I would argue it's 11 hours from on-road to off-road, MINUS breaks, as long as you stay under 14. I've pulled the plug at 10.75 hours to make it back and off the road by 11. I don't need some state cop with a superiority complex looking at my simple time card and asking "oh, but how long were you stopped?" Unless you pull telematics.... you couldn't prove to the cop the time you weren't driving... so I'll take it safe and stop at 10.76h of "on road" time, because I haven't heard from my employer (who would have something to gain) to state that "11 hours of driving but you get one minute credit for every delivery, so if you had 120 stops, you could drive for 13 hours but not on the clock for no more than 14.
