Yes — that's exactly what we do. Our collector comes to your fleet yard, terminal, job site, or any location in San Diego County. No need to pull drivers off the road to visit a clinic.

FMCSA Clearinghouse
If your drivers hold a CDL, you are required to query the FMCSA Drug & Alcohol Clearinghouse before hire and annually for all current drivers. Register at clearinghouse.fmcsa.dot.gov. Not yet registered? Call us — we can point you in the right direction.
Non-compliance with 49 CFR Part 40 is not a technicality — it carries serious legal and operational consequences. DOT agencies conduct compliance audits, and violations can result in:
The FMCSA Drug and Alcohol Clearinghouse is a federal database that tracks CDL driver drug and alcohol violations nationwide. It became mandatory January 6, 2020. Here's what it means for your operation:
We coordinate directly with your TPA to ensure all required Clearinghouse reporting occurs on schedule. If you don't have a TPA, we can recommend trusted options serving San Diego County carriers.
Random testing is the DOT requirement most employers get wrong — and the most common audit failure. Here are the current minimum annual testing rates:
| DOT Agency | Drug Testing Rate | Alcohol Testing Rate | Applies To |
|---|---|---|---|
| FMCSA | 50% | 10% | CDL drivers in safety-sensitive functions |
| FAA | 25% | 10% | Aviation safety-sensitive employees |
| FRA | 25% | 10% | Railroad operating employees |
| FTA | 50% | 10% | Mass transit safety-sensitive employees |
| PHMSA | 50% | — | Pipeline and hazardous materials operators |
Random selection must be truly random — paper draws are not compliant. You must use a random number generator or a TPA with a randomization program. We can help you set this up correctly.
FMCSA regulated. Every CDL driver in a safety-sensitive function. Pre-employment, random (50%), post-accident, reasonable suspicion, return-to-duty, follow-up. Clearinghouse queries mandatory.
CDL Testing Guide →FAA regulated under 14 CFR Part 120. Applies to pilots, flight crew, ground security, and other safety-sensitive aviation roles. San Diego International Airport employers — we serve your area.
USCG regulated under 46 CFR Part 16. San Diego's Port and Navy-adjacent maritime employers must maintain compliant testing programs for all "credentialed mariners."
DOT post-accident testing has strict time limits. Missing these windows means you cannot use the test results — and FMCSA considers a missed post-accident test the same as a positive.
