Old vs. new truck: Which of them has better brakes?

Commercial vehicles are becoming safer – not only because of modern assistance systems. Also the braking performance has improved significantly in recent years. A test conducted by DEKRA Accident Research shows how much braking distance can be saved by new technologies.

Even though the media often reports heavy accidents involving trucks, the actual number of accidents is declining. For example in Germany: according to the Federal Statistical Office, the number of accidents with personal injury involving commercial vehicles declined by 20 percent between 2005 and 2016.

Among other things, this is due to the continuous development of vehicle technology.
A test by DEKRA accident research demonstrates how roads are made safer by modern technologies: In a brake test, they compared the braking performance of a modern semitrailer tractor with a 20 year older model. For that they accelerated the trucks to 80 km/h – then they stopped both vehicles simultaneously. The video shows the results of the test.
