Navigating Department of Transportation (DOT) regulations can feel overwhelming for trucking companies. Between understanding federal motor carrier safety rules and making sure each commercial driver follows every protocol, there’s a lot to manage. That’s where HDS Safety Services comes in. With over 30 years of industry experience, we help motor carriers meet—and exceed—DOT and Federal Motor Carrier Safety Administration (FMCSA) standards.
A Trusted Partner in DOT Compliance
From your first pre-employment drug test to complex DOT audits, HDS is your go-to safety partner. Our team understands that compliance isn’t just about passing inspections—it’s about building a safe, sustainable business. Whether you’re managing a fleet of vehicles over 10,001 pounds or transporting passengers across state lines, staying compliant with DOT and FMCSA regulations is critical.
HDS offers tools and support that simplify these responsibilities, so you can focus on running your business and keeping everyone safe, including the driver, the company, and the public.
Drug and Alcohol Testing: Beyond the Basics
Maintaining a drug-free workplace is one of the most important aspects of DOT compliance. All commercial motor vehicle drivers must go through pre-employment drug testing and continue to be subject to random drug and alcohol testing, post-accident testing, and return-to-duty testing under specific conditions.
HDS Safety Services operates one of Arizona’s largest drug and alcohol testing consortia. We go above and beyond federal requirements by offering non-DOT substance abuse testing options, too. This includes breath alcohol tests and urine tests customized to your company’s specific safety goals.
This level of testing ensures that drivers operating large vehicles or transporting hazardous materials are safe, focused, and legally compliant, keeping your company in good standing with the FMCSA.
Pre-Audits and DOT Audit Support
A DOT audit can feel like a big hurdle, especially if you’re unsure what to expect. HDS Safety Services reviews all critical areas, including hours of service logs, insurance documents, inspection records, and your drug testing history.
We don’t just point out areas of non-compliance—we guide you through the process of correcting them. Once you’ve made the necessary updates, we even perform a re-audit to confirm that your company is fully aligned with DOT and FMCSA regulations.
This means you can walk into any DOT inspection with full confidence.
Serving All Safety-Sensitive Industries
Whether you’re running a commercial motor carrier, managing a passenger-carrying transit service, or hiring a driver for compensation, the DOT holds your team to the highest safety standards. HDS helps ensure your drivers—CDL holders or otherwise—are properly trained, tested, and prepared for the road ahead.
From drug testing to compliance tracking, we support all safety-sensitive positions across the transportation industry.
