we impound tractor trailers by subcontracting tow trucks from abc towing in clearwater. generally i break into the tractor so we can easily run air to the tanks, to release the air brakes...and to put the tractor in neutral if its in gear...

there are a few other misc things that sometimes need to be done...but for the most part its really not that difficult.

its pretty lucrative when i can find a tractor/trailer. both are class d vehicles and that allows me to charge 400 per unit.
