Hire faster, without hiring risk.
Speed is the whole point
In transportation, a good driver is available for about a week. Every day your pre-employment result sits in limbo is a day a competitor can move faster. That is why we optimise this service for turnaround above everything else: same-day collection at any of 1500+ sites, and negatives typically verified within 24 hours of the lab receiving the specimen.
The rule is unambiguous — under DOT authority, a driver may not perform a safety-sensitive function until the employer has received a verified negative. Not a collection receipt. Not a lab screen. A verified negative from the MRO.
A compliant DOT hire is more than a drug test
Testing is one of four things that must happen before a CDL driver turns a wheel for you:
- Pre-employment drug test — verified negative received before the first safety-sensitive duty.
- Full FMCSA Clearinghouse query — with the driver's electronic consent given in the Clearinghouse itself, checking for unresolved violations.
- Previous employer records request — DOT testing history from all DOT-regulated employers over the previous three years.
- Driver qualification file — the surrounding paperwork that an auditor will open first.
The gap that catches carriers: a clean drug test but no Clearinghouse query. If the driver has an unresolved violation on file, putting them behind the wheel is a violation by you — regardless of how clean the test was.
When you can skip the test (and when you cannot)
DOT rules provide a narrow exception where a driver has participated in a compliant testing program within the previous 30 days and has not been out of a random pool for more than 30 days — with documented verification obtained from the prior employer. The exception is narrower than most people think, and the documentation burden is real. In practice, unless you are certain, test. It is cheaper than the finding.
Non-DOT hiring works differently
For non-safety-sensitive roles, your policy governs. Most employers make the offer contingent on a negative result and run a 5- or 10-panel screen. Some add hair testing for a 90-day lookback on senior or high-risk hires. Whatever you choose, apply it consistently to every candidate in the same role — inconsistency is what turns a routine screen into a discrimination claim.
What happens if the result is not negative
Our MRO handles the donor interview before you ever see a verified result, so a legitimate prescription is resolved confidentially and never becomes your business. If the result verifies positive, the candidate cannot perform safety-sensitive functions, the violation is reported to the Clearinghouse, and they must complete the SAP return-to-duty process before working for anyone in a DOT role. We walk you through your obligations at each point — including the referral list you are required to provide.

Pre-Employment — your questions
Collection can usually be done the same day it is ordered. Negatives are typically MRO-verified within 24 hours of the specimen reaching the laboratory. Non-negatives take 24–48 hours longer because the MRO must contact the donor first.
No. Under DOT rules a driver may not perform any safety-sensitive function until the employer has received a verified negative pre-employment result. A narrow exception exists for drivers who have recently participated in a compliant program, but it carries strict documentation requirements.
Yes. A full pre-employment query is required, and it needs the driver's electronic consent given inside the Clearinghouse itself. A clean drug test does not substitute for the query — they check different things.
DOT rules require you to obtain the applicant's drug and alcohol testing history from all DOT-regulated employers over the previous three years. IPS sends these requests, tracks the responses and files them with your hire record.
Yes, under a non-DOT program governed by your own written policy. Keep it consistent across every candidate for the same role, and keep the paperwork entirely separate from your DOT program.
They cannot perform safety-sensitive functions. The violation is reported to the FMCSA Clearinghouse, and the candidate must complete the SAP return-to-duty process before working in any DOT-regulated role. You are also required to provide them with a list of qualified SAPs. We supply that list and guide you through each obligation.
