What should you do when driving along sharp curves and steep hills?

When navigating sharp curves and steep hills, it is vital to apply all of the strategies outlined in the correct answer. Using a lower gear while going down long steep hills is crucial because it helps control your vehicle's speed, preventing it from gaining excessive momentum that could lead to loss of control. This is especially important on steep descents where brakes can overheat and fail if they are used continuously.

Additionally, allowing an approaching vehicle at least half of the paved surface is important for safety when driving through narrow areas. It ensures that there is enough space for both vehicles to pass without the risk of colliding, particularly on roads where visibility might be limited due to the curve or steep incline.

Staying close to the right edge of the road also enhances safety by helping to position your vehicle away from oncoming traffic and making it easier to navigate turns without crossing into the path of other vehicles. This practice is especially beneficial on curves where visibility is restricted.

All these actions combined create a comprehensive approach to safely handling driving situations that involve sharp curves and steep hills, emphasizing careful speed control, spatial awareness, and proper positioning on the roadway.
