UPS doesn't care if you're "seasoned" or not.
You will find, if you haven't already, they want you to do things, "The UPS Way", which may seem bass-akwards to you but do it anyway to pass.
On funny local example I know of first hand. A friend of mine, now retired, came out of package car. Had to do the whole school thing. Supe took him to DMV for the whole smear. Passed written. Went out for pre-trip, started to heel-kick tires. Examiner said, "You might as well stop right there. You're done". Our supe said, "Why?". Exam said, "You must thump tires with solid object such as hammer". Supe, in his usual arrogant "UPS Way" said, "No, THIS is they way we teach our new drivers". Examiner then said, "Well, it's WRONG and he flunked. Try again."
Another: "The UPS Way" is to pull out in intersection without shifting. Supe was with me one day for annual. He drove for his mandatory hour. Pulled out of truck stop on green light that turned red while he was starting thru. You think he'd fire it up and shift like he'd never shifted before to get outta the way? Nope. 1st gear (which I NEVER used) all thru the intersection. I thought we were gonna get T-boned. The scariest ride I'd ever had.
So, do what you hafta do. Don't argue and say, "Well, THIS is how I learned". Just do it, pass and when you're on your own, just safely drive as you think best. It worked for me for 32 years.
