Arizona Drivers Permit Pactice Exam

When should you switch to low beams while driving?

1. When driving in heavy rain

2. When oncoming traffic is within 500 feet

3. When you're driving under streetlights

4. When you're following another vehicle closely

The correct answer is: When oncoming traffic is within 500 feet

Switching to low beams when oncoming traffic is within 500 feet is important for several reasons. High beams can be blinding to drivers approaching from the opposite direction, reducing their ability to see and safely navigate the roadway. This could lead to dangerous situations, including head-on collisions. Low beams provide sufficient visibility for your driving needs while helping to ensure the safety of other road users. Driving in heavy rain or under streetlights is generally more about adjusting visibility based on environmental conditions, but they do not specifically require low beams for safety in the same manner as oncoming traffic. Following another vehicle closely predominantly requires maintaining a safe distance and doesn't inherently demand the use of low beams unless visibility is compromised. However, keeping low beams on ensures you are using adequate lighting that is considerate of other drivers around you.
