Police Traffic Stop in PennsylvaniaThe Fourth Amendment of the United States Constitution holds that every individual has a right to live free from unreasonable search and seizure by law enforcement. The founding fathers were concerned about unfair bodily and home searches while drafting this amendment. In modern times, there has been extensive debate about whether this right extends to a driver and his vehicle. One case concerning the legality of motor vehicle searches reached the U.S. Supreme Court in 2009. The Supreme Court’s decision laid out the ways in which this amendment should be applied to different traffic stops, and it has become a foundation for understanding the Fourth Amendment in the context of drivers on the road.

Probable Cause for a Traffic Stop in Bucks County, Pennsylvania

The Court’s decision allows warrantless searches, depending on the cop’s reasons for stopping the motor vehicle. When a police officer has already established that the driver is under arrest, they can search the vehicle. When an officer has probable cause that evidence of a crime will be found, a search can be conducted. In addition, police searches of a car are legal when evidence of an illegal activity is in plain view or when the driver consents to a search. A police officer who doesn’t have any legal basis to search your vehicle will often ask for consent, and you don’t have to comply.
