I hear ya Von. ...and UPS sees it also as heightened driver awareness when we must use the horn and ensure the backing maneuver is performed safely.
However, if common sense overflowed the minds of everyone, then accidents wouldn't likely happen.
Hard to see what's going on behind a 53' trailer, let alone hear the tractor. Not saying this incident involved a 53' but back up alarms should be mandatory.
I thought they were required in most states?
If common sense overflowed there'd be a lot less people on this planet. Back to topic.
From my understanding the accident was a person pinned between a tractor and the front of a trailer.
Dont you have to get out of the jockey can first and make sure theres no one around?
No, Nut, one does not get out and look around every time when backing. Only if you feel the situation may have changed.
To try and answer both your questions,
Imo I don't feel it's any more difficult/dangerous to back up a 53' than it is to back up a 28'. If your are pulling or backing a trailer in a straight line the amount of blind area directly behind you is the same, roughly 8.5' wide x13' high. What differs based on trailer length is how far behind you that blind area extends.
To me though it's all incidental if you follow the proper procedures for spotting a trailer.
Scan the area as you approach it.
Scan the area and the bay as your arrive.
Scan the area as you set up.
Begin your back.
If you do that you'll have both a mental and visual picture of your area and what's in it.
As far as safety items being mandatory on vehicles I'll make a long story short. My fathers equipment repair company has a maintenance contract with the state of MN to repair/maintain state vehicles. These have all the latest safety pieces on them. The number two reason that equipment comes into our shop is for damage repair from people crashing into them. People not paying attention,etc, are going to continue to do so irregardless of what safety requirements are around them.
What's the saying, You can't fix stupid.
