Who Must Follow DOT Drug Testing Requirements?

DOT regulations require anyone operating a commercial motor vehicle (CMV) as part of their job to complete drug testing at federally specified intervals. Local employers across trucking, busing, transit, and aviation in Fairfield must meet both federal and state requirements for testing. Federal law (49 CFR Part 40) provides detailed procedures for safety-sensitive transportation employees, including those overseen by FMCSA, FAA, FTA, USCG, PHMSA, and FRA. If your business manages drivers or staff holding a CDL, you need to follow DOT testing policies to remain compliant.

Examples of organizations and employers subject to DOT regulations include:

• Commercial trucking companies managing vehicles over local or interstate routes
• Transit providers such as school bus contractors and public shuttle services
• City and county departments employing CDL holders
• Freight, coaches, and charter bus operators
• Private motor carriers operating commercial vehicles over 26,001 pounds

DOT rules require strict recordkeeping and documentation. We help Fairfield and Solano County employers prepare for routine or surprise audits by making sure every record meets DOT guidelines. Our approach gives you clarity about your obligations so you can keep every driver qualified and ready for service.

The Department of Transportation mandates drug testing for specific triggers throughout a driver’s employment. Knowing when these tests happen keeps employers and operators compliant and protects safety on the road:

• Pre-employment testing for drivers in safety-sensitive positions before they can start work
• Random drug testing performed at regular intervals throughout the year
• Post-accident testing after particular incidents involving a CMV
• Reasonable suspicion testing based on trained supervisor observations
• Return-to-duty and follow-up testing required after policy violations or failed tests
