Accredited DOT Testing Solutions

If your business requires employees with commercial driver's licenses (CDLs), it is imperative that you maintain compliance with DOT regulations set by FMCSA. These regulations stipulate that CDL holders must undergo regular drug and alcohol testing, including urine and breathalyzer tests, to ensure their safety and the safety of those around them.

At Foxx Laboratories and Screening®, we offer a comprehensive selection of certified DOT testing services that meet FMCSA's strict standards. Our labs adhere to these regulations, and our staff is well-versed in proper testing procedures and techniques. Our Fastest Labs collectors are certified Breath Alcohol Technicians (BATs) and Certified Lifeloc Operator and Calibration Technicians (C-LOCTs). Whether you require random DOT drug testing, a post-accident breathalyzer test, or return-to-duty testing, our team of friendly and professional experts can assist you.

Under FMCSA regulations, it is mandatory for businesses employing CDL-holding drivers to conduct regular drug and alcohol testing. This applies to a range of entities, including for-hire motor carriers, private motor carriers, governments (Federal, State, and local), civic organizations, churches, and anyone who owns, leases, or assigns drivers to operate commercial vehicles. This also extends to employees of organizations governed by FAA, FRA, FMSCA, PHMSA, FTA, and USCG. As an employer, it is your responsibility to ensure that DOT testing is conducted as required and that your employees are DOT compliant. At Fastest Labs, we provide a range of solutions to help you meet these stringent regulations.
