Motor vehicle road crashes during the fourteenth and fifteenth years of life.

From a sample of 848 teenagers, 50 individuals reported a total of 52 motor vehicle road crash events: 42 involved a car, six a motorcycle, and four a bus, over a two year period. Males and females were equally represented in each type of crash. Twenty-one of the car crashes, four of the motorcycle crashes and three of the bus crashes involved injury. The injuries sustained in the motorcycle crashes were predominantly to the extremities and in the other crashes they were mainly to the head or face. On average drivers less than 25 years of age had more passengers in their cars and were involved in more nighttime crashes. A seat belt was worn in only 18 (44%) of the car crashes. A motorcycle helmet was worn in four of the six motorcycle crashes. Six (15%) crashes were reported to have involved alcohol. The main areas of risk associated with motor vehicle road crashes involving teenagers and young adults have been addressed by legislation or the graduated drivers' licensing system. An evaluation of these measures is required to establish whether they are effective.
