There is a misconception that officers must allow drivers to see the RADAR before a citation is issued. The truth is, the officer is required to offer you an accuracy check of the RADAR prior to issuing the citation, but they are not required to show you the unit. The accuracy check consists of internal self-checks of the unit followed by measurement tests with calibrated tuning forks. RADAR units do not provide print outs of the accuracy check results.
If you are being charged with speeding based on LIDAR/LASER, the officer is not required to show you the unit here either. Further, the courts have taken judicial notice of the accuracy of these units, so field tests of the accuracy are not required either. The LASER unit is tested at the beginning and end of the officer's shift by aiming the unit at an object at predetermined distances - 100 and 200 feet respectively.
