Charlee, that's funny.
My late husband was backing across a street - broad daylight. Thank goodness his trailer was high and he had a bunch of wooden pallets loaded underneath the trailer. A guy in a pickup truck was coming down the road and ran underneath the trailer. The only thing that kept his head on his body (literally) was the fact that the pallets stopped the pickup from going completely underneath the trailer.
Fortunately, he got the ticket - and caught H because his MIL had just bought him the truck to go to work - seems he had had a few and wasn't paying attention. Like, how can you not see a 40 foot trailer?
