From what distance must tail lamps be visible?

Tail lamps must be visible from a distance of 1,000 feet away to ensure that vehicles behind can see a stopped or slowing vehicle, providing critical information for safe driving. This regulation helps prevent accidents by giving enough warning time for approaching drivers to react appropriately to the vehicle's status. Visibility from this distance contributes significantly to road safety, especially in low-light conditions or when visibility is compromised due to weather.

The distances of 500 feet, 750 feet, and 1,200 feet do not align with standard regulations for tail lamp visibility, either being below the minimum requirement or exceeding typical safety standards for practical visibility on roadways.
