Idle , you guys mean leave the truck running? I drive Concrete Mixer Trucks and sometimes we'll wait for loads for an hour or two and have our trucks running(idling the whole time) I don't know if that's what u mean by idling, but anyway i can't believe they don't mine having our trucks idling for so long, b/c its such a waste of fuel, but if they don't care then i don't care. Im getting paid for waiting so Im not bad just bored. If i was doing long haul i wouldn't even be getting paid unless the truck was moving.
