Does CRST International Drug Test?

Drug Testing by Position

DOT-Mandated Testing for All CRST Drivers

CRST International is a major truckload carrier known particularly for its team driving operations. All driving positions are DOT-regulated safety-sensitive roles subject to mandatory drug testing under 49 CFR Part 40. DOT testing requires a standard 5-panel urine test screening for marijuana (THC), cocaine, opioids, amphetamines, and PCP. Testing occurs pre-employment, randomly (at least 25% of drivers annually for drugs), after DOT-reportable accidents, upon reasonable suspicion, and before returning to duty after a violation. Federal DOT requirements override all state marijuana laws.

CRST's CDL Training Program and Drug Testing

CRST operates a paid CDL training program that provides free training to aspiring truck drivers in exchange for a commitment to drive for CRST for a specified period. Drug testing occurs before training begins — all applicants must pass a DOT urine drug test before they can start the training program. Failing the test disqualifies you from the program. The DOT test includes marijuana screening regardless of state law. Prospective trainees should ensure they are drug-free before applying to the program.

CRST's Drug-Free Workplace Policy

CRST maintains a strict drug-free workplace policy across all of its divisions. The company has zero tolerance for drug and alcohol use that affects safety or job performance. All employees are subject to post-accident testing if involved in a workplace incident and reasonable-suspicion testing when observed signs of impairment are present. CRST participates in the FMCSA Drug & Alcohol Clearinghouse and conducts pre-employment and annual queries on all drivers to check for prior violations.
