Which of the following can lead to increased braking distance?

Driving at speed without considering road conditions can significantly increase braking distance due to several factors. When a vehicle is traveling at high speeds, the momentum increases, which means that more force is needed to bring the vehicle to a stop. This becomes especially critical if the road conditions are poor, such as when there are wet, icy, or gravel surfaces, as these can impair traction and reduce the effectiveness of the brakes.

Additionally, if a driver does not adjust their speed based on the road conditions, they may not allow for sufficient stopping distance, leading to the risk of a collision. A driver should always be aware of their surroundings and adjust their speed accordingly to ensure they can stop safely.

Engaging cruise control on flat roads or maintaining a constant speed might not directly affect braking distance, as they typically provide a stable driving condition. Using low gears when descending can actually help control speed and may reduce the need for heavy braking, thus potentially decreasing braking distance under those circumstances.
