What is the maximum allowable hours of driving for a commercial driver in a day?

The maximum allowable hours of driving for a commercial driver in a day is indeed 11 hours of driving after completing 10 consecutive hours off-duty. This regulation is part of the Federal Motor Carrier Safety Administration (FMCSA) Hours of Service (HOS) rules, which govern how long a driver can operate a commercial motor vehicle to ensure safety on the road.

Under these regulations, after a driver has had at least 10 consecutive hours off-duty, they are permitted to drive up to 11 hours within a 14-hour window, after which they must take another off-duty period to rest. This structure is intended to prevent driver fatigue and promote safe driving practices.

Other options presented do not align with the established federal regulations. For instance, 10 hours of driving after 8 hours off-duty does not meet the requirement, and the same applies to other combinations that do not adhere to the 10 hours off-duty or exceed the driving limits permitted. This standardized driving time is critical for maintaining safety standards in the trucking industry.
