Philadelphia Drivers License Practice Test

When are you permitted to use high beam lights?

1. At all times

2. Only from 10 PM to 6 AM

3. At night when more than 500 ft. from an approaching car

4. When driving in urban areas

The correct answer is: At night when more than 500 ft. from an approaching car

High beam headlights are designed to provide greater visibility at night when there are no oncoming vehicles or when driving on unlit roads. The regulations specify that you are permitted to use high beams when you are at least 500 feet away from an approaching vehicle. This distance allows you to utilize the increased illumination range of high beams without blinding other drivers, which can create hazardous conditions. During nighttime driving, particularly on roads without streetlights, using high beams can significantly enhance your ability to see potential obstacles or hazards. However, it is crucial to switch to low beams when you are within the specified distance of oncoming traffic or when following another vehicle closely, as using high beams in these situations can impair the vision of other drivers. This regulation helps ensure the safety of all road users, making it clear when high beams are appropriate to use.
