To thrive as an instructor or coordinator for a CDL Refresher Course, you need in-depth knowledge of commercial driving regulations, safe vehicle operation, and a current or previous CDL license. Familiarity with simulators, electronic logging devices (ELDs), and current Department of Transportation (DOT) compliance systems is essential. Strong communication, patience, and teaching skills help you effectively support returning drivers with varied experience levels. These skills ensure trainees regain confidence, remain compliant with industry standards, and maintain high safety standards on the road.
