Texas Basic Peace Officer Certification Practice Exam

At least two reflectors on the rear of a motor vehicle, trailer, semitrailer, or pole trailer must be __________ in color.

1. yellow.

2. red.

3. amber.

4. white.

The correct answer is: red.

The correct answer, red, reflects the legal requirements for the visibility and identification of vehicles on the road. Red reflectors are specifically mandated for use on the rear of vehicles, trailers, semitrailers, and pole trailers to ensure that they are easily seen by other drivers, particularly in low light or nighttime conditions. This color is distinctly associated with the rear of vehicles and serves to alert drivers approaching from behind that there is a vehicle present, which is crucial for preventing accidents and enhancing safety on the road. In contrast, yellow reflectors are typically used for marking the sides of vehicles and indicating caution, while amber reflectors are often employed for vehicles and objects that might require caution, like construction zones or slow-moving vehicles. White reflectors are generally used on the front of vehicles for visibility purposes. Thus, the requirement for red reflectors on the rear aligns with safety protocols aimed at reducing the risk of rear-end collisions and improving visibility for all road users.
