An operator shall dim headlights when an approaching vehicle is within how many feet?

Dimming headlights when an approaching vehicle is within 500 feet is crucial for road safety and visibility. The purpose of this practice is to prevent blinding the driver of an oncoming vehicle. High beams can significantly impair visibility for other drivers, particularly at night or in low-light conditions.

By adhering to the 500-foot guideline, drivers allow the other vehicle's operator to maintain clear vision, which enhances the overall safety of both drivers. This rule helps ensure that everyone on the road can see clearly and respond appropriately to their surroundings, reducing the risk of accidents caused by temporary vision impairment due to bright lights. The 500-foot standard is widely accepted in traffic laws to promote responsible driving behavior in situations where visibility is compromised.
