Most states let you put a GPS tracker on a vehicle you own without restriction, no matter who’s driving it. A smaller group, including New York, California, Florida, Delaware, Hawaii, and Illinois, have passed laws that specifically criminalize placing a tracker on someone else’s vehicle without their consent, on top of the general stalking statutes every state already has. As of 2026, check your specific state’s current statute before assuming anything, since this is an area lawmakers keep amending.
Verdict
Ownership beats geography for the vast majority of tracking questions: your car, your call, in nearly every state. The six states above add a specific tracking-device statute on top of general stalking law, which mostly matters if you’re tracking a vehicle that isn’t yours. Read the actual text of your state’s law before relying on a summary, including this one.
We get asked “is this legal in my state” more than almost any other question on this site. The honest answer is that state-by-state GPS tracking law is a patchwork, built mostly on top of older stalking and harassment statutes rather than a single federal standard. A few states went further and wrote GPS-specific language into their books. Here’s how to think about where you stand.
Does GPS tracking law vary that much by state?
Less than people assume, actually. The foundational rule is nearly universal: tracking a vehicle you own outright is legal everywhere, and tracking a vehicle someone else owns without their knowledge generally isn’t. What varies is how explicitly a state’s criminal code names GPS trackers specifically versus folding the behavior into a broader stalking or electronic surveillance statute. Both approaches can result in criminal charges. The difference is mostly about how a prosecutor charges the case, not whether the underlying conduct is illegal.
Our GPS tracker guide covers the ownership principle in full if you haven’t read it yet, since everything on this page builds on that foundation.
Which states have laws specifically about GPS trackers?
New York, California, Florida, Delaware, Hawaii, and Illinois are the states most often cited for having statutory language that names electronic tracking devices directly, rather than relying purely on general stalking law to cover the conduct. That doesn’t mean tracking is legal everywhere else and illegal only in these six. It means these six have gone out of their way to spell out tracking-specific penalties, which can matter for how a case gets charged and prosecuted.
| State | Dedicated tracking statute? | What it generally targets |
|---|---|---|
| New York | Yes | Non-consensual placement of a tracking device on another person’s property |
| California | Yes | Using an electronic tracking device to determine another person’s location without consent |
| Florida | Yes | Tracking a person’s location via electronic device as part of stalking law |
| Delaware | Yes | Unauthorized installation of a tracking device on a vehicle |
| Hawaii | Yes | Electronic tracking as a form of harassment or stalking |
| Illinois | Yes | Unauthorized video and electronic tracking, addressed together in state code |
| Most other states | Not by name | Covered under general stalking, harassment, or unauthorized surveillance law instead |
We’re deliberately not citing specific statute numbers or penalty ranges here. Those change with legislative sessions, and a wrong number printed on a blog post is worse than no number at all. If you’re in one of these six states and the situation involves tracking someone else’s vehicle, read the current code yourself or talk to an attorney rather than relying on any secondhand summary, ours included.
Does it matter if the vehicle is registered jointly?
This is where things get genuinely murky, and it’s not something a state-by-state list can fully resolve. A car titled to both spouses, for instance, complicates the ownership question that usually settles everything else. Some jurisdictions treat a joint owner’s consent as sufficient on its own. Others weigh marital privacy expectations differently, particularly if a divorce or separation is already underway. If you’re in that specific situation, this is a case where “talk to a family law attorney” isn’t boilerplate, it’s the actual right move, since the answer depends on facts a general article can’t account for.
How does this apply to tracking a teenager’s car?
Differently than tracking an adult, and generally more permissively. A parent or legal guardian tracking a vehicle titled to them, driven by their minor child, sits on the “your car, your call” side of the line in essentially every state, including the six with dedicated tracker statutes, since those laws target non-consensual tracking of someone else’s property, not a parent’s own vehicle. We cover that scenario, including the rarer case of a car titled to the teen alone, in is it legal to track your teenager’s car.
What about tracking that isn’t vehicle-related?
Everything above focuses on vehicles specifically, since that’s the most common real-world scenario people ask about. GPS and location tracking law intersects with a much wider set of statutes once you move beyond cars, covering things like tracking apps on a shared phone plan or a tracker slipped into a bag. Our surveillance laws overview covers that broader landscape, including how tracking law relates to audio and video recording consent rules, which trip people up just as often.
Picking a tracker once you know where you stand legally
Once the legal question is settled, the practical one is just picking hardware. If you want a live feed and geofence alerts, a cellular tracker with a monthly plan, something like Tracki or the Spytec GL300, is the way to go. Both report location in something close to real time and can alert you the moment a vehicle crosses a boundary you’ve set.
If real-time visibility isn’t essential and you’d rather skip the recurring bill, GPS trackers with no monthly fee covers the SD-card and Bluetooth alternatives, along with what you give up by going that route. Either way, the legal analysis above doesn’t change based on which device you end up buying. Ownership and consent decide legality, not the sticker price or the update frequency of the hardware sitting in the glovebox.
Is it illegal to put a GPS tracker on someone else’s car?
In the large majority of states, yes, if you don’t own the vehicle and the owner hasn’t consented. Six states, New York, California, Florida, Delaware, Hawaii, and Illinois, have laws that name tracking devices specifically, and every state’s general stalking or harassment statute can also apply.
Which states have specific GPS tracking laws?
New York, California, Florida, Delaware, Hawaii, and Illinois are the states most commonly cited for statutes that name electronic tracking devices directly. Most other states still prohibit non-consensual tracking, just through broader stalking or surveillance law rather than tracker-specific language.
Can I get in trouble for tracking my own car?
No. Tracking a vehicle you own outright is legal in every state we’re aware of, regardless of who’s driving it. The laws discussed here target tracking someone else’s property without their consent, not monitoring your own.
Do these laws apply to tracking apps on a phone, not just car trackers?
Often, yes, though the specific statute that applies can differ from vehicle-tracking law. Location tracking through a phone app raises separate consent questions covered under broader electronic surveillance and stalking statutes, which our surveillance laws overview addresses in more detail.
State law changes more than people expect, particularly in this area. Bookmark your state’s current statute page rather than trusting any single summary indefinitely, this one included, and re-check before you install anything on a vehicle that isn’t clearly yours.
