When driving at night, when should you use your high beam headlights?

When driving in a school zone
When driving in heavy traffic
When you are the only vehicle on the road
When you are following another vehicle

The correct answer is: When you are the only vehicle on the road

Driving with high beam headlights on can provide better visibility in the dark, but it can also create glare for other drivers. Therefore, high beam headlights should only be used when there are no other vehicles present, as option C suggests. Using high beams in heavy traffic or in a school zone can temporarily blind or distract other drivers and pedestrians, creating a safety hazard. It is also important to turn off high beams when following another vehicle to avoid creating glare for the driver ahead.
