When approaching a hillcrest where you cannot see the other side, what is the recommended way to approach?

Answer: A — In the rightmost lane.

When approaching a hillcrest where visibility is limited, the recommended approach is to travel in the rightmost lane. This position allows you to remain as far to the right as possible, which is a general safety principle when navigating areas where your line of sight is impaired. Being in the rightmost lane also positions you closer to the edge of the roadway, potentially avoiding collisions with vehicles that might be coming over the crest from the opposite direction. Additionally, driving in the rightmost lane allows for quicker access to the shoulder or side of the road if an emergency arises, providing a safer option than being in a lane that could place you in direct conflict with oncoming traffic. It is important to maintain a cautious speed to ensure that you can react properly if an unexpected situation arises as you crest the hill.
