When the "Men in Black" show up at your house at 3:00am to talk to you (or drag you away), you'll know just how good your decision was. By the way, sleep well.

So you're saying sleep with my AR tonight? LOL!

That is why I am trying to figure out the license plate numbers.

They were either criminals trying to jack with the public or officers maneuvering their undercover vehicles in an unsafe manner (per your description).

Anyone can wear body armor, it just increases your charges if you commit a crime while wearing it.

^^^^ This.

Absolutely not. There were 4 vehicles like this, unmarked and and stopping traffic, trying to herd vehicles over to the right lane. One got out and directed people over into the next lane for 2 cars, then walked back into his car and drove off. After he drove off I went into one of the two turning lanes and turned left. There was still one of these unmarked vehicles in the middle of the lane blocking traffic. He stayed in his vehicle with lights on and never got out. When he saw me turn in the turning lane he followed me. I signaled and turned into the right lane with the rest of the backed up traffic. He pulled right in front of me and turned sharply, cutting me off. 3 vehicles behind me went past and he then pulled out and went down the open left lane. NEVER did he get out of his vehicle to question me, even after I laid on my horn and opened my truck door.
So, I followed his lead and went down the free lane. Next light, he parked in the middle of traffic and prevented cars from crossing during the light and the traffic in the right lane continued through the light. At Lincoln and I-25 he did the same thing. The sheep in the right lane all turned onto to the highway going south on the highway, in single file. I drove around his car to the right and continued East on Lincoln. Not one of the 4 vehicles with lights followed me.

Seemed a bit odd to me. All of their plates ended in URC, though I only got two whole numbers. That is why I am asking.

Could it have been a construction company trying to move traffic or blockers for oversized loads...which are authorized to do so?

And undercover/vice type cars aren't going to deal with stuff like this

[theGinsue]

Aren't construction companies, etc. supposed to have orange lights in cases like this?

Please correct me if I read something into this that wasn't said or implied, but it sounds like these cars had red/blue lights running - which are reserved for official emergency vehicles only; right?

UCR=Unified Carrier Registration?
This sounds like Dept. of Transportation.... maybe?

A lot of them are getting private security or off duty cops to use the construction companies red/blue lighted cars...which they can get permission to use. Basically construction companies started figuring out that people will actually slow down for red/blue lights and reduce the risk of killing them while working.

Secret service will usually have a uniformed escort as well. Don't know about here, but they usually send cars or motorcycles ahead to block intersections so the motorcade can continue driving and not stop
