How Livonia Attorneys Challenge Radar Guns in Speeding Ticket Cases

If you have ever been caught speeding by a police officer’s radar gun, you may think you have no recourse but to pay the ticket. However, although the radar guns are useful tools to detect speeding vehicles, they do have their weaknesses. Radar gun evidence can be challenged in court based on some limitations of the guns themselves.

How Speeding Ticket Radar Guns Work

Radar guns both send and receive radio signals that bounce off a vehicle using a scientific principle known as the Doppler Effect. Based on the value of the returning signal, the speed of a vehicle can be determined. Recently, law enforcement agencies have also begun using laser technology in the form of Light Detection and Ranging guns (LIDAR), which operate similarly to the more traditional radar except that they use lasers instead of radio waves.

Calibration Record Evidence in Speeding Ticket Cases

Both radar and LIDAR guns require regular calibration and adjustment. Radar guns are calibrated through the use of tuning forks to ensure accurate readings. The recommended frequency of calibration is prior to each use according to the manufacturer; however, many jurisdictions have more lenient policies and the devices tend to be calibrated far less frequently.

This creates an avenue for attorneys to challenge radar gun evidence. Calibration records for the device are requested, and if there is a discrepancy as to the recommended calibration schedule and when it was actually calibrated, the attorney can argue that the judge should dismiss your violation. Similarly, if a radar device is not calibrated correctly (i.e., it was calibrated without the actual use of a tuning fork), an argument can be made that the ticket is based on false evidence and should be dismissed.

Challenging Radar, LIDAR Training in Speeding Tickets

Any officer using radar or LIDAR technology in Michigan must go through a training and certification program before operating the device. Our attorneys generally request certification records for the ticketing officer, and if the officer is not properly certified, an argument can be made that the elevated reading was a result of operator error.
