Prompt coordination
We gather the incident location, testing authority, required test types and employer contact so the collection plan can be confirmed quickly.
Post-accident testing in Dallas–Fort Worth
Time-sensitive testing support after a workplace or vehicle incident.
Test First helps employers coordinate DOT and Non-DOT post-accident drug and alcohol collections in Dallas and across DFW. Call immediately so we can confirm whether in-office, mobile or after-hours service is available.
After-hours service is charged separately. Confirm availability, response time, travel fees and testing requirements by phone.
What Test First provides
Professional service with clear documentation
DOT and Non-DOT support
DOT testing depends on the applicable agency rule and accident circumstances. Company-policy testing follows the employer’s lawful Non-DOT program.
Mobile DFW response
When available, a collector may travel to a workplace, terminal, job site or other suitable location across the Metroplex.
Alcohol and drug collections
Tell us whether drug testing, alcohol testing or both are required and provide the employer’s designated representative.
Chain-of-custody documentation
Accurate records help preserve specimen integrity and document who ordered, collected, handled and received the test.
Supervisor training
Employers can also enroll supervisors in reasonable-suspicion training and refreshers for better incident response and documentation.

Common questions
Answers before you visit
Does every commercial-vehicle accident require a DOT test?
No. FMCSA post-accident testing depends on factors such as a fatality, a citation and whether the incident involved qualifying injury treatment or disabling damage. The employer must apply the applicable rule.
Should the employee call or should the employer call?
The employer or designated employer representative should call whenever possible because they must identify the test authority, testing reason and result recipient.
Is mobile post-accident testing always available?
No. Availability depends on location, collector scheduling, safe access and the required test. Call immediately to confirm the available option.
Can a company require Non-DOT post-accident testing?
A company may have a lawful workplace policy requiring Non-DOT testing. That program must remain separate from DOT testing.
What if testing is delayed?
The employer should follow its applicable rule or policy, document the reason for delays and record efforts made to complete testing.
