This act makes it an offence to interfere with electronic communications or devices, which could extend to the unauthorised disabling or accessing of vehicle tracking systems.
2. In the United States
In the U.S., laws regarding vehicle tracking are intricate and vary considerably from state to state. However, generally, tracking someone’s car without their consent is illegal under federal and state privacy laws.
Federal Law
The Electronic Communications Privacy Act (ECPA) and the Computer Fraud and Abuse Act (CFAA) offer some protection against unauthorised tracking. These laws prohibit the interception of electronic communications and unauthorised access to computer systems.
State Laws
Many states have enacted specific laws that explicitly prohibit the installation of GPS trackers on someone’s vehicle without their consent. It is always advisable to consult your local regulations, as penalties for violations can be substantial.
3. In the European Union
The General Data Protection Regulation (GDPR) provides comprehensive data protection for individuals within the EU. Tracking a vehicle without the explicit consent of the owner or driver is a serious violation of GDPR.
Explicit Consent
Under GDPR, explicit, informed consent is mandatory for tracking activities. Individuals must be clearly informed about what data is being collected, how it will be used, and who will have access to it. This includes the use of tracking devices and apps.
Penalties
Violations of GDPR can result in significant fines, potentially reaching millions of Euros or a percentage of a company's global annual turnover. This underscores the importance of adhering strictly to these regulations.
How to Detect If Your Car Is Being Tracked
If you suspect that your vehicle is being tracked, there are several practical steps you can take to confirm your suspicions and address your concerns effectively.
1. Thorough Physical Inspection
Conduct a meticulous physical inspection of your vehicle, paying close attention to areas where a GPS tracker might be hidden. Remember that many trackers are small and designed to be inconspicuous.

Undercarriage and Bumpers
Check the entire undercarriage of your car, including the chassis, frame, and wheel wells, for any unfamiliar devices, wires, or magnetic attachments. These are common hiding spots for standalone GPS trackers, which often use magnets for attachment.
Interior Checks
Inspect the vehicle's interior thoroughly. Look under seats, behind panels, in the glove compartment, and near the dashboard. Pay attention to anything that looks out of place or has been recently tampered with.
