This study revealed a significant decrease in mortality from injuries sustained by motorcycle accidents following the decree promulgated in 1992 for compulsory use of safety helmets by motorcyclists and pillion riders. The helmets can help only in protection of head injury but do not affect the number of accidents. This safety device can not protect any serious injuries of the neck, chest or internal organs which could result in death or permanent disability. To gain maximum benefit from the law, the helmets should be of standard specification and worn properly. Education to drivers and pillion riders particularly male adolescents is essential in reducing the incidence of motorcycle accidents.
