What is the visibility requirement for the lights on vehicles over 25 feet long?

The visibility requirement for the lights on vehicles over 25 feet long is that they must be visible from 500 feet away. This regulation is in place to enhance safety on the roads, ensuring that other drivers can see larger vehicles from a sufficient distance. The increased visibility helps to reduce the risk of accidents by alerting other drivers to the presence of these larger vehicles, which have a longer stopping distance and may require more space on the road.

The requirement for visibility from this distance is particularly important for vehicles that may not maneuver as easily as smaller vehicles, giving other drivers ample time to react and maintain safe distances. Larger vehicles often have blind spots that can obscure their surroundings, making it critical for their lights to be visible to enhance safety on the road.
