Accident after emergency braking for no reason: Is it really always the person driving behind you who is to blame?. In traffic, it is important to maintain the correct distance from the vehicle in front.
Outside of town, the rule of thumb is “half the speedometer’ - meaning that at a speed of 100 km/h on the country road you have to keep a distance of at least 50 meters. There is no exact specification in meters as to how large a distance must be in road traffic in the Road Traffic Act.
