Although road accidents account for about 17% of hospital emergencies, they are the third commonest cause of death. Polytrauma is the main cause of death below the age of 40 years. Legislative action and safety measures (i.e. speed restriction, safety belts, safety helmets) and improvement in the hospital emergency care system in Germany resulted in a continuous reduction in road accident victims from about 19,000 in 1979 to about 12,000 in 1983. Additionally, the fall in personal injury resulted in savings of about 7,900 DM (US $3,000) in cases of minor injury, 79,000 DM (30,000 US$) in cases of severe injury and about 685,000 DM (280,000 US$) in cases where lives were saved.
