How far must tail lights be visible from a vehicle?

Tail lights must be visible from a distance of 500 feet in Montana. This requirement is crucial for ensuring that vehicles are easily seen from behind, especially in low-light conditions or inclement weather. The visibility range helps to prevent accidents by allowing drivers behind a vehicle to see its position and whether it is slowing down or stopping. Properly functioning tail lights enhance safety on the roads by providing necessary cues to other drivers about the vehicle's movements. This standard distance is designed to ensure visibility at a safe stopping distance, contributing to overall traffic safety.
