Police are using stationary laser guns sometimes known as lidar guns, to enforced speed limit laws and issue traffic speeding tickets. These traffic speeding tickets might turn into probable cause traffic stops for future enforcement. 

Notice, the police officer is stationary on the right side of the zebra strips aiming the laser gun at on coming traffic.   

Laser / Lidar (Light Detection and Ranging) devices are instruments utilized to measure vehicle speed by analyzing the time required for a laser beam to reflect back from the vehicle.

The following is an overview of the typical process involved:

* Stationary Position

* Operation of the Lidar / Laser Device

* Issuance of Citations / Speeding Tickets / Violations (if necessary)

* Establishing Probable Cause for Traffic Stops

* Legal Considerations

In summary, the application of lidar / laser technology aims, which may not be operated property to improve road safety by enforcing speed limits.
