What this lesson covers
This lesson covers the federal limits on how long a commercial driver may drive and be on duty, and the alcohol and drug rules that decide whether a driver may perform safety-sensitive work. These limits and thresholds are common exam questions and the first things to check when a driver is tired, late, or suspected of impairment.
