Our company policy is to pray that someone sees you. I've only been stuck once and I had to have some random lady jump in the truck and start it for me. Pretty ridiculous since I work for a company that has a bigger safety manual than the IRS tax code. I forget my phone every now and then which leaves just praying that someone is in ear shot. I carry a rope, but I feel more comfortable waiting then trying to lower myself. There's no backup if the truck shuts off for us.
I've thought about this before. Maybe I will bring it up again, but I've been told to stop calling our safety department and embarrassing them.
