Post-Accident Testing
When an accident happens, the clock starts: DOT requires alcohol testing within 8 hours and drug testing within 32 (49 CFR 382.303). Our 24/7 dispatch and our own collectors across Nebraska and Kansas get a driver tested — and every attempt documented — so you meet the window and stay defensible.
DOT post-accident testing must happen within strict windows after a qualifying crash — 8 hours for alcohol, 32 hours for drugs (49 CFR 382.303). We dispatch collectors 24/7 and help your DER make the qualification call.
When an accident occurs, the clock starts immediately — and a missed testing deadline can undermine your insurance defense and put you in violation. DOT gives you 8 hours for alcohol and 32 hours for drugs (49 CFR 382.303). A 2 a.m. accident on a rural highway needs a collector, not a voicemail.
Answer first: is a test even required?
Not every accident triggers a DOT test — and testing when you shouldn't, or failing to when you must, both create problems. Our team helps your DER make the call against the 382.303 criteria before the clock runs out: a fatality; or a citation for a moving violation plus an injury treated away from the scene; or a citation plus a vehicle towed or disabled.
Our collectors, dispatched around the clock
When a test is required, we dispatch — 24/7. Our own collectors are located across Nebraska and Kansas, with a nationwide partner network as backup for out-of-area events, so a driver gets tested near the scene instead of racing across the state.
Documented to defend you
We document every step — the accident-qualification determination, the dispatch, and every attempt to test as soon as practicable — so if a window can't be met despite best efforts, you have the record DOT and your insurer will ask for. Collections follow Part 40; drug results are MRO-verified.

Compliance Requirements
Compliance Requirement
When a post-accident test is required — 49 CFR 382.303
A DOT post-accident test is required when the accident involves a human fatality; or the driver receives a citation for a moving violation and a person is injured and receives immediate medical treatment away from the scene; or the driver receives a citation for a moving violation and a vehicle is towed or disabled.
The windows
Alcohol testing must be conducted within 8 hours — attempted within 2, with a written explanation if it isn't completed within 8. Drug testing must be conducted within 32 hours. Testing must be done as soon as practicable, and the employer must document any delay.
Part 40 and MRO
All collections follow 49 CFR Part 40, and every non-negative drug result is reviewed by a Medical Review Officer before it is reported.
Frequently Asked Questions
