DOT reasonable suspicion training prepares supervisors of CDL drivers to recognize physical, behavioral, speech, and performance indicators that may justify a drug or alcohol test under FMCSA rules. Regulation 49 CFR 382.603 requires supervisors who may make these determinations to receive at least 60 minutes on alcohol misuse and 60 minutes on controlled-substance use. This online course covers observable signs, documentation, post-determination procedures, and compliance scenarios so employers can act consistently and defensibly. After completing the course and passing the assessment, the learner receives an instant certificate for audit and compliance records.

Source-backed compliance answer
Under 49 CFR 382.603, each employer must ensure that every person designated to supervise CDL drivers receives at least 60 minutes of training on alcohol misuse and at least 60 additional minutes on controlled-substance use. The training is used to decide whether reasonable suspicion exists to require a driver to undergo testing under DOT/FMCSA rules.
CDL Schools USA's DOT Reasonable Suspicion Training is built as a 2-hour online supervisor course for fleet managers, dispatchers, safety directors, DERs, terminal managers, and trucking-company owners who need a documented training record before a DOT audit, driver incident, or new-supervisor onboarding deadline.
The training is for anyone the employer may rely on to make a reasonable-suspicion call for a CDL driver. That commonly includes supervisors, fleet managers, dispatchers, safety managers, DERs, and owner-operators who manage other drivers.
The certificate gives the employer a dated training record showing that the learner completed the alcohol and controlled-substance awareness topics required for supervisor reasonable-suspicion determinations. Keep it with audit and driver qualification records.
Reasonable-suspicion decisions are time-sensitive. Training before an incident helps the supervisor observe physical, behavioral, speech, and performance indicators, document facts clearly, and follow testing procedures without improvising under pressure.
