What color must tail lamps emit?

Tail lamps are required to emit red light as per Indiana traffic laws. This specification is crucial for safe driving, as the red color is universally recognized as a signal for vehicles to indicate that they are stopped or slowing down. This visibility is essential, particularly during low-light conditions or at night, allowing other drivers to perceive the vehicle's presence and intentions on the road.

The choice of red for tail lamps is standardized across many regions, including Indiana, to maintain uniform traffic signals. This agreement aids in reducing confusion among drivers, as red universally indicates the need to stop or exercise caution. Ensuring that tail lamps emit red light is an essential aspect of vehicle safety compliance for all motor vehicles operating on Indiana roads.
