Police Traffic Stops The facts contained below considers the major elements that institute a traffic stop as being defensible and legally professional. It will also consider the case laws that established the legality of check points and traffic stops.

A traffic stop usually occurs when a law enforcement agent signals a motorist to stop by the roadside (Traffic Stops and Roadblocks-Lawyers.com). This stop comprises a seizure under the Fourth Amendment because it stands in the way of the freedom of movement of the motorist. For this stop to be valid under the Fourth Amendment of the United States Constitution, the law enforcement agent must look at specific and expressed facts to lend support to probable cause of criminal conduct or reasonable suspicion.

Inconsistent driving behavior, like drunk or reckless driving

Emergency response calls

Apprehensive criminal activity
