1. General Hours of Service Guidelines
- Drivers may drive up to 11 hours, but are limited to 14 hours in a duty period
- The 14-hour duty period may not be extended with off-duty time for meal and fuel stops, etc.
- Each duty period must begin with at least 10 hours off-duty
- Drivers may work 60 hours on-duty in seven consecutive days; however, drivers can restart the 7-day period by taking at least 34 consecutive hour's off-duty
- Beginning July 1, 2013, a driver must take a 30 minute rest break following 8 hours of driving time.
- Beginning February 27, 2012, on-duty time does not include any time resting in a parked vehicle (also applies to passenger-carrying drivers). In a moving property-carrying CMV, does not include up to 2 hours in passenger seat immediately before or after 8 consecutive hours in sleeper-berth.
This is the interpretation from the DOT provided to UPS and approved by the DOT for package car drivers since the early 80's (I remember a clarification memo from the DOT back in 1984) and probably before.
I have not heard of any changes to the original interpretation approved by the DOT but it is a government agency, so caveat emptor.
Of course, the 2012 and 2013 are new.
