Which of the following is required on the rear of a trailer that is less than 80 inches in width?

• A. 1 rearview mirror
• B. 2 red stop-lamps on each side
• C. 1 red reflector
• D. 2 amber side markers

Answer: (B)

The requirement for trailers that are less than 80 inches in width is specifically focused on safety and visibility. According to Texas CDL regulations, trailers of this width must be equipped with at least two red stop lamps that are visible from the rear, one being on each side of the trailer. This is crucial for alerting drivers behind the trailer when it is decelerating or stopping, thereby reducing the risk of accidents.

The presence of these stop lamps is a critical safety feature, as they provide essential visibility and signal the driver’s intent to stop or slow down, especially in situations where the trailer may be towing a load or when visibility is poorer.
