Cops usually work with a pair of hardly marked, dark blue sedans, running Ka-band radar. Ann Arbor cops’ favorite spot is eastbound on M-14 as Barton Dr. exit is approached, just as speed limit has dropped from 70 to 55 MPH. Cop cars like to park close to concrete median, barely visible until usually too late to slow down. Be aware they can catch you in both directions, since run Ka radar, front and back antennas. Most likely will be operated morning rush hour to about noon, although expect just about any time of day. Ann Arbor is a notorious speed trap town, drained of funds, and the cops are tax collectors, instead of using the police to keep businesses and neighborhoods safer from crime.
