If he has a trolley brake and applies it, it will do nothing,(except drop air pressure from the sec.) If this was an older truck that someone stretched I could see it, but there should not be a TB on a straight truck that isn't setup to pull a trailer.

Am I way off base here???

All the air braked straight trucks I have been in have had a trolley brake. I think they are setup like that for running a pintle trailer with air brakes. Then again most of the "straight" trucks I have been in were construction trucks or tandem dumps.

OK, makes sense, I guess I was thinking box truck, like expedited freight.

I use it when someone is tailgating me lol

It's the company brakes lever.
