The Braking distance is the distance it takes from stepping on the brakes to stopping the vehicle. This means that it shows the distance in meters that the car covers during braking.
- Speed: 100 km / h
- Braking distance (normal): 100 meters
- Braking distance (emergency braking / emergency braking): 50 meters
The braking distance is the Reaction path not taken into account. It can be assumed that the reaction time between the event (suddenly occurring obstacle, etc.) and the start of the braking process is in most cases around one second. This increases the braking distance again.
For example: The formula for the reaction path gives the distance covered in meters within one second. So if you drive at a speed of 100 km / h, the response distance is 30 meters, because: (100: 10) x 3 = 30 m.
However, the formulas given above can actually only be used as Rule of thumb for calculating the braking distance apply, as the actual braking distance is highly dependent
- from the road surface,
- the condition of the road,
- from the vehicle,
- the condition of the brake,
- the condition of the tires,
- the strength of the braking,
- the loading of the vehicle.
For example, ice on the road or a bad condition of the brakes or worn tires can significantly increase the braking distance.
If the vehicle is moving at 200 km / h, the braking distance is 400 m (200 m for emergency braking).
This means: At twice the speed, the braking distance is four times as long!

Outside of built-up areas with good visibility and road conditions, the following applies: Half the speedometer in meters. So divide the speed by two that gives the distance to the next vehicle in meters. Example: A speed of 80 km / h = 40 meters distance.
In city traffic (Tempo 50) with good visibility and road conditions: Around 15 meters or three car lengths.
In case of poor visibility and road conditions outside built-up areas and in city traffic, the following applies: Double the safety distance. Out of town, this corresponds to the speedometer value. (Example: speed 80 km / h = 40 + 40 = 80 meters distance).
4Braking distance and safety distance motorcycle
This is much more difficult with a motorcycle, at least if the vehicle does not have an anti-lock braking system (ABS). And unfortunately very few motorcycles have that. The rider has two brakes, one for each wheel. Almost all of the weight is shifted to the front wheel, so the front wheel has to be braked harder than the rear. As soon as a wheel locks, the motorcycle not only starts to slip, but driving stability is also lost - a fall is practically inevitable.
That means: you brake carefully so as not to fall, and the braking distance becomes longer. In practice, the car will almost always come to a standstill earlier than the motorcycle.
5VBG driving safety training
Everyone or every employee travels a lot these days, whether on the way to work, on business trips or when transporting goods. In order to promote safe behavior in road traffic and thus reduce the number of traffic-related accidents, the VBG offers various driver training courses.
- Car driver training
- Driving safety training for young drivers up to the age of 24
- Motorcycle driving training
- Van / minibus driver training
- Bus driver training
- Bicycle driving training
Anyone who is legally or voluntarily insured with VBG can take part in driver safety training. Participation not only makes the business trip safer but also the daily commute to work and reduces the risk of an accident on the way. The participation fees are paid by the VBG.
