Gee, I am not a "real truck driver", but even I know that you should scan the area you are backing in to before starting the back.
I was involved in a hit while parked a month or so ago. I was legally parked making a delivery at our local college. A tractor trailer was trying to back on to the loading dock next to where I was parked and misjudged the clearance, hitting the left side of my hood. There was a metal railing between me and the dock ramp and had he not hit me he most surely would have hit the railing.
I was not charged with an accident yet still had to do all 3 parts of the Tier 1 Safety Assessment----easiest 20 minutes of pay I ever made.
Okay, my response is not to start a conflict with you but just to point something out that you might not be aware of .
Let's assume this driver wanted to back into bay 153 , bay 152 had a tractor hooked up to a trailer. Driver came past bay 151 , bay 152, and then scanned bay 153 and surrounding area. okay, bay 153 is empty, tractor there on 152 , I need to be careful, he thought. Once he started backing it in, he loses sight of the right (passenger)side of the trailer as the front of the trailer is blocking his line of sight. That side is where that tractor is. Can't see what's going on there and due to his inexperience and wishful thinking, he hoped for the best or assumed the best was happening as he tried to get it in.
Now Ups doesn't emphasize G.O.A.L.,
Get
Out
And
Look but he should have done that. Or pulled up, if space allowed so he could straighten up a bit and be able to use that right , passenger side mirror as he tried to back in again.
Backing up is the most difficult thing to do when it comes to tractor trailer driving, in my opinion. 53 foot trailers track differently than 36 foot pups. You're simply not driving the same vehicle all the time as you do with a package car. Parameters change all day as you change combinations.
He's not the first guy to back into a tractor. If the tractor were an old international with a week to go before going to the junk pile, that's a better scenario than backing into a new tractor, in management's eyes.. The first case is easier to overlook than the second. But I don't even know if this applies, so enough speculation about that.
Where I can speculate with more confidence is this: it is now casual peak driver hiring time. Seasonal drivers are seasonal but there are also way more seasoned than guys who just came in from package into feeders, and also generally cheaper and more easily pushed around.
By not overlooking this on property accident, management just got rid of a top rate rookie feeder driver and replaced him with an experienced low rate driver.
