John R is a four lane road that strolls through a school town called Hazel Park from 8 Mile to 10 Mile, just south of I-696. Speed limit here is 30, and although it seems slow for those whom have just exited the freeway, KEEP TO IT! Two officers patrol the street heavily. I work nights at a restaurant facing John R and see between 2-5 people pulled over in an 8 hour period…and that’s just the 1/4 mile stretch that I can see from my window. My fiance got hit here for 34 in a 30. Most drivers do 40-45, but don’t follow suit…it’s not worth it! Lots of tickets!
