Abstract
"On the job" motor vehicle deaths number more than 4000 annually in the U.S. and comprise nearly one-third of all work-related deaths. Yet there are no standards relating to on-the-road safety of the millions of workers whose jobs entail large amounts of driving, and U.S. standards affecting occupational safety cover only drivers in interstate commerce. Drivers of some commercial vehicles, such as heavy trucks, are at special risk of injury. The need for better protection of this large population of highrisk workers is illustrated.
