During the 1990s there was a shift in driver training in Sweden from a "skill oriented" content, with the focus on improving driving skill to handle critical situations, towards a "insight oriented" content, with the focus on avoiding critical situations through larger safety margins. There was also a discussion of the advantages and drawbacks of each strategy. The overall aim of the study is to compare two driver-training strategies for young driver, "insight oriented" training and "skill oriented" training. The comparison was done in three substudies. The presentation will focus on the substudy that evaluates the effect on the driving style in real traffic among young drivers. Data were collected unobtrusively by an instrumented car. The project has an experimental design, with two test groups and one control group, comprising a total of 48 young men. About two months before the data collection, both test groups had undergone a day of driver training with either a "skill oriented" or "insight oriented" content. The results indicate negative effects of the skill-oriented training on driving style in real traffic. The conclusion of the project is however that neither of the two training strategies showed any positive traffic safety effects. The project suggests that driver training for young drivers should be "insight-oriented" to motivate the use of large safety margins but also increase skills in how to avoid critical situations in traffic.
