When overtaking and passing another vehicle on a two-lane road, when is it safe to get back into the right lane?

• A. When you can see the overtaken car in your rearview mirror
• B. After you pass the other vehicle by two car lengths
• C. When you are back to the same speed as traffic
• D. When you reach the opposite lane

Answer: (A)

When you overtake on a two-lane road, you should only move back into the right lane once you can see the vehicle you just passed in your rearview mirror. This cue confirms the overtaken car is fully behind you and there’s a safe gap, so you’re not cutting them off if they speed up or if your distance shrinks. Relying on a rough two-car-length rule isn’t reliable because it depends on speed, road, and vehicle length. Returning when you’re at the same speed as traffic doesn’t guarantee a safe gap behind you, and waiting until you reach the opposite lane would put you in the oncoming lane, which is dangerous and not lawful on a two-lane road.
