Questions
Frequently asked questions
Is this training required by DOT?
Yes. Under 49 CFR 382.603, anyone an FMCSA regulated employer designates to supervise CDL drivers must complete at least 60 minutes of training on alcohol misuse and 60 minutes on controlled substances use. That must happen before they make a reasonable-suspicion determination. This course covers both 60-minute requirements.
Who should take it?
Anyone who supervises CDL drivers and may have to decide whether to send a driver for a reasonable suspicion test. That includes owners, safety managers, fleet managers, dispatchers and DERs. If you are an owner-operator with no other drivers, take Owner-Operator DOT Compliance Training instead.
Is there a follow-on course?
Yes. This course teaches you to recognize the signs of alcohol misuse and drug use. Our Reasonable Suspicion Interview Skills course teaches how to handle the conversation with the driver. Many supervisors take both.
Can we train our whole team?
Yes. Team pricing is available for fleets and companies training several people. Call 980-655-4455. goMDnow Consortium members also save 30% on every course when they sign in.
Does the certificate expire?
No. Federal rules set no refresher interval for this course. Your certificate carries a unique verification ID that an employer or auditor can check on goMDnow's verification page, so keep a copy on file. Retake the course when the regulations change or when someone new takes over the role.
