Jack’s Way goes from Lexington St to both Kennedy Middle School and Waltham High School. This is a one way road, but just north of Jack’s Way is the exit from the schools onto Lexington St. Inside the exit, the police car waits. If you are speeding along Lexington St from Totten Pond Rd to Lake St, the trees will prevent you from seeing the police SUV but the radar goes through the branches and by the time you see the officer, it will be too late. Officer has good view through the leaves.
