Can Police Run Plates Without Probable Cause?
In today’s law enforcement landscape, the ability to quickly identify and track vehicles is a crucial tool for police officers. One way they can do this is by running a license plate (PLATE) through a database to obtain information about the vehicle and its owner. But is it legal for police to run plates without probable cause?
The Short Answer:
No, police cannot run plates without probable cause.
The Longer Answer:
What is Probable Cause?
Probable cause is a legal standard that requires law enforcement officers to have a reasonable belief that a crime has been committed or is about to be committed before they can take certain actions, such as making an arrest, searching a person or property, or obtaining a warrant.
What is License Plate Information?
License plate information (LPI) is data collected by law enforcement agencies about vehicles and their owners. This data can include the vehicle’s make, model, color, and license plate number, as well as the owner’s name, address, and other identifying information.
Can Police Run Plates Without Probable Cause?
The answer to this question is no. In the United States, the Fourth Amendment to the Constitution protects individuals from unreasonable searches and seizures. The Supreme Court has held that running a license plate without probable cause is a Fourth Amendment violation.
Riley v. California (2014)
In Riley v. California (2014), the Supreme Court held that the warrantless search of a cell phone incident to an arrest violates the Fourth Amendment. The court noted that the Fourth Amendment protects not only physical items but also digital information.
Utah v. Strieff (2016)
In Utah v. Strieff (2016), the Supreme Court held that a police officer’s stop of a motorist for a traffic violation and the subsequent search of the motorist’s car did not violate the Fourth Amendment. However, the court also noted that the officer’s stop was justified by a valid traffic violation and that the search was limited to the area of the car where the motorist was sitting.
Illinois v. Caballes (2005)
In Illinois v. Caballes (2005), the Supreme Court held that a police officer’s stop of a motorist for a speeding violation and the subsequent search of the motorist’s car did not violate the Fourth Amendment. The court noted that the officer’s stop was justified by a valid traffic violation and that the search was limited to the area of the car where the motorist was sitting.
State-by-State Variations
While the Supreme Court has consistently held that running a license plate without probable cause is a Fourth Amendment violation, some states have enacted laws that allow law enforcement agencies to run plates without a warrant or probable cause. These laws typically require the officer to have a reasonable suspicion that a crime has been committed or is about to be committed before running the plate.
