Is it true in new jersey/new york that they have speed tracking cameras on their major interstates?? A lady came into my store a week ago and said she got a ticket in new jersey for speeding on the highway. It was sent to her by mail. She said her radar detector goes off when she passes these cameras on the highway. I thought she was joking at first, but she showed me the ticket. I thought it was illegal to put speed device cameras on major interstates?
