What is the maximum time a driver can operate a commercial vehicle without rest?

The maximum time a driver can operate a commercial vehicle without rest is 11 hours after taking a minimum of 10 consecutive hours off duty. This regulation is part of the Hours of Service (HOS) rules established by the Federal Motor Carrier Safety Administration (FMCSA) in the U.S. The purpose of these rules is to ensure that drivers are well-rested and not fatigued, which helps to improve safety on the roads.

Operating for 11 hours allows drivers to complete longer trips in one go, which can be beneficial for meeting delivery schedules while still prioritizing rest. It also ensures that they adhere to the requirement of having sufficient off-duty time before resuming driving activities, which is essential for reducing the risk of accidents due to driver fatigue.
