Turns, Lanes, Passing & MergingStandalone practice
What should you do while another vehicle is passing you on a two-lane road?
Blue A travels east in its normal right-hand lane. Silver B is temporarily using the opposing lane to pass A. The yellow center line is broken and no oncoming vehicle is shown.
Correct answer: Keep a steady speed or slow down, and keep right
Why
Cooperating with the pass provides room and visibility; accelerating can trap the passing driver beside you and increase collision risk.
