This is something that I have been very curious about. We have stopped to help other tow trucks, and especially recently had a few stop to block the lane for our guys. This has raised a question for me about the liability and all if something goes wrong. What if our truck is hit out there blocking for someone else?? So far, we have figured that I would worry about that when and if it happens, as our intent is to do the right thing and help to keep another operator safe. But you know we will be in the law suit over it. Doing the right thing sure could turn into a nightmare in a hurry. We are looking more and more into putting a specific traffic control unit into place, but that comes along with a while new set of problems.
