What is the maximum number of hours a driver can work before needing to rest?

Answer: C — 15 hours

The maximum number of hours a driver can work before needing to rest is set at 15 hours. This regulation is in place to ensure safety on the road by mitigating the risk of fatigue, which can impair a driver's ability to operate a vehicle safely. A driver is typically allowed to work up to 15 hours within a 24-hour period, but it's important to note that this is usually inclusive of driving time and any other work-related activities. After reaching this limit, the driver is required to take a rest period, which helps maintain attention and responsiveness while driving. This regulation is especially critical in commercial driving situations where long hours can lead to increased accident rates due to drowsiness. Understanding these limits is essential for ensuring both personal safety and compliance with regulatory standards in the transportation industry.
