CAR follows all state and federal laws. By law, you must take a full, uninterrupted 6-hour break for every 14 hours you're in driver mode. These 14 hours in driver mode do not have to be consecutive. Once you have been in driver mode for 14 hours, certain regions have local regulations that determine how long a driver can stay in driver mode and how long their break must be. See requirements in your area by selecting your city or state here. State Requirements
