Fueling Your Tractors

I was told by an experienced driver that it's common for professional drivers to use bungie cords while fueling. Is there any truth to that? He mentioned fueling is a perfect time to clean your head lamps or windows. But i mean federally it's illegal to stay away from your tank while you're actively fueling your vehicle. Right? I believe it would make an amazing tool to multi task and stay safe. While you do an unsafe thing lol. I guess I'm just confused. Do drivers/officials just feel comfortable enough to do this, or am i really just thinking to much about it?

I know for hazmat it states: 397.15: Fueling.

When a motor vehicle which contains hazardous materials is being fueled— (a) Its engine must not be operating; and (b) A person must be in control of the fueling process at the point where the fuel tank is filled.

Thats why nozzles have locking levers on them. I lock it open and wash my windshield. The tanks are close enough, what 3-4 ft away at most.

I found, very specifically lol. Flying j's and cascadia trucks passenger fuel tank don't quite get along. I use a bungee to keep it in while i walk around the truck to do my Windows while it fills. Otherwise, I'd end up with a huge puddle of fuel on the ground. Bad habit of slipping out. Might just be a good idea to wrap one around the handle just in case...
