After taking 10 consecutive hours off duty, a driver begins to work at 8:00 a.m. The driver may operate a commercial motor vehicle until what time?

The 14 Hour On Duty Limit This limit is usually thought of as a "daily" limit, even though it is not based on a 24 hour period. You are allowed a period of 14 consecutive hours of on duty time after being off duty for 10 or more consecutive hours. The 14 consecutive hour duty period begins when you start any kind of reportable work (performing vehicle maintenance, loading / unloading cargo, fueling, driving, etc.). Once you have reached the end of this 14 consecutive hour period, you cannot drive again until you have been off duty for another 10 consecutive hours. Your driving is limited to the 14 consecutive hour on duty period even if you take some off duty time, such as a lunch break or a nap, during those 14 hours.
