As surveillance tools become more advanced, GPS tracking has become a critical part of private investigations — especially in cases involving suspected infidelity, child endangerment, public safety concerns, and no-contact order violations. Idaho does not currently prohibit licensed private investigators from using GPS devices, but it’s important to understand the limits.
✅ Idaho Law: No Direct Ban on GPS Use
Idaho does not have a specific law banning private investigators from using GPS tracking devices. That means it remains legal under state law, provided investigators stay within acceptable boundaries of conduct and don’t violate broader privacy or stalking laws.
Idaho Code § 18-6702, which covers electronic communications, doesn’t restrict GPS placement unless it falls under unlawful interception or surveillance. As of now, GPS tracking data collected in public spaces is generally considered legal — especially when it aids an ongoing investigation.
🧭 Legal Precedent: Idaho v. Danney (2010)
The case of State v. Danney (Court of Appeals, Idaho, 2010) helps clarify what courts consider acceptable. Law enforcement had placed a GPS tracker on a suspect’s vehicle without a warrant. The court ruled it was not a violation of the Fourth Amendment because the vehicle was in a public place, and the data collected involved movement on public roads.
Although this case involved police, the same reasoning supports private investigators operating within lawful bounds.
🚗 When Is GPS Tracking Justified?
Private investigators may use GPS tracking for several legitimate purposes, including:
Suspected infidelity or adultery
Child custody and child endangerment cases
Suspected abuse or no-contact order violations
Uncovering dangerous driving patterns
Business-related monitoring (e.g., tracking employee vehicle misuse)
Ensuring the safety of a vulnerable person
These cases often involve public interest and safety concerns, especially when traditional surveillance may not produce timely or safe results.
📍 Best Practices for Investigators Using GPS in Idaho
1. Use Only in Publicly Accessible Areas
Install GPS devices while the vehicle is parked in a public space — such as a street, parking lot, or any location not clearly marked as private or fenced. Avoid entering garages, gated areas, or private driveways.
2. Do Not Trespass to Place the Device
Even if the subject is under investigation, entering private property without permission remains illegal. All tracking device placement should occur from legally accessible positions.
3. Maintain Detailed Documentation
Log the date, time, location, and purpose of each GPS placement. This information can support your actions if questions arise in court.
4. Monitor Behavior, Not Just Location
Use GPS data to support broader patterns — like regular visits to restricted areas, suspicious meeting locations, or erratic travel that may indicate risk.
5. Avoid Misuse or Harassment
Do not use GPS for personal reasons or in a way that might be interpreted as stalking. Your actions should always serve a clear investigative purpose.
⚖️ What About Consent?
While some states may suggest consent, Idaho does not require it for private investigators operating within the law. In many cases — such as investigating someone breaking a no-contact order or putting children in danger — seeking consent would compromise the investigation entirely.
As long as the vehicle is in a public space and no trespassing occurs, GPS tracking remains a powerful and legal tool when used correctly.
✅ Summary: Know the Law, Use GPS Wisely
GPS tracking is legal in Idaho when placed in public or accessible areas
State v. Danney supports public-space GPS use without a warrant
Investigators can use GPS for infidelity, custody, protection, and other active cases
Avoid trespassing or stalking behavior
Consent is not legally required, but actions must serve a lawful and justifiable purpose
