DOT drug testing is federally regulated testing required for employees in safety-sensitive transportation roles. Testing must follow strict chain-of-custody procedures, identity verification, and DOT-approved collection methods.

DOT testing may be required for:

• Pre-employment testing

• Random drug testing

• Post-accident testing

• Reasonable suspicion testing

• Return-to-duty testing

• Follow-up testing

All DOT drug tests are processed through DOT-certified laboratories and reviewed by a Medical Review Officer (MRO) when required.
