How Long Does DOT Drug and Alcohol Training Last?

Transpiration companies are required to comply with Department of Transportation mandates in terms DOT drug and alcohol training. However, many companies aren’t completely sure what this training is, how long it should take or who is required to complete the program. Given the important role of safety-sensitive employees within these companies, it is essential to have a firm understanding of the regulations and requirements.


Supervisors are often the last defense against drug and alcohol abuse on the job. Because supervisors are both in a position of authority, and in a situation where they often work in close proximity or communication with employees, they’re uniquely suited for catching abuse and addiction problems. However, supervisors must complete reasonable suspicion training before they can make any recommendations for treatment, counseling, therapy or even testing for drugs or alcohol. Reasonable suspicion training takes a total of 120 minutes, divided into 60-minute segments. One segment is dedicated to covering drug use, and the other to alcohol. Both focus on signs and symptoms present in employees under the influence, but they also focus on helping supervisors enforce company policies and even helping employees find the help they require.

Other Employees

Supervisors are not the only employees who must go through DOT drug and alcohol training. General employees must complete a minimum of 60 minutes of training as well. This program differs significantly from reasonable suspicion training. It covers topics ranging from the health effects of drug and alcohol abuse to where and how employees can get assistance and counseling if they need it. While the DOT mandates a 60-minute course, the organization actually recommends 120 minutes of training.

Where to Find Training

For DOT companies, the most important consideration is finding a reputable training provider to ensure compliance with federal mandates. DOT drug and alcohol training isn’t something that can be left to chance. While the Department of Transportation does allow companies to choose the method of training delivery, this can be problematic. After all, your company specializes in transportation, not education. Finding the right DOT drug and alcohol training company will offer significant savings in terms of both time and money while ensuring that both supervisors and general employees receive the high-quality training necessary to safeguard passengers and create a safer environment.

Choose your training provider with care, though. Check the company’s history, course offerings, and training delivery formats to ensure they mesh with your needs.
