What is the minimum safety distance you should maintain from the vehicle ahead when driving at a speed of 100 km/h?

At 100 km/h, the minimum safety distance to the vehicle ahead should be 50 meters. This rule ensures you have enough space to react and brake safely if needed. An easy way to estimate this distance is that it should be about half of your current speed (in meters), so at 100 km/h, half is 50 meters. This guideline provides a safe margin in normal conditions and helps prevent rear-end collisions.
