Many roles in the transportation industry involve significant responsibility, potentially affecting the safety of thousands of passengers and motorists. To minimize the risk of mistakes caused by drug or alcohol abuse, the Department of Transportation (DOT) requires employees in safety-sensitive fields to undergo regular drug testing as a condition of employment. If you own a regulated business or hope to work in the transportation industry, here’s some important information about DOT testing.

What You Should Know About DOT Testing

Which employees are subject to DOT testing?

Any position that could impact the safety of passengers or drivers on the road is likely to require regular drug testing. This includes school bus drivers, airplane mechanics, subway operators, ship captains, and truckers, among others.

What substances do DOT tests look for?

All DOT tests use the same protocol. They test for traces of marijuana, cocaine, amphetamines, opioids, and PCP. However, individual employers may test for additional substances according to their company policies.

When is DOT testing required?

In addition to pre-employment, DOT-regulated employees must also submit to testing if they’re suspected of using illegal substances or within eight hours of a workplace accident. You must also submit to random testing on a quarterly basis. Also, you’ll have to pass another test before returning to work if your results came back positive.

What happens if I fail a DOT drug test?

If an employee fails a drug test, their employer is required to immediately remove them from any roles that could impact public safety. You may also be temporarily suspended, terminated, or stripped of industry licenses or certifications.
