Pre-Employment Drug Testing

A driver can't perform safety-sensitive functions until you have a verified negative pre-employment drug test (49 CFR 382.301). Test at our clinics, on-site with our mobile collectors across Nebraska and Kansas, or at a partner site nationwide. MRO-verified. $75 clinic / $95 mobile.

DOT pre-employment drug testing is required before a driver first performs safety-sensitive functions (49 CFR 382.301). We test at our Nebraska clinics, on-site, or nationwide — MRO-verified and Clearinghouse-coordinated.

Federal law is unambiguous: no driver may perform safety-sensitive functions until you have a verified negative pre-employment drug test result. Dispatch a driver without it and you've violated 49 CFR §382.301 — and taken on real negligent-hiring exposure.

Three ways to get it done

Test the way that fits the hire: at one of our clinics in Lincoln, Beatrice, or West Omaha; on-site with our own mobile collectors across Nebraska and Kansas when you're onboarding a group; or at a partner collection site anywhere in the country when you're recruiting a driver from out of the area. However it's collected, it runs through the same compliant process.

Compliant, MRO-verified, documented

DOT pre-employment tests are laboratory-based and follow 49 CFR Part 40 — chain of custody, lab analysis, and review by a qualified Medical Review Officer before any result is reported. You get a clear negative verification for the driver's qualification file, typically within 24–72 hours.

Don't forget the Clearinghouse

For CDL drivers, DOT also requires a pre-employment FMCSA Clearinghouse full query before the driver performs safety-sensitive functions. As your C/TPA, we coordinate the query alongside the test, so nothing gets missed at onboarding.

Non-DOT hiring, too

Testing a non-regulated new hire? We run non-DOT panels — from a 4-panel to a 10-panel, instant or lab-confirmed — matched to your policy.

Compliance Requirements

Compliance Requirement

The rule — 49 CFR 382.301

An employer must receive a verified negative controlled-substances test result before permitting a CDL driver to perform any safety-sensitive function. There is no grace period and no conditional start on a DOT pre-employment drug test.

The Clearinghouse query — 49 CFR 382.701

Before a CDL driver performs safety-sensitive functions, the employer must also run a pre-employment FMCSA Clearinghouse full query — with the driver's consent — and confirm the driver is not in a prohibited status.

Part 40 process

The test is collected and handled under 49 CFR Part 40 and verified by a Medical Review Officer before the result is reported.
