Samenvatting
The overall highway fatality rate has dropped almost conti- nuously since 1925, from 20 to 2.5 per 100 million miles of travel in 1984. Still, the almost 44000 fatalities in 1984 can and will be decreased. The greatest number of combi- nation truck accidents takes place on two- lane rural roads. Single- vehicle accidents are responsible for 70 percent of heavy truck occupant fatalities. Doubles and heavier trucks appear to be as safe as other heavy trucks. Rollover and ejection are responsible for the greatest number of truck occupant fatalities.
