How Missouri Police Determine Speeding

Radar and Laser detection devices are the most widely accepted methods used by law enforcement to detect a driver’s speed.  Using these devices, an officer is able to record your speed by targeting your car, specifically.  These devices must be calibrated properly, however, leaving them vulnerable to rebuttal.


However, a driver can also be cited for ‘Careless and Imprudent Driving’ if he or she is driving too fast or too dangerously for the current road and weather conditions.  In this case, the officer can observe the driving behavior and issue a citation for it.
