Understanding stopping distances is crucial for road safety. This involves thinking time, reaction time, and braking time. The two-second rule is a simple way to maintain a safe following distance on dry roads, which should be doubled in wet conditions and significantly increased on slippery surfaces. At 120 km/h, a car travels over 33 metres per second, meaning even with an optimal one-second reaction, you’ve covered a significant distance before braking. The article highlights how inadequate following distances at speed, especially on motorways, drastically increase the risk of fatal collisions. Factors like driver alertness, vehicle condition, and road conditions all impact these critical distances. If you find a vehicle too close behind you, it’s safer to gently reduce your speed or change lanes, rather than reacting aggressively.
