Arizona Driving Permit Written Practice Test

At what distance must you dim your high beams when approaching another vehicle?

1. 200 feet

2. 300 feet

3. 500 feet

4. 700 feet

The correct answer is: 500 feet

The requirement to dim your high beams when approaching another vehicle is set at a distance of 500 feet. This regulation is in place to ensure that the bright lights from your vehicle do not blind or distract the oncoming driver, which is critical for safety on the road. High beams are much brighter than low beams and can severely impair the vision of other drivers. By dimming your lights from a distance of 500 feet, you are providing sufficient time for the oncoming driver to adjust to your vehicle’s light intensity, thus reducing the risk of accidents caused by momentary blindness or visual impairment. This regulation also reflects proper driving etiquette and consideration for other drivers on the road, enhancing overall traffic safety during night driving conditions. Being aware of this distance helps drivers contribute to a safer environment for all road users.
