A signaling device on the rear of a vehicle can be what colors?

A signaling device on the rear of a vehicle is generally required to be red, amber, or yellow, as these colors effectively communicate important information to other drivers.

Red is commonly used for brake lights and tail lights, indicating that a vehicle is slowing down or stopping. Amber or yellow lights are typically used for turn signals and hazard lights, allowing the driver to communicate their intention to change direction or warn others of a potential hazard. This color coding is standardized to ensure clarity and safety on the roadways.

The other color options present in the choices are not standard for rear signaling devices. White is usually used for reverse lights, which signal when a vehicle is backing up, while colors like green, orange, and purple do not have widely accepted meanings in traffic signaling at the rear of vehicles. The adherence to specific colors for signaling minimizes confusion and promotes safer driving behaviors among all road users.
