Is this related to the mexican trucker thread? I see about a dozen of them get out of a car at walmart. Not sure how many can fit in a tractor!
actually, i'm thinking more like, if there are two seats, the driver's seat, and the passenger seat.............that's the total amount.......2.........
I once rode around with a guy in his sleeper for orientation, his 2nd seat had been removed so he could use his fridge on top of the HVAC unit, this was in an International 9400. My guess is there may be a reg but its more likely to be a thing where you need permission for a rider in a company truck, and the permission for more than one rider would be hard to get. AJ
I know the government runs an operation that has three drivers up in the cab. They drive in 8 hour shifts. But I would go and say that the number of people you can have in the truck cab is limited to the restraint belts or seat belts. Two in the front for each seat and one in the bunk.
