What is the maximum number of driving hours permitted for commercial drivers in one day?

The correct answer corresponds to the regulation that allows commercial drivers to operate a vehicle for a maximum of 11 hours after taking a minimum of 10 consecutive hours off duty. This rule is part of the Federal Motor Carrier Safety Administration (FMCSA) hours-of-service regulations, which are designed to ensure that drivers get adequate rest and operate vehicles safely.

By allowing 11 hours of driving after a 10-hour rest period, the regulation recognizes the need for sufficient downtime to prevent fatigue while also enabling drivers to cover a significant distance during their workday. This balance is crucial for safety on the roads, as fatigue can impair a driver's ability to drive effectively.

The other options present incorrect driving limits or incorrect rest requirements. For instance, limits such as 10 or 12 hours do not comply with the current regulations set forth by FMCSA, which clearly states that the limit is 11 hours of driving after 10 hours off duty. This makes the answer not only compliant with the regulation but also a reflection of the balance between work and rest that is critical in the commercial driving industry.
