What is the 11-hour driving limit?

The 11-hour driving limit is a cornerstone of the Hours of Service (HOS) regulations established by the FMCSA.

• A driver may not drive for more than 11 total hours during a single duty period.

• These 11 hours must fall within a 14-hour on-duty window (which includes driving and non-driving activities).

Key details:

• Drivers must take at least 10 consecutive hours off-duty before starting a new duty period to reset their driving hours.

• If the 11-hour limit is exceeded, the driver is in violation and may face penalties, including out-of-service orders.

This rule is designed to prevent fatigue-related accidents and ensure drivers remain alert while operating a vehicle.
