Utah police cannot search your phone during a traffic stop without a warrant or your consent. This protection is rooted in both Utah state law and federal constitutional law:
-
Utah’s Electronic Information or Data Privacy Act specifically bars law enforcement from searching the contents of your phone or other electronic devices without a search warrant, except in very limited circumstances. This law covers all data stored on or transmitted from your phone, including texts, emails, photos, and location information.

Exceptions: Police may only search your phone without a warrant if:
-
You give informed consent.
Advertisement -
There is a true emergency (for example, to locate a missing person in danger).
-
The phone was reported stolen.

A judicially recognized exception to the warrant rule applies (these are rare and closely scrutinized).
-
-
Federal Law: The U.S. Supreme Court has ruled that police generally must obtain a warrant to search a cell phone, even after an arrest. This means the Fourth Amendment protects your phone from search during a routine traffic stop unless you consent or a rare exception applies.

Passcodes and Access: Even if police have a warrant, Utah’s Supreme Court has ruled that you cannot be compelled to provide your phone’s passcode; you have a Fifth Amendment right to refuse to unlock your device for law enforcement.
