What You Should Know About DOT Drug and Alcohol Training Requirements

DOT companies are mandated by federal regulations to provide DOT-compliant drug and alcohol training to all employees. However, those requirements vary from one area of the company to another. It’s essential to understand DOT drug and alcohol training requirements as they apply to the different areas of your business. Who should get which type of training? How long should such training last? What are the various training program types available? These are just a few of the questions you must answer.


All transportation company supervisors are required by law to undergo 120 minutes of drug and alcohol training. These courses are split, with half focusing on controlled substances and a half on alcohol use in the workplace. Key components of these courses include learning how to enforce the company’s policy regarding drugs and alcohol, how to identify potential users in the workplace, provide testing for those individuals, and then offering assistance to those who test positive.

General Employees

Most DOT companies will also have to provide training for general employees that meets DOT drug and alcohol training requirements. These courses are generally shorter in duration than the programs designed for supervisors but are no less vital. They’re designed to help employees understand the ramifications of drug and alcohol abuse in the workplace on their personal and professional lives, as well as their health and well-being.

Tailored to Your Sector

It’s vital to understand that DOT drug and alcohol training requirements vary from one industry sector to another. For instance, FAA-regulated companies face one set of requirements, while bus companies must comply with another set. It is essential that you choose a training provider capable of delivering courses that meet the governmental regulations for your specific industry segment, as there is no “blanket” course applicable to all industries.

For Substance Abuse Professionals

Substance abuse professionals must also comply with government regulations. These vary significantly from those that apply to transportation companies. DOT drug and alcohol training requirements for substance abuse professionals ensure that the completion of a qualifying course prepares the professional for government-mandated tests prior to certification to work in the field.

By ensuring that your company provides courses to employees that meet or exceed DOT drug and alcohol training requirements, you do more than ensure compliance. You create a safer environment for employees, supervisors, and, ultimately, your customers.
