Weather, Visibility & EmergenciesStandalone practice
You are using high beams on a dark two-lane highway when a car comes toward you. By Missouri law, when must you switch to low beams?
A and B approach each other on a dark two-lane highway. Enlarged vehicle details identify A and the oncoming car.
Correct answer: When the oncoming car is within 500 feet
Why
High-beam glare can blind an oncoming driver at the moment the two vehicles are closest. Use high beams on dark roads when no one is coming, then switch to low beams in time for other drivers. While you pass an oncoming car, use the edge line of your lane as a guide instead of looking into its lights.
