Post-Accident Testing

Missing post-accident testing deadlines compromises insurance claims and triggers federal violations. 24/7 collector dispatch ensures you meet the 8-hour alcohol and 32-hour drug testing requirements.

When an accident occurs, the clock starts immediately. DOT regulations require alcohol testing within 8 hours and drug testing within 32 hours—missing these deadlines destroys your insurance defense and creates significant legal liability. The 2 AM accident in rural Nebraska requires immediate action, not a call to voicemail.

Diversified Drug Testing provides 24/7 emergency response for post-accident testing. Our emergency hotline is staffed by compliance specialists who immediately determine if testing is required under DOT criteria, dispatch the nearest collector from our nationwide network, and document every attempt to demonstrate "as soon as practicable" compliance.

We prepare complete incident logs for insurance claims and compliance reviews, including dispatch times, collection documentation, and chain-of-custody records. When your insurance carrier or an FMCSA investigator asks for documentation, you will have it.

Frequently Asked Questions

Post-accident testing is required when an accident involves: (1) a fatality, (2) bodily injury requiring immediate medical treatment away from the scene, or (3) disabling vehicle damage with a citation issued to the CMV driver within 8 hours. Diversified Drug Testing helps you determine if testing is required.

Collector response times vary by location, but we dispatch immediately and document all coordination efforts. In metropolitan areas, collectors typically arrive within 2 hours. Rural areas may require additional time, but every dispatch attempt is logged for compliance documentation.

DOT regulations require a written explanation when testing cannot be completed within the 8-hour alcohol or 32-hour drug window. Diversified Drug Testing prepares the required documentation, logs all dispatch attempts, and stores records for audit and insurance defense.
