Accident examples, Germany

Apr 2016

Crash test
Traveling at 80 km/h, and without braking, a Jeep Grand Cherokee (passenger car) collides with three stationary cars, which represent the back of a traffic jam. The assumption is that the Jeep driver was distracted and so did not see the back of a traffic jam ahead.

Vehicles (passenger cars)
Jeep Grand Cherokee
Renault Twingo
Chrysler Voyager
Peugeot 106

Cause/problem
The driver of the Jeep does not see the back of a traffic jam ahead.

Consequences/injuries
The occupants of all the cars involved would be exposed to a more or less severe risk of injury. The occupants of the Renault Twingo in particular – both in the rear and front seats – would have had little chance of survival.

Avoidance measures, mitigation of consequences/
strategy for road safety measures

Such an accident could have been avoided were the driver paying attention. Also, state-of-the-art driver assistance systems such as automatic brake assist, which warns the driver and, in critical situations, initiates a braking operation, could either prevent the accident altogether or significantly mitigate the consequences.
