"provided towed vehicle is more than 10,000 LBS."
Actually not completely correct!
If you're combo unit (truck and trailer) grosses over 26000#, even if your trailer only weights 3000#, you're still a combo unit, which requires you to have a minimum of a Class A CDL restricted license. The "restricted" means you dont have airbrake endorsement. Which you only need - if you have airbrakes!
26000# and a trailer of any size is the breaking point. There is no "if this or if that"
But if you're grossing under 26,000# and if you're pullin a trailer that is factory rated at or OVER 10,000# .....you need a class A CDL!
Any vehicles grossing 10,000# or more - you must have a DOT Medical card. This goes for pick up trucks as well. A pick up weighs at least 7000#. A trailer weighs NO less than 2000#, 1 walk behind is 600#? Add up the weight of gas cans, line trimmers, blowers, passangers, and you're over 10,000#!
