I do this all the time. I’ve put it on a bay in an RDC, reached the drivers’ room, then turned around and gone back to check the handbrake. And it’s always on. My most common one though is getting halfway down the road and thinking “is my dog clip on?”, then looking for somewhere to stop so I can check. It’s always been on.
And though I double check that I’ve wound the legs down and pulled the suzies off, for some reason whenever I pull out from under a trailer I always wait for the ‘rip…BANG… WHOOOOOOOOOOOSSSSSHHHH’ of a suzie smacking the back of my cab as it springs back.
