New Hampshire GPS Tracking Laws: Is It Legal to Put a Tracker on a Car? (2026)

Maybe you found a strange device tucked behind your license plate. Maybe you are tempted to drop an AirTag in a spouse's car to confirm a suspicion. Either way, New Hampshire has more to say about it than almost any state in New England.

New Hampshire is one of the few states with a statute written specifically for this problem: RSA chapter 644-A, Electronic Device Location Information. It flatly bans placing a tracking device on someone else's person or property without consent.

But the statute has an unusual twist that most websites get wrong, and understanding it matters. This guide explains what RSA 644-A actually says, where the stalking law takes over, what employers can do, and what to do if you find a tracker on your car.

Is It Legal to Put a GPS Tracker on a Car in New Hampshire?

The short answer: you can track your own car, and you can track someone else's car only with their consent or under a specific statutory exception. Putting a tracker on a vehicle that belongs to someone else, without permission, violates New Hampshire law.

That rule comes from RSA 644-A:4. The statute says no individual or person shall, without consent, place, locate, or install an electronic device on the person or property of another and obtain location information from that device.

Notice the structure. The violation has two parts: installing the device on another person's body or property, and obtaining location data from it. Slipping a GPS unit under a neighbor's bumper and watching the dot move checks both boxes.

New Hampshire passed this chapter to deal directly with location tracking, so unlike states that stretch old surveillance laws to fit, the Granite State's rule is on point. The complication is what happens after a violation, which is where most summaries of this law fall apart.

RSA 644-A: A Ban With a Criminal/Civil Split

Here is the nuance that aggregator sites routinely misreport. Many claim that any GPS tracking violation in New Hampshire is a class B misdemeanor. That is not what the statute says.

RSA 644-A:6 splits enforcement into two tracks. The criminal penalty, a class B misdemeanor, applies to an individual acting for or on behalf of a government agency who violates the chapter. Think of an officer or government contractor tracking someone without a warrant or other lawful basis.

A purely private violator, like a suspicious spouse, an ex, or a nosy neighbor, does not face that class B misdemeanor under chapter 644-A. Instead, the statute gives the person who was tracked an express civil cause of action. The victim can sue the tracker directly for violating the chapter.

So is private GPS tracking "legal" in New Hampshire? No. It is unlawful, and the victim can take the tracker to court for money damages. It just is not prosecuted as a crime under 644-A itself.

That does not mean a private tracker faces no criminal risk at all. It means the criminal exposure comes from a different statute: New Hampshire's stalking law, covered below. Secret tracking that is part of a pattern of following, monitoring, or threatening someone is very much a crime in this state.

Who Can Legally Track a Vehicle in New Hampshire

RSA 644-A:3 lists the situations where tracking is allowed. They are narrow and specific:

• Consent. If the person being tracked agrees, the chapter does not apply. This is the exception that covers fleet tracking apps, shared family location services, and couples who voluntarily share locations.
• Parents and guardians of minors. A parent, foster parent, or legal guardian may track their minor child. A parent who puts a locator in a teenager's car is acting within the law.
• Guardians of incapacitated adults. A court-appointed guardian may track their ward, which matters for families caring for adults with dementia or serious disabilities.
• Court-ordered monitoring. Electronic monitoring for house arrest, probation, or parole is exempt.
• Government emergency uses. Law enforcement and emergency services can use location data in E-911 responses, emergencies, missing-minor cases, and situations with consent or other legal authorization.

Outside those categories, the default rule of RSA 644-A:4 controls: no consent, no tracking.

One practical note on vehicles you co-own. The statute speaks of the person or property "of another." Tracking a car titled solely in your own name is generally outside the ban, but a jointly owned car driven exclusively by an estranged spouse is murky territory, and a divorce court will not look kindly on covert tracking either way. In a separation, get legal advice before you act.

Can My Employer Track My Car in New Hampshire?

New Hampshire has no statute specifically governing employer GPS tracking. The general framework of RSA 644-A fills the gap, and it turns on two things: who owns the vehicle, and whether you consented.

If you drive a company-owned vehicle, your employer is tracking its own property. The ban in 644-A:4 covers placing a device on the property "of another," so a business installing GPS in its own trucks is on solid ground. Most New Hampshire employers still disclose tracking in a written policy, which is good practice and removes any doubt.

If your employer wants to track your personal car, the calculus flips. Your car is your property, so the employer needs your consent. That usually happens through a signed mileage-app agreement or telematics consent form. An employer that hides a tracker on an employee's personal vehicle without consent invites a civil suit under RSA 644-A:6 and a common-law privacy claim.

Employees who consented to tracking on a company vehicle should assume the data is collected during off-hours too unless the policy says otherwise. If that bothers you, ask whether the device can be disabled outside work time. For a broader look at monitoring on the job, see our New Hampshire recording laws guide.

AirTags, Tiles, and Item Trackers

Apple AirTags and similar Bluetooth trackers have changed who gets tracked and how. They have also given New Hampshire prosecutors a clean path to criminal charges, because of specific language in the stalking statute.

RSA 633:3-a defines stalking as a course of conduct targeted at a person that would cause a reasonable person to fear for their safety, or the safety of a family member. The statute then lists the acts that count as a course of conduct, and one of them is "placing an object on the person's property, either directly or through a third person."

An AirTag is an object. Dropping one into someone's purse, glove box, or wheel well is placing an object on their property. Combined with even one more qualifying act, like following the person or showing up where the tracker says they are, that builds a stalking charge.

Stalking in New Hampshire is a misdemeanor. It jumps to a class B felony if the person has a prior stalking conviction within the past 7 years or commits the offense in violation of a protective order. So the abusive ex who plants a tracker after being served with a stalking order is looking at felony exposure, not a slap on the wrist.

Federal law adds another layer. Under 18 U.S.C. 2261A, using an electronic device to stalk someone across state lines, or in a way that causes substantial emotional distress, is a federal felony. With Massachusetts, Maine, and Vermont all within an easy drive, cross-border tracking cases out of New Hampshire can land in federal court.

Penalties and Civil Liability

On the civil side, a tracking victim in New Hampshire has three distinct tools:

1. The express civil action in RSA 644-A:6. The statute itself authorizes the person who was tracked to sue any violator. This is rarer than people assume; many states ban tracking but give victims no direct statutory claim.
2. The intrusion privacy tort. New Hampshire recognized the tort of intrusion upon seclusion in Hamberger v. Eastman, a 1964 New Hampshire Supreme Court case, decades before most states. Covert GPS surveillance of a person's daily movements fits the intrusion framework.
3. Civil stalking protective orders. A tracking victim can petition for a protective order based on stalking conduct without waiting for a criminal charge. Violating that order then escalates any future tracking to felony territory.

For the protective order process, including emergency orders, see our guide to New Hampshire restraining order laws.

Police Tracking and Your Fourth Amendment Rights

Government tracking has constitutional limits on top of RSA 644-A. In United States v. Jones (2012), the U.S. Supreme Court held that attaching a GPS device to a vehicle and monitoring its movements is a search under the Fourth Amendment.

That means New Hampshire police generally need a warrant before placing a tracker on a suspect's car. Evidence from a warrantless tracker is vulnerable to suppression. And remember, an individual acting for a government agency who tracks outside the legal exceptions is the one person who actually faces the class B misdemeanor in RSA 644-A:6.

What to Do If You Find a Tracker on Your Car

If you discover a GPS device or AirTag you did not place, work through these steps:

1. Do not destroy it. The device is evidence, and in a criminal case it may carry fingerprints, a serial number, or account data that identifies who planted it.
2. Photograph everything. Capture the device where you found it, then the device itself from multiple angles, with timestamps.
3. Check for AirTag alerts. iPhones flag unknown AirTags traveling with you automatically; Android users can run a manual scan in settings. Save screenshots of any alert.
4. Call local police or the State Police. Report it as suspected stalking under RSA 633:3-a. Bring your photos and any history with a suspected person.
5. Consider a protective order. If you believe an ex or acquaintance planted it, a civil stalking petition can put court-ordered distance between you, and it makes any repeat tracking a felony.
6. Talk to a lawyer about a civil claim. RSA 644-A:6 gives you a direct right to sue the person who tracked you.
7. Sweep the vehicle. Check wheel wells, bumpers, the OBD port under the dash, seat pockets, and the spare tire compartment. Hardwired trackers may require a mechanic.
