What Are the DOT Post Accident Drug Testing Requirements?
Driving a commercial motor vehicle under the influence of drugs or alcohol is a severe federal offense. To combat impaired driving, the Federal Motor Carrier Safety Administration (FMCSA) mandates strict testing protocols for CDL holders following a crash.
Whether you are a victim trying to prove the truck driver was intoxicated, or a CDL driver trying to protect your license from an unjust termination, you must clearly understand what the DOT post accident drug testing requirements are.
A drug and alcohol test is not required for every minor fender bender. Under federal law, the trucking company is legally obligated to test the driver only if the crash meets specific severity thresholds, such as a fatality, or if the driver receives a moving violation citation in connection with a tow-away or injury-producing crash.
When is the Test Mandatory?
A trucking employer must administer a DOT-regulated post-accident test if any of the following occur:
If a crash results in a human fatality, the surviving truck driver must be tested immediately, regardless of whether they were issued a citation or who was at fault.
If anyone requires immediate medical treatment away from the scene (e.g., an ambulance ride to the hospital) AND the truck driver is issued a citation by police, testing is mandatory.
If one or more vehicles must be towed from the scene due to disabling damage AND the truck driver is issued a citation, testing is mandatory.
The Ticking Clock
Time is of the essence. The trucking company must conduct an alcohol test within 2 to 8 hours of the crash, and a drug panel (urine test) within 32 hours. If a motor carrier fails to test their driver within these strict timeframes, a personal injury attorney can use this failure to argue corporate negligence and a cover-up.
