Screening a commercial driver is not one check with extra steps. It is five separate processes from five different sources, each with its own consent, its own timing and its own retention rule, and a carrier that treats it as an ordinary background check with a driving record attached will be missing at least two of them. This page sets out what a compliant driver file actually requires.
The five checks
First, a motor vehicle record from every state where the driver held a licence in the preceding three years. Second, a full Drug and Alcohol Clearinghouse query with the driver's specific electronic consent, before any safety-sensitive work. Third, previous employer safety performance history, which means contacting employers from the last three years about accidents and drug and alcohol violations. Fourth, the DOT physical and the medical examiner certificate. Fifth, an ordinary criminal background check where your own policy or a customer's contract requires it, which federal regulation does not.
What the DAC report is and is not
DAC is a commercial employment history database for the trucking industry, into which participating carriers report a driver's employment dates and separation information. It is a consumer report when used for employment purposes, so the FCRA applies in full, including the driver's right to dispute what a former employer put in it. It is not a government record, it is not comprehensive, and it does not replace the safety performance history investigation the regulations require. Carriers sometimes treat a DAC report as satisfying that obligation, and it does not.
Criminal history is a policy choice here
Federal motor carrier regulation does not require a criminal background check for a general commercial driving position. What it requires is the driving record, the Clearinghouse query, the safety history and the medical certification. Criminal screening is driven by your own risk policy, by customer contracts, and by specific endorsements such as hazardous materials, which carries a separate security threat assessment run by the Transportation Security Administration. Knowing which of your requirements are federal and which are yours makes the programme much easier to explain and to defend.
It is a continuing file, not a hiring event
The annual review of driving record, the driver's annual list of violations, the annual Clearinghouse query and the expiry of medical certificates all recur on their own cycles. A file that was complete at hire proves nothing two years later, and the plaintiff's first request after a serious accident is for the driver's qualification file. That is why monitoring products exist for both driving records and Clearinghouse status, and why driver qualification file management is bought as a service rather than kept in a drawer.
Questions people ask about trucking compliance
What does a DOT background check include?
Motor vehicle records from each state of licensure in the past three years, a full Clearinghouse query with the driver's electronic consent, previous employer safety performance history, and the DOT physical with its medical examiner certificate.
Is a DAC report required?
No. DAC is a commercial employment history database, a consumer report subject to the FCRA when used for hiring. It does not replace the safety performance history investigation the regulations require.
Do truck drivers need a criminal background check?
Federal motor carrier regulation does not require one for a general driving position. It is a policy or customer-contract choice, though hazardous materials endorsements carry a separate TSA security threat assessment.
How often must driver checks be repeated?
The driving record review and the driver's list of violations are annual, the Clearinghouse query is at least annual, and medical certificates expire on their own schedule, sometimes in as little as three months.
