Weather, Visibility & EmergenciesStandalone practice
You drive with your high beams on along a dark two-lane road. An oncoming car comes into view about 400 feet ahead. What should you do?
A and oncoming B are on a dark two-lane road 400 feet apart in a scaled overview, with enlarged vehicle details.
Correct answer: Switch to low beams now, because the car is already within 500 feet
Why
High beams let you see farther on dark open roads, so use them when no other vehicle is near. Their glare can blind another driver for a moment, and a blinded driver can drift into your lane. When you follow a vehicle, your high beams shine into its mirrors, so dim them within 300 feet.
