How many hours in 8 consecutive days may a driver legally drive?

The legal driving limit for a commercial driver within an 8-day period is 70 hours. This rule is specified in the Federal Motor Carrier Safety Administration (FMCSA) regulations, which govern the number of hours a driver can work to ensure safety on the roads.

Under these regulations, drivers are allowed to drive a maximum of 11 hours after coming off a 10-hour off-duty period, but the total working hours cannot exceed 70 hours in an 8-day workweek, or 60 hours if they work for 7 consecutive days. This limit is in place to prevent fatigue and promote safe driving practices.

Knowing this, it becomes clear why the option indicating 70 hours is the correct choice. If a driver reaches this limit, they must take a break period off-duty that allows them to reset their driving hours; this is necessary to maintain compliance with the regulations and ensure safety on the roads.
