[Responsibility in the prevention of accidents of the most exposed pedestrians: children and elderly persons].

A study has been carried out on the Swiss road accidents statistics involving pedestrians. The most exposed road users (young and aged pedestrians) are the ones best protected by traffic law. However, data suggest that these pedestrians are more frequently declared responsible for the accidents in which they are involved. Arising from this contradiction, both the notion of responsibility and the way the prevention of these accidents is conceived should be queried.
