Maintaining a safe braking distance is crucial when driving downhill because the vehicle's weight and gravity can significantly increase speed as you descend. This means that stopping distances can become longer due to the added momentum and force acting on the vehicle. By keeping a safe distance between your vehicle and those ahead, you create more room for reaction if you need to slow down or stop suddenly. It allows for adequate time to respond to any obstacles or changes in traffic conditions without the risk of a rear-end collision. Remembering this principle helps ensure safety not just for you, but also for other drivers on the road.
