DOT requires a drug & alcohol testing program — random pools, pre-employment tests, and records — and gaps mean out-of-service drivers and audit failures. Simplex runs your consortium and testing program end to end.
Carriers of every size rely on us to stay compliant and rolling.
A quarter-century through every FMCSA rule change.
Filings, records, monitoring, and audits — all under one roof.
Every angle of compliance watched, so nothing slips.
Consortium enrollment, random pools, and testing logistics — we run your DOT drug & alcohol program so you stay compliant.
We enroll your operation in a compliant random testing consortium.
Random drug and alcohol selections managed and documented all year.
Every new driver tested before they drive, with results on file.
The right test ordered fast when an accident or suspicion requires it.
Your written policy and testing records built and kept audit-ready.
Testing results coordinated with your Clearinghouse reporting.
A missed random selection or a lost record can fail an audit and sideline drivers. For 25 years we've managed DOT drug & alcohol programs — random pools, testing, and records kept audit-ready.
We track deadlines, scores, and violations continuously — not just at renewal.
One specialist who knows your operation by name, start to finish.
Plain-English answers on exactly what you need, and when.
We catch issues early, before they reach an audit or an Out-of-Service order.
Every document and due date kept in order and ready when you need it.
We stay with you all year — for every requirement, not just audits.
"I've been using Simplex for almost a year now, and I'm very happy with the service they've provided. A month ago, I had my audit, and I couldn't have asked for better help than what Ms. Catherine Games provided. She helped me understand the entire process and assisted me in gathering all the information requested by the officer. From day one, she was very kind until the completion of my audit, which was a success."
"Simplex has been taking care of my company for quite some time now and they're a dream to work with. They do everything for you so you're not worried about if your company is missing something and they're very thorough. In the audit process, Hansey Reyes is the best! She makes sure all documents are uploaded on time and she's very knowledgeable about it so she can offer good advice in the event you have problems in any of the areas DOT looks at."
"Simplex have been very beneficial to our company and we appreciate everything they have done to maintain us in compliance all the time! Special thanks to SAM Christianne Espinoza and Lilian Medina, as they have been the key to our success!"
