Police Radar Use – Breakdown by State, County and More

Written by Gregory Monte.

Last week I wrote a post about my personal experience with police radar in the three states I travel through every day: New York, New Jersey & Pennsylvania.

Police Radar in New Jersey, New York and Pennsylvania – Get a radar detector to avoid a speeding ticket.

I had no idea that there was a website that provides this information for every single state.  This site even breaks down police radar use on a county basis, so you can find out what specific band (X, K, Ka, Laser) you need to watch out for as you drive locally.

Update for Pennsylvania Readers

I made the claim in my post last week that the Pennsylvania State Police only use K-Band radar.  This is no longer true.  According to RDFGS, Ka-Band is now used on the Blue Route (476) near the exit for Route 76.

I also found out that Pennsylvania may soon be using Laser to detect speed, however, this will not go into effect until later this year.  According the Pennsylvania Bulletin, Volume 49:

“Permanent Regulation for LIDAR for State Police and Automated Enforcement Systems, 67 Pa. Code Chapter 205, Fall 2019, as Proposed.  The Department will be promulgating a regulation to define proper testing and calibration of LIDAR System to be used by state police and automated enforcement systems.”
