In order to drive a bus for 13 hours, how many hours off duty must you have had prior to this period?

To drive a bus for a duration of 13 hours, regulations typically require that a driver must have had at least 8 hours of off-duty time prior to starting their driving period. This off-duty time is essential for ensuring that the driver is well-rested and alert, which is crucial for safety on the road.

Having a minimum of 8 hours off duty allows drivers to recover from fatigue, reducing the risk of accidents caused by drowsiness. Regulations in the transportation industry are designed to promote safe driving practices and minimize the potential for operational errors caused by driver fatigue.

Other options suggest less time off, which does not align with safety protocols aimed at maintaining high standards for driver well-being and alertness. Each choice represents a different approach to off-duty requirements, but only the correct answer adheres to the regulated standard.
