From what distance must tail lamps be visible?

Tail lamps must be visible from a distance of 100 feet. This standard is crucial for ensuring the safety of drivers and vehicles on the road, as it allows other drivers to see the rear lights of a vehicle when it's dark or in low-visibility conditions. Proper visibility of tail lights signals to other road users that a vehicle is present and indicates its position, especially when braking or making turns. This regulation is part of vehicle safety requirements, aimed at preventing accidents and enhancing overall road safety.
