What does the "12-hour rule" for commercial drivers entail?

The "12-hour rule" for commercial drivers is established by federal regulations to ensure safety on the road by providing limits on driving hours. It specifies that drivers of commercial motor vehicles are allowed to operate their vehicles for a maximum of 12 consecutive hours after they have been off duty for at least 10 consecutive hours. This regulation is intended to prevent driver fatigue by ensuring that operators have sufficient rest before they begin their driving period.

The 12 hours of driving must be part of a larger context of regulations that focus on overall work hours and rest breaks, supporting the safety of both the drivers and the public. By limiting the hours of operation following a required rest period, the rule helps mitigate the risks associated with long hours of continuous driving, which can lead to decreased alertness and increased chances of accidents.

While other choices suggest variations on driving and rest time, they do not align with the established regulations that emphasize the combination of a specific off-duty requirement followed by the maximum driving time.
