Can South Dakota Police Search My Phone During a Traffic Stop Here's What the Law Says

During a standard traffic stop in South Dakota, police generally cannot search your phone unless one of a few specific legal exceptions applies. Here’s a breakdown of the law and your rights:

Constitutional Protections

Fourth Amendment: The U.S. Constitution prohibits unreasonable searches and seizures, meaning police cannot search your person or property—including your phone—without a warrant or probable cause.

Riley v. California (2014): The U.S. Supreme Court ruled that police generally need a warrant to search a cell phone, even if they have seized it during an arrest. This landmark decision reinforced strong privacy protections for digital devices.

Exceptions Where a Search May Be Allowed

Consent: If you voluntarily give police permission to search your phone, they do not need a warrant. However, you are under no obligation to consent, and you have the right to refuse.

Probable Cause and Warrant: If police have probable cause to believe your phone contains evidence of a crime, they can seek a warrant from a judge to search it. The judge must be convinced there is a reasonable basis for the search.

Search Incident to Arrest: While police can search your person and immediate surroundings during an arrest, the Supreme Court has clarified that this does not automatically extend to searching your phone’s contents. Even if your phone is seized during an arrest, police still need a warrant to access its data.

Practical Implications in South Dakota

You Can Refuse Consent: You have the right to refuse a request to search your phone during a traffic stop.

Seizure vs. Search: Police may temporarily seize your phone as evidence if they suspect it contains evidence of a crime, but they still need a warrant to search its contents.

State Law: South Dakota law aligns with federal protections. Any search of your phone must be supported by probable cause and typically requires a warrant unless you give consent or another exception applies.

Documentation: If you feel your rights are being violated, it is advisable to document the interaction, either by making mental notes or recording the encounter if it is safe to do so.
