Ok, I'm reading this whole thing trying to get a handle on the kind of runs we'll be able to book our solo trucks on once this goes into effect. Before you had 11 hours to deal with and now you have 10. So for a load that has to run straight through, that's pretty easy to figure out; you lose about 60 miles or so on the loads you can book. But where it gets tricky is for loads that might have about 24 hours to complete or for longer loads that would run over multiple shifts when you have to figure out the transit time.
Before I would figure out 11 hours on and 10 off, or basically 21 hours for each chunk of miles the truck could do in 11. Now you have the guy only able to driver for 10, but he's able to get back at it 2 hours faster, so you could in effect be gaining an hour per 21 hour period on the longer loads, which could mean a solo can do a longer load faster than before. So now a solo has a slightly better chance of being able to get a 1000 mile load or longer, but those 700 milers out out of the question now.
