Mandatory bicycle helmet use--Victoria, Australia.

On July 1, 1990, the first statewide law in Australia requiring wearing of an approved safety helmet by all bicyclists became effective in Victoria (1989 population: approximately 4.3 million) (Figure 1). Implementation of the law was preceded by a decade-long campaign to promote helmet use among the estimated 2.2 million persons who ride bicycles; the campaign included educational programs; mass media publicity; financial incentives; and efforts by professional, community, and bicycle groups (1,2). This report assesses helmet law enforcement, helmet use, and injuries related to bicycling in Victoria.
