Question

Visibility v. Speed: (Hills, Curves) Whenever you come to a hill or curve where you

cannot see over or around, ___ your speed so you can ___ if necessary.

Answer 1

When approaching a hill or curve with limited visibility, reducing your speed is necessary to safely react and stop for any potential hazards.

Step-by-step explanation:

Whenever you come to a hill or curve where you cannot see over or around, it is critical to reduce your speed so you can stop if necessary. This principle is essential for maintaining safety on the road, as limited visibility increases the risk of accidents. In scenarios where visibility is compromised, such as hills and curves, the ability to react to unforeseen obstacles or conditions is heavily dependent on speed. If a car goes over the top at faster than this speed, the likelihood of not being able to stop in time for an obstacle increases. Conversely, if a car goes over the top at slower than this speed, the driver has a better chance of reacting and stopping if an obstacle is present. Race car drivers understand this balance as depicted in Figure 6.32, which shows that cutting the corner allows them to maintain higher speeds safely when visibility is not an issue. However, on public roads where conditions and traffic are less predictable, the emphasis is always on safety first, which means adjusting your speed to the level of visibility.
