A couple of weeks ago I had a Pottery Barn order for a residence. I'm pretty sure it was either a couch or an easy chair---in any case, it was way oversized as well as being over 70 lbs. Its girth was such that getting a handtruck under it was pretty well impossible. So I chose to back into the customers driveway in order to get as close as possible to the garage. I followed all proper methods; I honked, I cleared the area, I approached the delivery so as to make a driver-side back, I backed at a safe, controlled speed, and I backed only as far as necessary to avoid blocking both lanes of the street. I had backed into this driveway once before without incident for a similar delivery, but on this occasion the weight of my remaining deliveries plus the condition of my back tires (almost bald) caused the bottom of my trailer hitch to grind on the customers aggregate driveway and leave a nasty scrape mark. I have been told that I will be charged with an avoidable backing accident and issued a warning letter, even though I have routinely scraped the bottom of my bumper on the steep driveways in my rural area for the last 16 years and never once been charged. The explanation for this discrepancy is that "I was backing up when it occurred instead of going forward." I feel bad about damaging the driveway, and I realize that UPS's insurance company will have to pay for the damage, but the fact is that I followed all relevant methods and it isnt my fault that UPS chose to "go cheap" and install a low-hanging aftermarket hitch on my car instead of fabricating one that mounts above the bumper as has been done on the older cars I have driven. Its a design flaw that is entirely fixable if the company were simply willing to spend the money to do so. I could care less about whether or not I am "charged" with an accident, or whether or not I have to wait an extra year to get my 14-year safe driving award. But the warning letter is a threat to my job, and I think its BS. Opinions?
