Final answer:
Based on typical U.S. regulations for commercial drivers, after spending 2 hours on non-driving duties, a bus driver might have a remaining 12 hours of working time, which includes driving. This presumes a 14-hour total limit on working hours. The options provided do not match this scenario exactly, making the answer indeterminable without more context.
Step-by-step explanation:
The question relates to regulations impacting a bus driver's working hours, a topic typically covered by transportation or business coursework. In the United States, the Federal Motor Carrier Safety Administration (FMCSA) regulates the hours of service for commercial drivers. According to these regulations, a bus driver may drive a maximum of 10 hours after 8 consecutive hours off duty. However, the question seems to imply there may be a different set of rules that apply, where inspection and cleaning time may count against the total allowed working hours. Without a direct reference to specific FMCSA rules or assuming the scenario implies a 14-hour working window (which includes all working time), if the driver has already spent 2 hours on non-driving duties, they could potentially have up to 12 hours remaining for all work, including driving. Hence, they would be allowed to drive for the remainder of that time, assuming they do not engage in other non-driving duties. As there is no exact answer provided in the options and based on the typical 14-hour rule, it might be closest to option b.14, but this is an educated guess given the lack of context in the question.
