When should you dim your headlights when meeting or following another vehicle at night?

Dimming your headlights when meeting or following another vehicle at night is crucial for maintaining safety on the road. The proper distance to dim your headlights is 500 feet. This distance is significant because it allows the oncoming driver to avoid being blinded by your bright lights, ensuring that both drivers can see the road clearly without impairment. It also applies when you're following another vehicle, as bright headlights can reflect off the vehicle's rear view mirror, causing visibility issues and potential hazards. Following this guideline helps to promote safe driving practices and reduces the risk of accidents caused by impaired sight during nighttime driving.
