Pre-Employment Drug Testing
DOT regulations prohibit dispatching a driver without a verified negative pre-employment drug test. Access 3,000+ collection locations or schedule mobile testing at your location with MRO-verified results typically within 24-72 hours.
Federal law is clear: no driver may perform safety-sensitive functions until you have received a verified negative pre-employment drug test result. Dispatching a driver without this verification violates 49 CFR §382.301 and creates significant negligent hiring liability.
Diversified Drug Testing coordinates pre-employment testing through our network of over 3,000 collection locations nationwide. Applicants can test wherever is most convenient—essential for recruiting drivers across multiple states. We also offer mobile collection at your terminal or orientation site when you need multiple applicants tested simultaneously.
Our process is straightforward: we provide testing authorization, direct applicants to convenient locations with same-day scheduling, track results through MRO review to verify legitimate prescriptions, and confirm verified negative results before you clear the driver for dispatch. Consortium members receive discounted per-test pricing.

Compliance Requirements
Compliance Requirement
49 CFR §382.301 requires employers to ensure drivers receive a controlled substances test with verified negative result before the driver first performs safety-sensitive functions. A full FMCSA Clearinghouse query must also be completed. No driver may perform safety-sensitive functions until both requirements are satisfied.
