On a hill or curve, what is the minimum distance you should be able to see ahead?

The correct answer indicates that on a hill or curve, drivers should be able to see at least one-third of a mile ahead. This distance is significant because it provides adequate visibility to anticipate and respond to any potential hazards or vehicles coming from the opposite direction. When navigating such terrains, the curvature of the road or an incline can obscure visibility, making it crucial to have a clear line of sight over a longer distance.

This one-third mile guideline is established to promote safety and ensure that drivers have enough time to react to oncoming traffic or obstacles. It allows them to make informed decisions, such as slowing down or preparing to stop, which is critical in maintaining control of the vehicle and avoiding accidents.

In contrast, shorter distances such as 100 feet or a quarter mile would not provide sufficient visibility on hills or curves, where the limited line of sight could lead to dangerous situations. This is why understanding the minimum distance required in such scenarios is essential for safe driving practices.
