A 'Steep hill' sign alerts drivers to what potential hazard?

1. Sharp curves

2. Increased stopping distance

3. Steep inclines that may require caution

4. Low visibility

The correct answer is: Steep inclines that may require caution

The 'Steep hill' sign is designed to inform drivers about the presence of a steep incline on the road ahead. This sign indicates that the road will change elevation significantly, which can present unique driving challenges. When encountering steep inclines, vehicles may need to exert more power to overcome the slope, while drivers must remain mindful of their speed and control when descending. Additionally, steep hills can lead to a loss of traction or stability, particularly in adverse weather conditions. While other hazards such as sharp curves, increased stopping distance, and low visibility may also affect driving, they are not specifically addressed by the 'Steep hill' sign. Instead, this sign focuses on the need for drivers to exercise caution due to the elevation change, ensuring that they are prepared for the physical demands placed on their vehicle and the potential for altered driving dynamics. Recognizing the specific warning of the steep hill allows drivers to adjust their speed and driving strategy accordingly, promoting safety on the road.
