Headlight glare — Maine Permit Test

Use low beams in fog, snow or heavy rain, because light from high beams reflects back off the precipitation and causes glare.

High beams in fog throw a white wall back at you and you see less.

Use low beams in fog, snow, or heavy rain as light from your own high beams will reflect back on you from such precipitation and cause a glare that will affect your vision.

If an oncoming driver fails to dim the high beams, slow down and look toward the right side of the road.

Staring into the lights leaves you blinded just as the car goes by.

If a vehicle comes toward you with high beams on, and fails to dim the lights, slow down and look toward the right side of the road.

Do not keep your bright lights on to get back at a driver who will not dim; if you do, both drivers will be blinded.

Two blinded drivers meeting on a dark road is how a head-on crash happens.

Do not try to "get back" at the other driver by keeping your bright lights on. If you do, both drivers will be blinded.

Why use low beams in fog, snow or heavy rain?

Brighter light reflects back as glare. High beams in fog throw a white wall back at you and you see less. Maine Driver’s License Manual, p.90: “Use low beams in fog, snow, or heavy rain as light from your own high beams will reflect back on you from such precipitation and cause a glare that will affect your vision.”
