pounds or less include for visibility?

Trailers with a gross weight of 3,000 pounds or less must include reflectors that are visible for 300 feet to enhance visibility, particularly in low-light conditions or at night. The use of reflectors helps other drivers see the trailer from a distance, which is crucial for safety on the road. This regulation ensures that even smaller trailers, which may not have the same visibility as larger vehicles, can still be seen by oncoming traffic, reducing the risk of accidents.

Flashing lights, warning signs, and backup alarms are features that may be used on various vehicles for signaling or alerting purposes but are not specifically required for smaller trailers in the same way that reflectors are. Reflectors serve a fundamental role in road safety by providing essential visibility cues, which is why they are a mandated requirement for these types of trailers.
