Arizona Drivers Permit Pactice Exam

When should your vehicle's low beam headlights be turned on?

1. When driving in bright daylight

2. When driving in fog, rain, or snow

3. When you are parked on the side of the road

4. When you see a sign that says 'low beam required'

The correct answer is: When driving in fog, rain, or snow

Turning on your vehicle's low beam headlights is important for ensuring visibility and safety under certain weather conditions. Low beam headlights should be activated when driving in fog, rain, or snow. This is because low beams provide adequate illumination of the road without causing glare that can reflect off precipitation, which could impair both your visibility and that of other drivers. When driving in these conditions, high beams can create a blinding effect due to the reflected light, making it harder to see. Using low beams in adverse weather helps improve your overall visibility of the road and assists other drivers in seeing you. In addition to providing better illumination close to the vehicle, they also help maintain a level of safety necessary when navigating through reduced visibility situations, like heavy rain or fog, ensuring that the driver can react appropriately to hazards.
