Putting a tracker on someone else’s car without their consent can be a crime, and in some states the vehicle tracker is named in the statute itself. California bars using an electronic tracking device to determine a person’s location or movement, and Texas makes it a Class A misdemeanor to knowingly install one on a vehicle owned or leased by another person. At the federal level, stalking law reaches surveillance done with intent to harass or intimidate. This article reads those texts, then covers what to do if you are the person being tracked. It is general information, not legal advice.
What the federal stalking statute says
The federal stalking law, 18 U.S.C. 2261A, does not mention trackers by name. Its second paragraph covers a person who, “with the intent to kill, injure, harass, intimidate, or place under surveillance with intent to kill, injure, harass, or intimidate another person,” uses the mail, an interactive computer service, an electronic communication service or system, or any other facility of interstate or foreign commerce to engage in a course of conduct. The penalties are those provided in section 2261(b) or section 2261B.
That is a statute with conditions, and the conditions matter. It turns on intent and on a “course of conduct” carried out through a facility of interstate commerce. Whether a given tracker placement meets them is a question of facts that a prosecutor and a court decide, not something a web page can settle. What the text does show is that “place under surveillance” with the intent to harass or intimidate is within its reach.
California and Texas name the device
State law is more direct. The California Penal Code section 637.7 says no person or entity in the state shall use an electronic tracking device to determine the location or movement of a person. It carves out exceptions, including one where the registered owner, lessor or lessee of a vehicle has consented to the device being used on that vehicle, and one for lawful use by law enforcement. A violation is a misdemeanor.
The Texas Penal Code section 16.06 defines an electronic or mechanical tracking device as a device capable of emitting an electronic frequency or other signal that may be used to identify, monitor, or record the location of another person or object. The offense is knowingly installing one on a motor vehicle owned or leased by another person, and it is a Class A misdemeanor. Defenses include written consent of the owner or lessee, assisting a peace officer, and a licensed private investigator acting with consent and court authorization.
A note on sources: the official sites for both statutes were not readable in a way that allowed a clean check, so the text above comes from the public.law mirrors. Before you rely on a statute for a real decision, read the current version on the state’s own site or ask a lawyer, because statutes are amended.
| Law | What it targets | Notable exception or defense | Penalty stated |
|---|---|---|---|
| 18 U.S.C. 2261A | Course of conduct with intent to harass, intimidate or surveil, via interstate commerce | Turns on intent | As provided in 2261(b) or 2261B |
| California Penal Code 637.7 | Using a tracking device to determine a person’s location or movement | Vehicle owner, lessor or lessee consent; lawful law enforcement use | Misdemeanor |
| Texas Penal Code 16.06 | Installing a tracking device on a vehicle owned or leased by another | Written consent; assisting an officer; licensed investigator with consent and court authorization | Class A misdemeanor |
Other states have their own rules, and the wording varies. The reference on GPS tracking laws by state is the place to start for a state not covered here.
Why an AirTag is not a loophole
Some people assume a small Bluetooth tag is a gray area because it is sold for keys and bags. The statutes above do not turn on the brand or the marketing. California speaks of an electronic tracking device used to determine a person’s location or movement, and Texas speaks of a device capable of emitting a signal that may be used to identify, monitor, or record location. The purpose and the target are what count. Neither text promises that a consumer product falls outside its definition, so treat that as an open question for a lawyer, not as a loophole.
The tags also fight back. Apple’s unwanted-tracking page says an iPhone can alert a person when an AirTag that is separated from its owner is seen moving with them over time, with alerts named “AirTag Found Moving With You”, “AirPods Detected” and “Unknown Accessory Detected”. Separated devices also play a sound. Apple and Google collaborated on an industry specification for these alerts. The point is that Apple built a warning path for the person being moved with a tag.
If you think a tracker is on your car
Start with your own safety, not the device. The Department of Justice defines stalking as engaging in a course of conduct directed at a specific person that would cause a reasonable person to fear for their safety or the safety of others, or to suffer substantial emotional distress. The DOJ Office on Violence Against Women says to contact local law enforcement or the National Center for Victims of Crime at 855-4-VICTIM (855-484-2846). If you are in immediate danger, call 911.
The Federal Trade Commission has guidance on a related problem, stalkerware on phones, and its safety advice carries over in spirit. Its stalkerware article says to think about your safety first, warns that removing spyware could tip off an abuser, suggests using a borrowed or prepaid device for sensitive searches, and points to the National Domestic Violence Hotline at 1-800-799-7233, with chat at thehotline.org and a text option, START to 88788. A domestic violence advocate can help with a safety plan. That article is about phone spyware, not vehicle trackers, so the reading here is an application of its logic, not a statement from the FTC about tags.
For finding a device, two existing guides cover the practical side: how to check your car for a GPS tracker and common places trackers get hidden on a car. If you do find something and the situation involves a partner or former partner, consider talking to an advocate or police before you remove it. That is judgment, not a rule from a statute, but it follows the FTC’s caution about tipping someone off.
Our take
Do not put a tracker on a car you do not own or lease without the owner’s consent. State statutes such as California’s and Texas’s name the act, and federal stalking law reaches surveillance done to harass or intimidate. If you are the one being tracked, call the police, the National Center for Victims of Crime or the domestic violence hotline, and call 911 in immediate danger.
Common questions about trackers on other people’s cars
Is it legal to put a tracker on my own car?
The Texas statute covers a vehicle owned or leased by another person, and California’s exception covers the registered owner, lessor or lessee who has consented. Rules differ by state, so check yours.
Does a tracker on a car I co-own or lease count?
Both statutes turn on ownership, lease and consent. Co-ownership and shared leases are fact-specific, so ask a lawyer before relying on them.
Who do I call if I find a tracker I did not place?
Local law enforcement, or the National Center for Victims of Crime at 855-4-VICTIM. Call 911 if you are in immediate danger.
Can a private investigator place a tracker?
Texas lists a defense for a licensed private investigator with consent and court authorization. That is a narrow defense and it is not available to a private person.
