If you find yourself in a new role and you're learning for the first time, read the complete DOT and FMCSA regulations at least once. The Office of Drug and Alcohol Policy and Compliance (ODAPC) is the best source for official information. Then, use this as a reference to help you solidify your understanding.

When A Driver Needs To Take A Post-Accident Test
An employee needs to take a post-accident drug and alcohol test if there is an accident that involves a death. It’s also required in accidents where one or more motor vehicles are towed from the scene or when someone is treated medically away from the scene, and a citation is issued to the CMV driver.
Type of accident involved | Citation issued to the CMV driver | Test must be performed |
i. Human fatality |
YES NO |
YES YES |
ii. Bodily injury with immediate medical treatment away from the scene |
YES NO |
YES NO |
iii. Disabling damage to any motor vehicle requiring tow away |
YES NO |
YES NO |
Reasonable-Suspicion Determination
One trained supervisor or company official can make the decision for an employee to have a drug or alcohol test. Base the decision on specific, contemporaneous, and articulable observations. This includes the appearance, behavior, speech, or body odors of the employee. Any observations of the senses (sight, hear, smell).
Pre-duty Alcohol Use
An employee cannot consume alcohol within four hours before driving.
Actions For Breath Alcohol Tests 0.02 - 0.039
If an employee has a breath alcohol concentration (BAC) between 0.02 - 0.039, they cannot drive until the next day. This includes the start of the employee’s next scheduled duty period, but not less than 24 hours following the test.
Other Alcohol Restrictions
Prohibit drivers from using alcohol for eight hours following an accident (defined above). Also, prohibit drivers from using alcohol until they've undergone a post-accident alcohol test. Choose whichever scenario comes first.
Employee Training
You must provide educational materials explaining drug and alcohol regulatory requirements. Also, they must include the employer’s policies and procedures for meeting these. Distribute these materials to the employees and make sure they’re accessible.
Supervisor Training
To make reasonable suspicion drug test determinations, supervisors need one hour of training. They also need one hour of training for alcohol test determinations.
You should have a solid understanding of the DOT and FMCSA drug and alcohol testing regulations. Remember when to drug test drivers, their alcohol restrictions, and training requirements.
