Questions about long hauling???

I am thinking about doing the car hauling but i have some questions i was hoping someone could help me out with.
(I have asked these questions and i have gotten different answers)
(and my next step was to go talk to the CHP and ask them in person)

1.Do I need a another license besides the regular class c I already have?
for example if im goin to have a dually wit a trailier that totals roughly 70 feet and that can carry 3-4 cars, do i need another license?
(i have been told yeah and no, so hopefully someone can help me wit this, and then ill post my other questions)
thanx in advance

 

ok but #### i asked someone that was hauling 3 cars (suv, bmw, and and a extended titan) and he said no.
so is it required?
cuz these dont go over the scales as far as i know
thanx for the help

 

yeah its not that i dont believe you
im tryna get more info (thats what this place is for i thought)
i thought maybe i was missin something, cuz more drivers (who haul) told me i didnt need a license other than a class c

 

but its not a big rig
i dont know how to post pics but its jus a trailier with a dodge pick up
#### its crazy cuz im gettin all this different info
thanx for your help

 

i dont know if it will have those types of brakes, but im guessin no.
but yeah im goin to go to the chp and ask them but i thought maybe before i go theres a certain term i need to tell them otherwise they might get the wrong idea of my questions
thanx for your help jsmitty
i have more questions but ima wait to ask them, until i figure this out
