I'm pretty sure this is very illegal, especially with a big company like UPS. Anyways, I made a stop at a local Rite Aid store today and seen a UPS truck sitting by the entrance delivering a few things and sure enough he had a radar detector. I unfortunately didn't have a camera, just thought it was a bit strange and funny. Maybe I'm missing something but again, this seems very illegal. From what I understand, a radar detector is illegal in any commercial vehicle?
