You are a police officer more than likely working for the highway state patrol when a car driving much faster than the posted speed limit zips by where you are radaring. Go get him! At a high rate of speed you will need to bob and weave through the highway of vehicles that are pulled over on the side of the road so that you may pass and get the fast driving criminal. You will need to use your police academy defensive driving skills in order to apprehend the driver and put him into custody.
