You will not run ilegal with Fedex CC unless you are deadheading somewhere. They are very strict about the HOS rules and you will simply be not offered a trip that requires a team. If no teams are available they will ask you to haul the freight to a transfer location and then bring in another truck for the remainder of the trip.Depending on where you live you can make a modest living driving solo but plan on being away from home a lot.We are a team and after much analysis we believe the 2nd driver is responsibile for 60 % of the income.The computer tracks your hours of on duty plus driving time, so in many instances you may have taken a 5 hour trip and only have 5 hours left,so if a run comes up that the computer schedules at 5 hours and 1 minute you will be passed over and never know about it..another disadvantage of being solo is that you could get stuck on a nighttime schedule.Many trips load at night for 0500-0700 deliveries,then you are out of hours untill the next night..
