What is the rule for using the left lane on a multi-lane highway?

• A. Use the left lane for passing or turning left; move to the right when not actively passing.
• B. Stay in the left lane at all times.
• C. Use the left lane only for going straight.
• D. The left lane is for slow traffic.

Answer: (A)

On a multi-lane highway, the left lane is meant for passing slower traffic or for turning left when needed. If you’re not actively passing, you should move back to the right-hand lanes so that the left lane stays available for those who need to overtake. This keeps traffic flowing smoothly and reduces bottlenecks. If you are driving at a similar speed to surrounding vehicles or faster, stay in the right lanes and let quicker drivers pass on the left. Use the left lane for passing and for left-turn movements, and return to the right once the pass or turn is completed.
