Mandatory vs. Optional Testing

Under federal law, jobs that involve safety or security functions generally require mandatory drug testing of applicants or employees. The U.S. Department of Transportation adopted revised regulations in August 2001, and other agencies are free to adopt their own internal regulations. Likewise, many states expressly mandate drug testing for similar jobs, for example, jobs in the medical and health related fields, jobs requiring the use of machinery or vehicles, security positions, food handling jobs, or physically demanding jobs such as utilities cable line installation or climbing.
