2024 New York Cdl DMV Practice Test #5

Turning on the windshield wipers is ineffective for clearing fog and may obstruct visibility further.

Increasing the speed of the vehicle does not clear fog more quickly and can be dangerous if visibility is impaired.

Use the windshield defroster to clear the fog. When your commercial vehicle's windshield becomes fogged, it's essential to use the windshield defroster to clear the fog and improve visibility. This setting directs warm air onto the windshield, helping to dissipate the fog and ensure clear visibility while driving.

Ignoring the fog and continuing to drive without addressing the visibility issue poses significant safety risks for you and other road users.
