Interesting.

When the Sup's came out I emailed DC Region & asked what they were after, where to get them and WHY we needed them (I bitched a bit about it). The response I got was that they were not going to be required provided the car had white on black or black on white lettering.

All the stuff I'd seen posted was that they were moderately expensive and rather fragile so if they took a hit or a rock they were shot.

So are they required or not?
