Final answer:
Prior to the crest of a hill, it is important to be in the center portion of the lane for better visibility and safety.
Step-by-step explanation:
Prior to the crest of a hill, it is important for a driver to be in the center portion of the lane. This ensures that the driver has the best visibility and is able to react to any potential hazards or oncoming traffic.
Being in the center portion of the lane allows the driver to have a clear line of sight over the hill, making it easier to anticipate any obstacles or vehicles approaching from the other side. It also allows for a wider margin of safety, as it keeps the car away from the edges of the road where there may be drop-offs or uneven surfaces.
By staying in the center portion of the lane, the driver maintains control and can adjust their position as needed to safely navigate the hill.
