How far must tail lights be visible on a vehicle?

Tail lights must be visible from a distance of 500 feet when the vehicle is in normal operation. This distance is crucial for ensuring safety on the road, as it allows drivers behind a vehicle to notice its presence in low-light conditions or during adverse weather. Visibility of tail lights helps maintain safe driving distances and reduces the risk of rear-end collisions by providing an effective warning to other drivers when the vehicle is slowing down or stopping.

The regulation concerning tail light visibility is designed to enhance the overall safety of road users by ensuring that vehicles are easily identifiable from a significant distance. This standard aligns with safety guidelines that address how motor vehicles communicate their status to others on the road, particularly when managing traffic flow and preventing accidents.
