What is the required distance under which vehicle lights must be on for visibility?

The required distance under which vehicle lights must be on for visibility is correctly stated as 1,000 feet. This regulation is in place to ensure that drivers are able to see clearly and be seen by others when visibility conditions are poor, such as during nighttime or inclement weather. When vehicle lights are activated at this distance, they enhance safety by allowing both the driver and others on the road to perceive the vehicle from a safe distance, reducing the risk of collisions. This requirement helps maintain safe driving practices and supports road safety standards.
