Post-Accident Drug Testing: Questions Employers Should Ask First

Published August 25, 2026

Before ordering a post-accident drug test, employers should identify the rule or policy that applies, document the event, and act promptly.

After a workplace or vehicle accident, employers often want to arrange testing immediately. Speed matters, but so does ordering the correct type of test for the correct reason.

Is this a DOT-regulated event?

If the employee performs DOT-regulated safety-sensitive duties, first determine whether the applicable agency’s post-accident testing criteria are met. Do not label a test as DOT simply because a commercial vehicle was involved.

Does company policy require a Non-DOT test?

For employees who are not covered by a DOT post-accident requirement, the employer’s written workplace policy may still call for testing. Review the policy and applicable state or local law before proceeding.

What information should be documented?

Record the date and time of the incident, the employee involved, the reason testing is being requested, who made the determination, and the collection arrangements. For regulated events, follow the specific documentation requirements that apply.

Avoid unnecessary delay

Once the decision to test has been properly made, coordinate the collection promptly. Provide the employee with clear instructions and make sure the collection site receives the correct test reason and employer information.
