For higher speeds up to about 100km/h outside built-up areas a similarly defined 2-second rule applies, which for 100km/h translates to about 50m. For speeds on the order of 100km/h there is also the more or less equivalent rule that the stopping distance be the speed divided by 2 k/h, referred to as halber tacho (half the speedometer) rule, e.g. The braking distance is the distance it takes for your vehicle to come to a complete stop when you apply the brakes.
