Police in Michigan generally cannot search your cell phone during a traffic stop without a warrant or your consent. Here’s how the law works:
Legal Requirements for Cell Phone Searches
- Warrant Requirement: Following the U.S. Supreme Court’s 2014 decision in Riley v. California, police must obtain a warrant to search the contents of a cell phone, even if the phone is seized during an arrest. Michigan law and its state constitution—amended in 2020—explicitly require a warrant to access electronic data and communications, placing cell phones on par with a person’s home in terms of privacy protection.
- Exceptions: There are a few exceptions where police may search your phone without a warrant:
- Consent: If you voluntarily give permission, police may search your phone.
- Exigent Circumstances: If there is an immediate threat to public safety or evidence is at risk of being destroyed, police may search your phone without a warrant (though this is rare in routine traffic stops).
- Incident to Arrest: Police may search an arrestee’s person and immediate surroundings for weapons or evidence, but this does not typically extend to a full search of a cell phone’s contents after the Riley decision.
What Happens During a Traffic Stop?
- You Are Not Required to Unlock Your Phone: Police cannot compel you to unlock your phone or provide your password unless they have a warrant or you give consent.
- Refusal Is Your Right: You have the right to refuse a request to search your phone. If police insist, you may ask if they have a warrant.
Recent Developments
- Michigan’s Constitution: Since 2020, Michigan’s constitution specifically protects electronic data and communications from unreasonable searches and seizures, requiring a warrant that describes what is being searched for and is supported by probable cause.
- Scope of Warrants: Recent Michigan court decisions have emphasized that search warrants for cell phones must be specific and not overly broad. Police cannot conduct a limitless search of your entire phone unless the warrant clearly permits it.
Summary Table

| With your consent | Yes | You can withdraw consent at any time |
| Exigent circumstances | Yes (rare) | Immediate threat to safety or evidence |
| Incident to arrest | Limited | Only for weapons/evidence, not full phone |
| With a warrant | Yes | Must be specific and supported by probable cause |
