I was going to post this in local area, but this can happen anywhere.
They are doing a bunch of major construction on I-15 in Utah, and long stretches where the PSL is 55. Everyone is doing minimum 65, up to 75.
So I'm driving home from work, all 3 lanes moving about the same speed - due to congestion they are doing 55-60. A UHP cruiser is running C/O Ka about 100 yards ahead of me. I'm in the same lane, going the same speed, maybe 60 for a few miles.
He then turns off his radar for a mile, then back on, and pulls the guy over just ahead of him. At most he was doing 60 during a lane change - probably did not notice the cop behind him. This guy was basically going the same speed as the rest of the crowd. I think this was the LEO picking one out of the crowd, in a 55 construction zone.
Certainly it could have been for something else, but since he blasted the radar back on, and 15 seconds later lite the guy up - I figured he was just the unlucky one in the group - all going over PSL.
