Just in the last couple of days I have noticed on my 30mi commute, my RD detecting K-band every mile (on and off) for 6-8 miles straight. I quickly realized that this was is in an area on either side of an interchange (that they are about to begin an overhaul). I've found that there are construction signs on trailers in the areas where the alerts occur. Before you say, well DUH! Here's the deal, as of now these signs are turned or facing parallel to the road. The message on the signs are "TEST 800" "TEST 801" etc. Has anyone else experienced this? Are they just surveying speeds now before construction or will they eventually turn the signs to face the road? I have never seen radar equipped signs in the metro area. Just have seen them in southern OK on the way to Dallas.
I did some research on these signs and I think they are CMS (changeable message signs) that have software to be able to display different messages depending on radar readings. Makes me wish I still had my Crapra to see if these have SWS or not
