Connecticut General Statutes Title 14. Motor Vehicles. Use of the Highway by Vehicles. Gasoline § 14-219c. Use of speed monitoring devices to support a conviction

A prima facie presumption of accuracy sufficient to support a conviction under section 14-219 will be accorded to a radar, speed monitoring laser, vascar device or any other speed monitoring device approved by the Commissioner of Emergency Services and Public Protection only upon testimony by a competent police officer that: (1) The police officer operating the radar, laser, vascar device or other device has adequate training and experience in its operation; (2) the radar, laser, vascar device or other device was in proper working condition at the time of the arrest, established by proof that suggested methods of testing the proper functioning of the device were followed; (3) the radar, laser, vascar device or other device was used in an area where road conditions provide a minimum possibility of distortion; (4) if moving radar was used, the speed of the patrol car was verified; and (5) the radar, laser, vascar device or other device was expertly tested within a reasonable time following the arrest, and such testing was done by means which do not rely on the internal calibrations of such radar, laser, vascar device or other device.
