Samenvatting
The effects of a graduated licensing system (GLS) in New Zealand and the US are discussed. A project is then described which examined the effects of introducing such a system in Ontario. Ontario's GLS provides a set of restrictions for all new drivers in the first 2 years that they hold a licence. Grade 11 and 12 students with a drivers licence were asked to complete 2 questionnaires, one before and one after the introduction of GLS. Information was requested on attitudes to drinking and driving in themselves and others in addition to other aspects of driving behaviour. The results of the questionnaires are presented. The GLS appeared to have a positive effect, particularly among males.
