70 hours over 8 days is 8.75 hours per day. I talk to truckers on a weekly basis that say they are hamstrung by regulations. Some days you feel like driving and some days you don't. With the current regulations, you may have to pull over at a rest stop when you are 30 minutes from unloading or 30 minutes from home. Peace.
There is way to complete the trip by using the “Personal Conveyance” option. However, if a driver is caught violating rules concerning personal conveyance, it will likely result in a fine and loss of that option.
