How do I know if I've been essentially caught by Speed Van?

The short version is I was driving a company vehicle through a construction zone and was going roughly five over the speed limit and from behind the cement blocks comes a big van with about 2 cameras on the back of it. Rapid flashes go off while I get semi-close to it and there's a fair amount of traffic around me going easily 20 over. And I'm wondering if I'm already boned. I was in the center lane with roughly five cars going through the same area as me easily going 65 in a 45 zone.

Frankly I'm nervous as ****
