If you’re pulled over in Indiana, you might wonder whether police can legally search your phone. With smartphones holding so much personal data, understanding your rights is crucial. Here’s what Indiana law (and U.S. Supreme Court precedent) say about police searches of your digital life during a routine traffic stop.
The Fourth Amendment and Digital Privacy
Both federal and Indiana law uphold the Fourth Amendment, which protects against unreasonable searches and seizures. In most cases, police in Indiana must obtain a warrant to search your phone—even if you are stopped or arrested. This requirement was cemented by the U.S. Supreme Court in Riley v. California, which stated that a cell phone search requires its own warrant, due to the vast personal information these devices contain.
When Can Police Search Your Phone?
There are only a few exceptions to the warrant requirement:
Consent: If you voluntarily let police search your phone (for example, by providing your passcode or opening it for them), they don’t need a warrant. You always have the right to refuse—politely stating “I do not consent to any search” protects your rights.
Exigent Circumstances: If officers believe immediate access is needed to prevent harm, destruction of evidence, or another emergency, they might search your device without a warrant. These situations are rare and heavily scrutinized in court.
Incident to Arrest: Even if you’re arrested, police cannot automatically search your phone. They can seize your device and apply for a warrant, but they cannot go through your messages, photos, or data without judicial approval.
What If You Refuse to Unlock Your Phone?
Generally, you cannot be compelled to unlock your phone or provide a passcode without a court order. Indiana recognizes your right not to self-incriminate, protected by the Fifth Amendment. If police ask for your code or fingerprint, you are entitled to decline unless a judge has specifically ordered otherwise.
Special Note: Vehicle and “Plain View” Searches
Indiana police need probable cause (e.g., if illegal items are visible or evidence is in plain view) to search your vehicle during a stop. However, this does not automatically extend to your phone. Phones are treated differently from other property because of their sensitive contents.
What Happens if Police Search Your Phone Illegally?
If police search your phone without a warrant (and without a valid exception), any evidence they obtain may be inadmissible in court. Indiana courts uphold the exclusionary rule, meaning unlawfully obtained evidence cannot be used to prosecute you. This is a key safeguard for your digital privacy.
New Consumer Data Protections
Indiana’s new Consumer Data Protection Act goes into effect in January 2026 and further strengthens privacy rights, although its primary focus is on businesses and data controllers—not law enforcement. Still, its passage reflects growing recognition of Hoosiers’ right to control access to personal information.
In summary:
Indiana police cannot search your phone during a traffic stop without either your consent, exigent circumstances, or a valid warrant.
You have the right to refuse consent and are not required to provide access codes unless compelled by a court order.
If officers do conduct an illegal search, evidence found may be thrown out in court.
To protect yourself, remain calm, clearly assert your rights, and ask if you are free to leave. If ever in doubt, request to speak to an attorney before handing over your digital privacy.
