What is the minimum distance that hazard lights must be visible from in normal sunlight?

The minimum distance that hazard lights must be visible from in normal sunlight is 500 feet. This requirement is established to ensure that other drivers can clearly see a vehicle that is experiencing trouble or is stopped on the roadway. The visibility of hazard lights from this distance helps to reduce the risk of accidents, as it allows approaching drivers ample time to react to the situation ahead.

The specification of 500 feet is based on the average reaction times and stopping distances in typical driving conditions, emphasizing the importance of safety on the roadway. This standard is particularly critical in ensuring that vehicles displaying hazard lights are clearly visible to other road users, thereby enhancing overall traffic safety.
