The new rules of service as summarized in the Business Journal are:
drivers may not drive more than 11 hours following 10 hours off duty, beyond the 14th hour after coming on duty after 10 hours off duty and after 60 hours in seven days or 70 hours in eight days. A driver may restart a driving period after taking 34 consecutive hours off.Actually, that is a bit of oversimplification, as there are a fair number of exceptions, check out the FMCSA's page or a summary at the Trucker's Report for more details, but it does give you a feel as to the juggling issues transportation companies are now dealing with.
