GPS Tracker for Rental Car – What You Need to Know Before You Rent
GPS Tracker for Rental Car — What You Must Know
Before you pick up your next rental car, there is something important you should know. Every major rental car company in the US uses GPS tracking technology on their fleet — and the data they collect may surprise you. This guide tells you exactly what they track, what they are legally allowed to do with that data, what your rights are as a renter, and what happens if you try to block their tracking.
Have GPS Trackers in
Enterprise, Hertz, Avis, Budget, National, and Dollar all use GPS tracking on their entire US fleets. This is disclosed in the rental agreement — usually in the fine print most renters never read.
What Do Rental Companies Actually Track?
Rental car GPS systems are significantly more sophisticated than a simple location tracker. Here is what major rental companies collect on every trip:
🏎️ Speed data — Many companies track vehicle speed continuously. Some have policies to charge additional fees if the vehicle is driven over a specific threshold (commonly 79–90 mph) for extended periods.
⛽ Fuel level — OBD-integrated systems can monitor fuel consumption and flag discrepancies to verify fuel return policies.
🗺️ Geographic boundaries — Most rental agreements prohibit taking vehicles across state lines or international borders without prior authorization. GPS data enforces these restrictions and can trigger additional charges or contract violations.
🔧 Vehicle health data — Engine codes, mileage, and diagnostic data are collected to monitor vehicle condition throughout the rental period.
⏰ Trip timestamps — Exact departure and return times, distances driven, and driving patterns are logged for billing and insurance purposes.

GPS ActiveYour Rights as a Renter — What They Can and Cannot Do
⚖️ What Rental Companies Can Legally Do
- ✅ Track location of their own vehicle at all times during the rental period — they own the car
- ✅ Use GPS data to verify fuel return policies and charge accordingly
- ✅ Charge fees if the vehicle is taken outside authorized geographic areas
- ✅ Use speed data to verify accident circumstances and resolve disputes
- ✅ Use GPS data to recover stolen vehicles
- ✅ Share GPS data with law enforcement when legally required
🚫 What Rental Companies Generally Cannot Do
- 🚫 Charge speed-based fees in states where this has been found to violate consumer protection laws without clear advance disclosure
- 🚫 Track your location after the rental period has ended and the vehicle has been returned
- 🚫 Share personal driving data with third-party advertisers without consent in states with strong privacy laws
- 🚫 Use GPS data to impose undisclosed fees not mentioned in the rental agreement
Can You Block or Disable Rental Car GPS Tracking?
Technically yes — GPS signal blockers exist. But doing so is almost always a bad idea for three important reasons.
1. It likely violates your rental agreement. Tampering with or disabling any vehicle tracking system is explicitly prohibited in virtually all rental agreements. Doing so can void your rental insurance, make you personally liable for any incidents during the rental, and result in contract termination fees.
2. It may be illegal. Using a GPS jamming device is illegal under FCC regulations in the United States. Possession and use of signal jammers can result in federal fines of up to $100,000 and device confiscation.
3. You lose theft protection. If the rental car is stolen while a jammer is in use, the company cannot recover the vehicle via GPS — and your liability for the full value of the car may significantly increase.
What Happens if You Drive Outside Authorized Areas?
Most rental agreements restrict vehicles to specific geographic areas. Common restrictions include no travel outside the continental US without authorization, no crossing into Mexico or Canada without a specific international agreement, and in some cases no travel to specific high-theft metropolitan areas. When GPS detects a vehicle outside its authorized zone, the rental company typically issues a fee ranging from $25 to $500+ per incident depending on the company and distance traveled.
Installing Your Own GPS Tracker on a Rental Car
This is a question many travelers ask — particularly those concerned about having their own backup location data if an accident occurs. Placing a GPS tracker in a rental car you are renting is legal in all 50 states since you have authorized possession of the vehicle. However, you cannot permanently attach anything to the car (such as a magnetic tracker under the chassis) without potentially violating the rental agreement's terms about modifying the vehicle. Placing a portable GPS tracker inside the cabin or in the glove compartment is generally acceptable.
If you want to track a rental car for personal safety or trip documentation purposes, a portable tracker like Tracki Mini or Family1st placed inside the vehicle is the most practical approach. Our top recommendation for your own vehicle remains Bouncie GPS for the OBD port — but since rental cars are short-term, a portable battery tracker is more appropriate.
For your personal vehicle: real-time tracking, crash detection, no contract. Only $8–$9/month.

Do all rental cars have GPS trackers in?
Yes. All major US rental car companies — including Enterprise, Hertz, Avis, Budget, National, and Dollar — use GPS tracking technology on their entire fleet. This is disclosed in rental agreements, typically in the fine print. The tracking data is used for vehicle recovery, dispute resolution, fuel verification, and geographic boundary enforcement.
Can a rental car company track your speed?
Yes — most major rental companies collect speed data as part of their telematics systems. Whether they use this data to charge additional fees depends on the company and the specific rental agreement. Since the Acme Rent A Car controversy, companies that do charge speed-based fees are required to disclose this clearly in the rental terms. Always read the full rental agreement before signing.
Can you put a GPS tracker in a rental car?
Yes — placing a portable GPS tracker inside a rental car you are currently renting is legal since you have authorized possession of the vehicle. You should not permanently attach trackers (like magnetic devices under the chassis) as this may violate the rental agreement's terms about modifying the vehicle. A portable tracker placed inside the cabin is the appropriate approach for personal safety or trip documentation.
What happens if you take a rental car to Mexico or Canada?
Most standard US rental agreements prohibit taking vehicles into Mexico or Canada without specific authorization. GPS tracking will detect border crossings. If you need to travel internationally, contact the rental company before your trip — most companies offer international rental agreements for an additional fee that provides proper coverage and removes geographic restrictions. Crossing borders without authorization can result in significant fees and potential voiding of your rental insurance coverage.
Can you block a rental car's GPS tracker?
GPS jamming devices are illegal under FCC regulations in the United States and can result in federal fines up to $100,000. Additionally, disabling a rental car's GPS system almost certainly violates the rental agreement, can void your insurance coverage, and increases your personal liability if the vehicle is stolen. It is strongly advised never to attempt to block or disable rental car GPS tracking.
