Abstract
Legislation on seat belts and crash helmets has been introduced since 1975. Safety belts are used by 50-75% of car drivers and passengers. Crash helmets are used by virtually all motorcyclists and moped riders. Fatalities have been reduced due to the use of seat belts by 60%, and due to the helmets by 40%. The number of fatalities and injured still decreases, for which there is no apparent reason.
