What is the requirement when passing another vehicle on a two-lane road?

When passing another vehicle on a two-lane road, the requirement is to see both headlights of the vehicle you passed in your rear-view mirror. This confirmation ensures that you have safely cleared the passing lane and that there is adequate distance between your vehicle and the one you just overtook.

By checking that both headlights are no longer visible, you can ascertain that the vehicle is far enough behind you, minimizing the risk of a collision, particularly if the road is narrow or if the vehicle you’ve passed accelerates quickly. This practice also reinforces safe driving habits as it acknowledges that visibility and distance are key factors in safe driving maneuvers, particularly in potentially hazardous situations like passing another vehicle.

Other options might present considerations important for safe driving, but they do not fully encapsulate the critical requirement of verifying that the lane is clear after overtaking before merging back into your lane.
