Probable Cause Traffic Expert Witness

Law enforcement officers are utilizing traffic violations, including non-compliance with traffic control devices (such as traffic signals and stop/yield signs), improper vehicle equipment (including non-functioning directional signals, taillights, and headlights), and exceeding the speed limit as grounds to initiate a motor vehicle stop, as determined by police officers that are experts in the field. These violations are used to establish probable cause for the traffic stop.
