A signaling device on the rear of a vehicle may be which of the following colors?

The signaling device on the rear of a vehicle is typically utilized to communicate important information to other drivers, such as indicating stops, turns, or hazards. The correct answer reflects the standard colors used for these signaling devices—red for brake lights and amber (or yellow) for turn signals and hazard lights. Red signals warning and caution, while amber/yellow indicates the intention to turn or to alert others of a potential hazard. This adherence to color coding helps promote road safety through consistent understanding among drivers of what each signal means.

The other options do not align with established vehicle signaling standards. Colors like blue, green, orange, pink, purple, and black are not commonly used for rear signaling devices, making them less effective for communication on the road. Therefore, understanding the importance and implications of using red and amber/yellow colors for signaling can help reinforce safe driving practices.
