Before moving left to overtake another vehicle, what should you do?
Correct answer: C – Signal and begin the pass only when it can be completed safely
Alaska requires an appropriate signal before moving left, and the movement must appear reasonably safe. When a pass uses a lane for oncoming traffic, that lane must be clearly visible and free for enough distance to complete the maneuver without interfering with traffic. Return to the authorized lane only after safely clearing the vehicle you passed.
