Weather, Visibility & EmergenciesStandalone practice
You are operating the windshield wipers continuously because rain impairs visibility. What does Maryland law require?
Correct answer: Turn on the headlights.
Why
Turn on the headlights when continuous wiper operation is needed because weather impairs visibility. The manual also recommends the broader habit of using headlights with wipers. Parking lights alone are not headlights, and high beams can worsen glare in rain or fog.
