Guidance Q&A

Question 25: When a driver experiences a delay on an impassable highway, should the time he/she is delayed be entered on the record of duty status as driving time or on-duty (not driving)?

Guidance: Delays on impassable highways must be recorded as driving time because §395.2 defines “driving time” as all time spent at the driving controls of a commercial motor vehicle in operation.
