3.2 Vehicle Tracking Devices & Consent

Vehicle Tracking Devices & Consent

Tennessee does not grant private investigators a professional exception to vehicle-tracking law. Apply T.C.A. § 39-13-606 before touching a client’s proposed device.

General prohibition

It is an offense knowingly to install, conceal, or otherwise place an electronic tracking device in or on a motor vehicle, without the consent of all owners, for the purpose of monitoring or following an occupant or occupants.

Break the rule into elements:

• a knowing placement;
• an electronic tracking device;
• in or on a motor vehicle;
• a monitoring/following purpose; and
• missing consent from every owner.

An “owner” includes a person who purchased the vehicle using a loan. A lender’s security interest is not the same thing as owner consent for a private domestic investigation.

The title and registration records are a starting point for ownership analysis. A client’s statement that “we paid for it together,” “I make the payments,” or “it is marital property” does not establish that the client can satisfy the criminal statute. Obtain reliable ownership documentation and written consent from every owner before considering placement.

Leased vehicles

A person who leases a motor vehicle may not knowingly place a device in or on it without the lessee’s consent. This prevents a lessor from treating title ownership as unrestricted authority to monitor the lessee.

An investigator should identify whether the arrangement is a statutory lease, rental, company assignment, financed purchase, or informal permission. Do not assume that the person holding keys or paying an invoice is the legally relevant consenting person.

Express statutory exceptions

The section identifies these circumstances:

1. Law enforcement: placement by or at the direction of a law-enforcement officer in furtherance of a criminal investigation, carried out consistently with state and federal law.
2. Parent or guardian: placement by or at the direction of a parent or legal guardian who owns or leases the vehicle, used solely to monitor that person’s minor child while the child is an occupant.
3. Stolen goods or vehicle: placement to track stolen goods being transported or to track the vehicle if it is stolen.
4. Manufacturer system: the section does not apply to a tracking system installed by the motor-vehicle manufacturer.

Read the parent exception precisely. It requires the parent or guardian to own or lease the vehicle, the person monitored to be that parent’s or guardian’s minor child, the child to be an occupant, and the purpose to be solely monitoring that child. The statute does not use the former draft’s “unmarried minor daughter” formula.

The law-enforcement exception does not let a private investigator claim to be acting “like” law enforcement. Actual legal direction and compliance are required.

The statute does not create general exceptions for:

• a private investigator working for a paying client;
• a spouse who lacks the necessary ownership status;
• an employer’s entire fleet without an ownership/lease and consent analysis;
• a lienholder or repossession agent merely because money is owed; or
• a device the client installs after the investigator supplies instructions.

Aiding, arranging, or procuring unlawful conduct can create risk even when the investigator never physically attaches the device.

Class A misdemeanor and licensing exposure

A violation of § 39-13-606 is a Class A misdemeanor. The criminal classification is the direct statutory answer. A license complaint may also follow, but § 62-26-217 gives the Commissioner disciplinary authority through a separate process. Do not claim that conviction automatically causes permanent revocation unless current law expressly makes that result mandatory.

Telematics and account access

A factory-installed system is outside this specific placement section, but that does not authorize an investigator to enter another person’s connected-car account, guess credentials, use a stolen session, or obtain provider data through pretext. The method used to retrieve location data can implicate computer-access, stored-communications, contract, and privacy law.

Likewise, sharing a phone’s location or adding an account-level tracker differs factually from placing a device on a vehicle. Apply the statute that matches the device and access method; do not treat § 39-13-606 as the only relevant law.

Intake protocol

For any tracking request:

1. identify the exact vehicle by VIN and plate;
2. obtain current title/lease documentation;
3. identify every owner and any lessee;
4. document each required consent;
5. identify the person to be monitored and the purpose;
6. test whether a precise statutory exception applies;
7. reject any request based on concealment from a required owner or lessee; and
8. consider whether ordinary visual surveillance can meet the lawful objective.

Domestic scenario

A client asks to track an SUV titled only to the client’s spouse. The client says the vehicle was purchased during the marriage. The investigator must refuse absent lawful authority: the client has not shown consent from the titled owner, and marriage is not a private-investigator exception.

Parent scenario

A parent owns the vehicle and places a device solely to monitor the parent’s minor child while the child occupies it. That fits the text if the other conditions are satisfied. It does not authorize monitoring another adult who later uses the same car for an unrelated purpose.

Exam method

Identify owners, lessee, installer, target occupant, and purpose. Then compare the facts with the four statutory exceptions. If the answer relies only on client permission, marital status, professional licensure, debt, or a broad business purpose, it is likely wrong.
