Abstract
The testing of the driving data-recorder in a Europe wide field test in private cars and in private driving should help the utilisation and optimisation of new car safety technologies in the field of road traffic safety. Priority is given to improving the safety of the highest risk group, "young drivers" (aged 18-25 years). The objective is to reduce accidents by means of the black box and the effect it has on the driver. Furthermore, the driving data-recorder can contribute to a more precise and objective understanding of traffic accidents and, thereby, to a reduction of those accidents, and their consequences and costs.
