When must a property-carrying driver take the required 30-minute break?
a.After 4 hours on duty
b.After 10 hours on duty
c.Every 2 hours of driving
d.Before driving more than 8 cumulative hours without at least a 30-minute interruption of driving time
解析
The rule triggers on 8 cumulative hours of driving time and can be satisfied by any 30 consecutive minutes not spent driving. It is not tied to 4 or 10 hours on duty, and there is no requirement to break every 2 hours.
