Another way, see something that might be unsafe or call for out of service, write it up. Make sure a copy is left in the truck if possible. Tires under 4/32nd steel cord showing, especially convertors, brake chambers leaking, or anything you can find. That will send a message to any TM. And how can they fight you pointing out safety issues. You might not be allowed to deadline equipment, but you sure can write it up. Keep or make an extra copy & pass it on to the next shift. Keep a list in the yard horse or the next jockey. It might be helpful to everyone. Especially the road drivers. No one wants to drive bad equipment. If the freight is on a tight schedule, find & fix the problem before the road driver does & sits for the next 2 hours. If memory serves me, it is more costly to repair once on the road than in the yard. I imagine a through pre trip inspection might find something wrong that needed repair before hitting the street. von.
