Trailer bumper

I was just curious if the trailer contains a separate bumper zone. I know it has a bumper perimeter, but the existence of a separate zone would be important when considering what types of contact are legal.

The trailers (all six of them) use standard bumpers as defined in <R08>. Said standard bumpers must by definition be in the bumper zone, which pretty much covers the entire field in the volume between 1" and 7" off the floor.
