Where is it illegal to have a red light showing on a vehicle?

Having a red light showing on the front of your vehicle is illegal because red lights are universally recognized as indicators of stopping or emergencies. In traffic regulations, red lights at the front of a vehicle can confuse other drivers regarding your intentions, as they typically expect red to mean "stop." This can pose a significant safety hazard on the road.

In contrast, red lights are often permitted on the rear of a vehicle, as they serve important functions such as brake lights and tail lights, signaling to drivers behind that the vehicle is in motion or stopping. Additionally, red lights can also be seen on emergency vehicles to indicate their presence and signal caution to other road users.

By understanding the legality of vehicle lighting, drivers can help ensure clearer communication on the roadway, enhancing safety for all users.
