Speed Measuring Devices

Updated September 30, 2014

Below is a link to each speed measuring device (SMD) certificate that we provide to defendants in cases where a speed measuring device - radar, laser, or lidar - was used. These certificates are provided here instead of sending a copy in each case where requested. Please review the certificate here, or download a copy for yourself.

Each SMD is identified by the agency (Grandview Police Department, Moxee Police Department, Selah Police Department, Tieton Police Department, Washington State Patrol, and Yakima Sheriff's Office (YSO)), the serial number for the SMD, and the date of the latest test and calibration. Each certification is valid for the manufacturer's recommended two years. The testing and calibration may nevertheless be done more often as a precaution.
