Samenvatting
An evaluation study made of the motorcycle graded licence scheme introduced in Western Australia in March 1973, is described. As a result of the licence scheme persons who passed their road test on a motorcycle with an engine capacity up to 250 cc. were only permitted to ride motorcycles of the same maximum engine capacity. It is concluded that the introduction of the graded licence scheme did not effect a statistically significant reduction in the incidence of motorcycle accidents in Western Australia.
