This is another "School Zone" speed trap. While heading north on Jerusalem towards Old Country rd, as you approach 4th street, you enter a school zone that goes from a 40 to a 20. The cops hide out on that corner and jump out to make you turn into 4th street. They usually have several more cars pulled over at that point. P.S.—Dont forget the Red Light camera at Old Country road. It would be a shame to get a seeding ticket and then one block away get a red light ticket mailed to you. Drive safe.
