What is the FMCSA Clearinghouse?

The Clearinghouse is a secure online database that gives employers, the Federal Motor Carrier Safety Administration (FMCSA), State Driver Licensing Agencies (SDLAs), and State law enforcement personnel real-time information about commercial driver’s license (CDL) and commercial learner’s permit (CLP) holders’ drug and alcohol program violations. The Clearinghouse contains records of violations of drug and alcohol prohibitions in 49 CFR Part 382, Subpart B, including positive drug or alcohol test results and test refusals. When a driver completes the return-to-duty (RTD) process and follow-up testing plan, this information is also recorded in the Clearinghouse.

I am a CDL driver and I want a copy of my physical exam long form, can I have a copy?

If you are personally paying for the exam, you may have a copy. If your employer or potential employer is paying for the exam, you will need to refer to their policy regarding exam information. For personal exams and/or approved employer or potential employer exams, simply request a copy at the reception desk upon checkout.

What shows up in a drug test?

This depends on the kind of test that is being administered and the specific types of street and prescription drugs that are included.

Can you tell me the levels of drugs that are found in a person’s system?

We are not at liberty to share the exact levels of drugs found in a person’s system.

Can I get a copy of my drug test from you?

If your drug test is for personal reasons and you are responsible for payment, then you may have a copy. If your employer or potential employer is responsible for payment and has requested or required the drug test, you will need to refer to their policy regarding drug test results.

How does your random drug testing program work?

We utilize a computer software program that meets the requirements regarding random selection as outlined in the Department of Transportation's (DOT) guidelines for Drug and Alcohol Testing CFR-49 / §382.305.  The selection of participants for random drug and/or alcohol testing is created by a scientifically valid method, a computer-based algorithm and random number generator that is matched with drivers' Social Security numbers, payroll identification numbers, or other comparable identifying numbers.

What are the cut-off levels for drug testing?

Cut-off levels vary according to each state’s rules and regulations regarding drug testing. This information—as it pertains to a certain state—is available upon request.

Do you offer a DOT drug testing consortium program?

Yes. We offer local and nationwide DOT random drug testing consortium programs (C/TPA) and services for companies regulated by Federal and State government, as well as drug-free programs for non-regulated employees. In addition to serving corporations, we also specialize in providing owner-operators with their own authority and motor carriers of all sizes with convenient, cost-effective support to facilitate and manage their drug and alcohol testing compliance.
