Trucks last longer than cars
The braking distance of trucks - what you should know

How long is a truck braking distance?
For other road users, trucks can be used in road traffic threatening apparitions be. The large transport vehicles are often ten times heavier than an ordinary car. Especially in a traffic jam and trapped between two trucks drivers can feel uncomfortable. The risk of an accident is high.
To trucks adhere to persistently some conflicting rumors. on the one hand you read a lot about them Uncontrollable large machines and their long braking distance. At the same time, the statement that the The braking distance of trucks is just as long as that of cars. But where is the truth? And how can that Calculate truck braking distance? This guide takes a close look at the iron elephants.
FAQ: braking distance for trucks
In addition to the dimensions of the truck and the weather conditions, the speed in particular has an influence on the braking distance.
In principle, the braking distance for a truck is calculated in the same way as for a car. You can find out what the calculation looks like here.
The braking distance of trucks and cars in comparison
The ADAC has the braking distances of various vehicles compared and contrasted. In order to create comparable conditions, all vehicles were fully loaded and at 80 km / h to full braking forced. The result: a conventional car has one at 80 km / h Braking distance of 23.2 meters. On the other hand lies the Braking distance from the truck at 80 km / h at 36.2 meters. The distance that the 40-ton truck covers to a standstill is therefore being tested 56% longer than the braking distance of the car.
How can the braking distance of a truck be calculated?
How do you go about this when you have the Find out the braking distance of your truck want without making a practical attempt? Can be used for braking distances on trucks a formula be applied?
To answer this question, the term “Braking distance” defined more precisely become. Because this is not to be confused with the stopping distance.
- The braking distance for trucks and other vehicles is that Distance covered from the beginning of the braking process.
- The stopping distance includes additionally the response time of the driver, is therefore generally longer than the braking distance.
The braking distance for trucks is calculated using the following formula:
(Speed (v) ÷ 10) x (speed (v) ÷ 10)
This braking distance is the normal braking distance. The normal braking is opposite Emergency braking. Here is the brake pedal until it stops stepped through to regardless of the loss of control of the vehicle as quickly as possible to a standstill get. To calculate the emergency braking distance, the Normal braking value halved.
The braking distance of a truck depends on many different factors from. The above formula takes no account of that Weight of the car, still on Size, air resistance or the actual Brake performance. Finally, of course, the condition of the road surface is also of great importance, since the resistance on black ice, for example, is different from that on dry road surfaces.
The braking distance calculation of trucks in this way can therefore only be one rough guide value deliver to you do not leave in individual cases should.
What difference does the load make for the braking distance of a truck?
If you apply the above formula for the braking distance of a truck, then that remains the case Weight not taken into account. Nevertheless, the question arises: Does it make a difference to the braking distance if the Truck loaded or unloaded is?
According to ADAC, the load only plays a role in the braking distance of trucks a subordinate role, but does still a difference. A study by the “Research and Technology Center Ladungssicherung Selm GmbH” confirms this statement. The study tested, among other things, the braking distance of a 7.5 ton truck in an unloaded, properly loaded and overloaded condition. At 60 km / h the vehicle had maximum braking values of:
- 18.9 meters unloaded,
- 24.3 meters when properly loaded,
- 28.5 meters when overloaded at the rear.
In order to keep the stopping distance on the road for heavier vehicles as short as possible, there is one in Germany Compulsory equipment with automatic emergency braking assistants for trucks. The measure is a response to the increased risk that trucks pose in road traffic. Especially Rear-end collisions often have devastating consequences.
The innovation takes place in two stages. Little by little, devices designed to help reduce the impact speed are becoming mandatory. Until November 2015 in stage 1 Devices built in that determine the impact speed reduce by at least 10 km / h should. In stage 2 should reduce the impact speed by November 2018 reduced by 20 km / h can be. Although there is no direct specifications for the braking distance from trucks, but road safety should still benefit from the innovations.Were we able to help you? Then please rate us:
