Determining standards of care for substance abuse and alcohol use in long-haul truck drivers.

The trucking industry employs approximately 9 million workers, with approximately 3 million being long-haul truck drivers. Truck drivers are exposed to a variety of stressful situations, such as working long hours, no sleep, inadequate rest and relaxation, being away from home and support systems, and driving in hazardous conditions. These risk factors place the long-haul truck driver at an increased risk for possible use or abuse of alcohol and drugs. Identification of those at risk and those who are abusing alcohol and drugs is vitally important for the health of these truckers.
