There are also the ones that will open the flapper when breaking up a set, pull out from the rear, hit the brakes and then quickly gun it. The dolly will pop up as it is coming out from the rear box, pop off the pintle and then fall to the ground.
Bam. Dolly off the lead all in one move, without having to get out and remove the dolly.
But, I had a driver ride back with me after being discharged because this time he did it, the dolly popped off alright, but then raised up too high in the front and it knocked out the bottom door panel. The guy did this move all the time, but this time, I guess he did not gun it fast enough as the dolly was popping off the pintle.
Don't know if was being lazy, or just showing off, but it ended up costing him thousands of dollars in the end.
