Usually the last week every month during rush hour times 9am and 4pm, they stage a full blown trap. One cop sits off to the right hidden on a hill overlooking Northbound traffic (traffic heading toward New Brighton) in the 50mph zone. Meanwhile they have 2-3 patrol cars up the road with emergency lights on already in the 50mph zone before the 40mph zone. They have one lane closed, which causes a complete slow down in traffic. The cop on the hill radios to the other cops on which cars were speeding. When you drive up (at nearly 5mph) they will signal you to pull over if you were tagged or wave you on if you weren’t. Today a friend of mine was one of the people they instructed to pull over. Officer said he was doing 50mph (which the speed limit says 50mph) but he was in a "construction" zone. There are no such signs on that side of the road, just the 50 mph speed limit, however there are construction signs for the southbound side. I suppose they just randomly pull anyone over and make the reasons up.
*** tip for avoiding a ticket – stay in the right lane and this makes it harder for the cop on the hill to see you!
