When two people are driving on a road trip, what is the maximum time they should share driving in a day?

The guideline for sharing driving time during a road trip is based on safety and fatigue management. Sharing the driving responsibility helps ensure that neither driver becomes too tired, which can impair judgment and reaction times. The typical recommendation is that the total driving time in a day should be kept to around 11 hours when two people are sharing the driving.

This amount allows for adequate rest breaks, meals, and time to recover between shifts. Driving for longer than this can increase the risk of fatigue for both drivers, as the hours spent on the road accumulate and concentration may wane. By adhering to approximately 11 hours of driving, each person can ideally get sufficient rest, thus maintaining alertness throughout the trip. It emphasizes the importance of planning and recognizing the limits of safe driving practices over extended periods.
