What We Do

Full-Spectrum DOT
Compliance Services

Every service your fleet needs to stay compliant with FMCSA drug and alcohol testing regulations — managed by certified professionals.

01
Pre-Employment Testing
Required before any CDL driver gets behind the wheel. We schedule, collect, and report — same-day turnaround available.
02
Random Pool Management
We enroll your drivers in our federally compliant random consortium, run quarterly draws, and notify you the same day a driver is selected.
03
Post-Accident Testing
Available on-call for rapid response. DOT requires testing within 8 hours for alcohol and 32 hours for controlled substances after qualifying accidents.
04
Breath Alcohol Testing
Certified BAT-administered testing using DOT-approved evidential breath testing devices. Valid for all FMCSA alcohol testing requirements.
05
Clearinghouse Reporting
We manage your FMCSA Clearinghouse account — reporting violations, running required queries, and keeping your records audit-ready at all times.
06
Return-to-Duty Program
We coordinate the full RTD process after a violation — SAP referral, observed testing, and the required follow-up testing schedule.
