What is the distance within which a driver must dim their headlights before meeting another vehicle?

A driver must dim their headlights when approaching another vehicle within 500 feet to ensure the oncoming driver is not blinded by bright lights. This distance is crucial because it gives enough time for both drivers to see each other clearly and safely navigate the road. When headlights are too bright, it can create a dangerous situation, as the glare can impair the vision of the oncoming driver, increasing the risk of an accident. The regulation is in place to promote safety for all vehicle operators on the road, ensuring that visibility is maintained without causing inconvenience or danger to others.

In general, the distances specified by traffic laws are designed to enhance safety, and the choice of 500 feet has been established to strike a balance between adequate visibility for the driver and consideration for other road users.
