About this service
What is DOT post-accident testing?
A mandatory drug and alcohol test required following a qualifying accident involving a commercial motor vehicle, governed by 49 CFR Part 382 (FMCSA) and 49 CFR Part 40 (collection procedures).
It is one of the six required test types under the DOT’s drug and alcohol testing program. The purpose is to determine whether drug or alcohol use played a role in the accident.
Unlike other DOT test types, post-accident testing has strict time windows that begin from the moment of the accident. Missing these windows can result in a failed test being recorded as if the driver refused, a serious DOT violation. Speed of response and proper documentation are both critical from the moment an accident occurs.
The clock starts at the time of the accident, not when you call us. Alcohol testing should begin as soon as practicable and must occur within 8 hours. Drug testing must occur within 32 hours. If either window expires you must document why testing did not occur, and the failure to test may be treated as a refusal in some circumstances. Call (816) 442-0295 immediately after a qualifying accident.

When testing is required
The three conditions that require post-accident testing
Under FMCSA regulations (49 CFR 382.303), post-accident testing is required when any of the following three conditions are met.
Condition 1: fatality, always required, no citation needed
If the accident results in the loss of human life, any human life, all surviving drivers who were operating a commercial motor vehicle involved in the accident are subject to post-accident drug and alcohol testing. No citation is required for testing to be triggered. This is the most clear-cut condition.
Condition 2: bodily injury requiring off-scene treatment, citation also required
If any person involved in the accident is injured and requires immediate medical treatment away from the scene, and the CMV driver receives a citation for a moving traffic violation arising from the accident, post-accident testing is required. Both conditions must be present.
Condition 3: disabling vehicle damage requiring a tow, citation also required
If any motor vehicle involved in the accident incurs disabling damage and must be transported away from the scene by a tow truck or other vehicle, and the CMV driver receives a citation for a moving traffic violation arising from the accident, post-accident testing is required. Both the tow and the citation must be present.
If an accident does not meet any of the three conditions above, DOT post-accident testing is not required. However, employers should document the accident, the assessment of whether testing was required, and the reasoning for not testing. This documentation protects the employer during DOT audits and demonstrates a properly managed compliance programme.
Step-by-step process
What happens after a qualifying accident
Every step counts. The actions taken in the minutes and hours following an accident determine whether your company remains in compliance.
Call us immediately, (816) 442-0295
The moment you determine that a qualifying accident has occurred, or even that one may have occurred, call us. Tell us the time of the accident and what happened. We will confirm whether it triggers testing, advise on the current status of your time windows and get you scheduled immediately. Do not wait to determine whether testing is required before calling.
Notify the driver and restrict alcohol consumption
Notify the driver of the requirement for post-accident testing as soon as possible. The driver must not consume alcohol from the time of the accident until testing is complete, or for at least 8 hours after the accident, or until tested. If a driver consumes alcohol before testing, it complicates the result and may be treated as a refusal. Document this notification with a timestamp.
Document the accident circumstances immediately
While waiting for testing, document everything: the time and location of the accident, whether a fatality occurred, whether any vehicle was towed, whether any person received off-scene medical treatment, whether the driver received a citation, and all contacts made regarding testing. This contemporaneous documentation is critical for regulatory and legal purposes.
Complete breath alcohol testing (BAT)
Alcohol testing must be conducted using an evidential breath testing device operated by a certified Breath Alcohol Technician. We use DOT-approved certified equipment and follow 49 CFR Part 40 procedures. Results are immediate, the BAT reading is your result.
Complete the DOT 5-panel urine drug test
The urine specimen is collected following strict 49 CFR Part 40 chain-of-custody procedures, sealed, labelled and sent to a SAMHSA-certified laboratory. Negative results typically return within 24–48 hours. Non-negative results require confirmatory testing and MRO review before a final result is issued. See the DOT 5 panel.
Retain documentation and report to the Clearinghouse if required
Retain all testing documentation per DOT records retention requirements: 5 years for positive results and refusals. If the driver receives a verified positive drug result, a confirmed alcohol result of 0.04 or above, or refuses testing, the violation must be reported to the FMCSA Drug and Alcohol Clearinghouse within 3 business days.
