According to United States v. Jones, the use of GPS tracking constitutes a search due to which factor?

• A. The device itself triggers a search
• B. A warrant is required regardless
• C. Placement of the GPS device constitutes a physical trespass
• D. Prolonged tracking alone constitutes a search

Answer: (C)

The key idea is that a Fourth Amendment search can arise from a physical intrusion into property to obtain information. In United States v. Jones, the Supreme Court held that attaching a GPS tracking device to a suspect’s vehicle and using it to monitor its movements is a search because it involved a physical trespass onto the vehicle to place the device in the first place. That act of placement is what triggers Fourth Amendment protections, not merely how long the vehicle is tracked or whether a warrant would be required in another context. So the critical factor is the physical trespass involved in placing the device on the vehicle.
