We present here a few recent elements of European traffic safety research, concerning two important topics : -driver training : we will show how new theoretical models about driving behavior will produce modifications in road safety education, in initial driver training, in licensing test, in post licensing measures and more generally in lifelong learning. -influences of family environment on three aspects of young people's behaviors having a strong impact on accidents : risk taking, addiction, transgression. We propose here a developmental psychopathology model of the interactions between the various dimensions of what is a family milieu.
