They really don't cover the "designated walkpath" idea. I mean, when you do their yard training lot, you pull up to make your delivery and the supervisor would instruct you how to do it. Pull close to the curb if house was on the right side of truck....pull past house if its on the other side of the street so that you can walk behind and check for traffic, but that's about it. The more "fun" one is the slippery surface station where you walk first with your normal boots, then put on hospital style booties over your shoes and walk and slide all over the place.
Now, I went over 2 years ago, so things might have changed or been improved.......Oh, wait this is UPS....nothing will have been improved
