Question
how far must car be on truck before there is a charge?

Answer
Depends on the laws of the city or state.  Some places all the tow truck has to do is be there and there will be a charge... Some cases they just have to be touching it.

Others they have to be all the way hooked up but not moving. Some they have to be hooked and moving...
