Travelers on NW 34th St between NW 16th Ave and NW 39th Ave need to be extra careful. Officers hide in driveways and an entrance to a subdivision. There is a hill so if you pick up speed plan on getting a ticket. The posted speed is 40 but I know people who have been ticketed doing 39 to 42 mph. After receiving the tickets, they had there speedometers checked and they were right on the money. With the tax cuts etc. I would imagine there will be a lot more tickets to drum up revenue._
