How far must tail lights be visible from?

The requirement for tail lights to be visible from a specified distance is crucial for safety on the road. This visibility allows other drivers to see the vehicle from behind, especially during low light conditions or adverse weather. Tail lights must be visible from at least 500 feet, ensuring a safe distance for vehicles on the roadway to react appropriately when slowing down or stopping.

This regulation helps in preventing accidents by ensuring that drivers behind are aware of the intentions and actions of the vehicle in front. When tail lights are functioning correctly and are within this visibility standard, they play a vital role in communication between drivers, contributing to overall road safety.

Other distances provided in the options may not be sufficient to ensure that following vehicles have adequate time to respond to changes in the speed or direction of the vehicle displaying the tail lights. This is why the standard of 500 feet is emphasized as necessary for effective visibility.
