I too carry a class A CDL, but the hoops for pulling doubles or Hazmat are a pain for sure! This week I had a “city driver” refuse to cross bridge onto property, he thought he could not do it without going into ditch! I offered to pull the load across for him and also explained how to set up the approach but he was having none of it. As a result I unloaded 9 pallets of tiles aprox 20 K pounds out in the street. arghh! Keep in mind I typically had a crane attached to my truck! I was good up to 100k pounds. Anything over that and I had to recertify.
