  DOT Reasonable Suspicion Testing training teaches managers and supervisors how to identify signs of drug and alcohol use in employees who hold safety-sensitive positions under DOT/FMCSA regulations, and how to properly refer employees for reasonable suspicion drug and alcohol testing. The DOT requires at least 2 hours of training, which is split between this Part I course and the separate Part II course.

  Under 49 CFR Part 382, motor carriers must ensure that all persons designated to supervise drivers receive at least 60 minutes of training on alcohol misuse and at least 60 minutes of training on controlled substances use. This training is required for any manager or supervisor who may need to determine whether a driver or other safety-sensitive employee should be sent for reasonable suspicion testing.

Part I takes approximately 45 to 60 minutes to complete. It is fully self-paced, so you can pause and resume at your convenience. You have 6 months from enrollment to finish. Progress saves automatically on the same device.

  Part I covers DOT/FMCSA drug and alcohol regulations, an overview of reasonable suspicion testing, what makes suspicion reasonable, general signs of substance use disorders, behavioral signs of drug use, and the responsibilities of managers and supervisors in initiating the testing process.

   Yes. The DOT requires a minimum of 2 hours of reasonable suspicion training for supervisors, with at least 60 minutes on controlled substances (Part I) and at least 60 minutes on alcohol misuse (Part II). Both parts must be completed to meet the full DOT training requirement.

  No. This course provides a printable certificate of completion. It does not include a DOL or OSHA card. This training satisfies DOT/FMCSA requirements, not OSHA Outreach requirements.

  The DOT does not specify a mandatory renewal interval for reasonable suspicion training. However, many motor carriers require refresher training every 1 to 3 years as a best practice, and some state regulations may require more frequent training. Check your company policy and applicable state requirements.
