The Highway Patrol measures speed in one of four ways:
- Radar - Doppler radar's with moving and stationary capabilities mounted inside the patrol vehicle.
- LIDAR - Hand-held laser speed measuring devices that are used in a stationary position.
- Aircraft - Speed is calculated using a time and distance formula.
- Pacing - Certified, calibrated speedometers in patrol vehicles are used to match the speed of the violator's vehicle.
