I at one time ago drove a semi truck and trailer and I did not like peeing in bottles but if you are waiting to deliver a load at a customer and their is houses all around you you don’t need a exposing yourself in public court case. Now I talked to a dump truck driver with a broken arm. He said don’t drive with a bottle of pee in the truck. He wrecked his company’s dump truck and broke his arm. The  e.m.t washed him off with bottles of water as he was standing on the side if the road in his underwear because his truck rolled and a pee jug broke inside the cab. The bad thing or funny your pick was it was not his bottle. Now I have hauled fedex loads and my other have has load Amazon load and you stop they make calls to you or your company to ask why. Now with fed ex I would pick up the load from one driver in Iowa city and drive it straight to Indianapolis with out stopping to make fed ex happy. So do drivers use bottles to pee in yes but local should never have to but they do because I don’t think you or everyone would let a delivery person use your bathroom i know I would because I was a driver. A I laugh at the catheter part because I tell my other half to get a catheter and hang the end out the window all the time.
