Texas Commission on Law Enforcement (TCOLE) Practice Exam

According to the Transportation Code, a lighting device or reflector mounted on the rear of a vehicle must be or reflect ______.

1. White

2. Red

3. Amber

4. Green

The correct answer is: Red

In the context of the Texas Transportation Code, a lighting device or reflector that is mounted on the rear of a vehicle is required to emit or reflect red light. This requirement is in place for safety reasons, as red is universally recognized as a signal for stopping or caution, making it crucial for other drivers to be aware of a vehicle's presence, especially from behind. The use of red lighting on the rear of vehicles helps to ensure that other road users, including pedestrians, cyclists, and drivers, can easily identify the rear of a vehicle, thus reducing the risk of accidents. In contrast, the other colors listed do not fulfill this specific safety function; for example, while white is typically used for headlights and amber for turn signals, these colors are not suitable for the rear positioning of vehicles. Such specifications enhance road safety and promote a consistent understanding among drivers regarding the signaling and warning functions of vehicle lighting.
