NON-DOT and DOT Testing

DOT and Non-DOT Testing: What You Need to Know

Drug and alcohol testing is an essential part of any transportation company’s drug and alcohol policy. Whether your company is subject to DOT testing or non-DOT testing, ensuring that your employees are tested in compliance with the regulations is vital to keep your operations safe and in alignment with the law. In this blog post, we will be talking about the key differences between DOT and non-DOT testing, as well as their respective requirements and best practices.

What is DOT Testing?

The U.S. Department of Transportation (DOT) regulates drug and alcohol testing for commercial drivers in the United States. It requires that all transportation companies subject to its jurisdiction have a drug and alcohol testing policy and programs that follow its strict guidelines. The DOT recognizes five types of drugs – marijuana, cocaine, opiates, amphetamines, and phencyclidine (PCP) – and alcohol use as its focus for testing. DOT modes include FAA, FMCSA, FRA, FTA, PHMSA and the US Coast Guard also follows the DOT rules and regulations.

According to DOT regulations, commercial drivers are prohibited from operating a commercial motor vehicle (CMV) if they have a prohibited substance in their system. Employers are required to test drivers pre-employment, after an accident (under certain circumstances), randomly, for reasonable suspicion, and for return-to-duty. Both urine and breath alcohol tests can be used to detect any substance.

What is Non-DOT Testing?

Non DOT testing, also known as non-regulated testing, is less strict than the DOT testing requirements. It is required by some companies, but it is not mandated by law. It is typically required for pre-employment and post-accident testing, but employers can also conduct it for a random drug test or reasonable suspicion. The tests can be done on both urine and hair samples, depending on the employer’s preference.

Non-DOT tests typically include a 5-panel or 10-panel drug test that screens for the following substances: marijuana, cocaine, opiates, amphetamines, phencyclidine, barbiturates, benzodiazepines, methadone, methaqualone, and propoxyphene. Some companies may also choose to test for additional substances such as prescription medications, over-the-counter drugs, and other illicit drugs.

Difference between DOT and Non-DOT Testing

The main difference between DOT and non-DOT testing is the legal obligation. DOT-regulated companies are mandated by law to have specific policies and procedures to comply with the regulations. Employers also need to ensure that the testing is conducted by a certified laboratory that follows DOT guidelines and is SAMHSA certified.

Non-DOT testing is voluntary, and there is no legal requirement. Employers are not required to follow specific procedures or regulations, but it is still essential for them to create a drug and alcohol policy to ensure the safety and wellbeing of their employees. Employers can choose their own labs, test timings and type of substance that can be tested.

Best Practices for DOT and Non-DOT Testing

For DOT testing, the Federal Motor Carrier Safety Administration (FMCSA) has emphasized that all registrants are required to be registered under the FMCSA Clearinghouse to access the complete commercial driver’s previous drug-program history before hiring a driver.  You must also perform annual queries each year.

Employers must also ensure regular drug and alcohol supervisor training is supplied to all supervisors who manage employees who perform safety-sensitive functions. For example, this training involves two hours of supervisor training on drug and alcohol awareness so the supervisor is able to detect and test those individuals that are under the influence of drug and alcohol.

Employers, no matter if they run a DOT-regulated or non-regulated company, should consider the following best practices to promote safety and compliance:

1. Create a clear drug and alcohol policy that adheres to either DOT or non-DOT standards.
