Final answer:
The maximum on-duty hours for bus drivers in a seven-day period typically depend on regulations and company policies, with examples like 70 hours in 8 days for property-carrying drivers and 60 hours for passenger-carrying drivers in the United States under FMCSA rules.
Step-by-step explanation:
The question asks about the maximum number of on-duty hours a bus driver can undertake in a seven consecutive day cycle. The correct answer to this question isn't provided directly in the information given, as it might pertain to specific regulations or company policies which can vary based on location and governing transportation bodies.
For example, under United States federal regulations by the Federal Motor Carrier Safety Administration (FMCSA), property-carrying drivers may drive a maximum of 70 hours on duty in an 8-day period before they are required to take a 34-hour reset. However, for passenger-carrying drivers, this maximum is often 60 hours on duty in a 7-day period before needing a reset. Actual hours can be subject to agreements, company policies, or different countries' regulations.
