GPS tracking of employees during work hours is legal in all 50 U.S. states. There is no federal law that prohibits it. But "legal" doesn't mean "no requirements" — several states impose disclosure obligations, data retention limits, and in some cases specific consent procedures. Understanding the rules in your state before you start tracking is the difference between a smooth rollout and a legal exposure you didn't see coming.

The federal picture: no prohibiting law
At the federal level, there is no law that specifically prohibits or regulates GPS tracking of employees during work hours. The Electronic Communications Privacy Act (ECPA) regulates interception of electronic communications but does not apply to GPS location data in vehicles or on company-issued devices. The National Labor Relations Act is relevant if employees are organized — employers generally cannot surveil employees for the purpose of chilling union activity — but tracking job site locations and hours is not surveillance of that kind.
States with specific GPS or location tracking rules
California
California has the strictest privacy framework in the U.S. Under the California Consumer Privacy Act (CCPA) and California Privacy Rights Act (CPRA), employees have rights regarding how their personal information (including location data) is collected, used, and retained. Employers must provide employees with a notice at collection that describes the categories of personal information being collected and the purposes for which it will be used. This notice must be provided before or at the time of collection. In plain terms: you must tell California employees you're tracking them, what data you're keeping, and what you're doing with it before you start.
Illinois
Illinois does not have a GPS-specific statute, but two laws are relevant. The Illinois Employee Location Privacy Act (755 ILCS 20/1) restricts tracking employees' personal vehicles without consent — though this applies to personal vehicles, not company vehicles. For company devices and vehicles, written disclosure is the standard practice. The Biometric Information Privacy Act (BIPA) is not GPS-specific but creates a culture of elevated privacy expectations; field service companies in Illinois should have explicit GPS acknowledgment in their offer letters or handbooks.
New York
New York Labor Law Section 203-e prohibits employers from tracking employees' personal devices without their consent. This means if you ask technicians to use their personal phones for GPS tracking, you need explicit written consent. On company-issued devices, the requirement is disclosure — employees must be informed that the device may be monitored.
Texas
Texas has no state law specifically regulating employer GPS tracking of employees during work hours. Federal rules apply. Best practice is still written disclosure — if an employee believes they weren't told about tracking, it can create friction even if it's technically legal.
Other notable states
- →Connecticut: Employers must notify employees of any electronic monitoring, including GPS, before it begins.
- →Delaware: Similar to Connecticut — written policy notice is required.
- →Florida: No state law on employer GPS tracking. Federal law applies.
- →Washington: No GPS-specific statute, but the Washington Privacy Act creates broad data protection obligations.
- →Colorado: No GPS-specific statute, but Colorado's Privacy Act (CPA) requires disclosure for collection of sensitive personal data.
The three rules that apply everywhere
Even in states without specific GPS laws, three principles apply universally and are simply good employer practice:
- →Disclose before you track. Put it in writing — offer letter, employee handbook, onboarding form. Get a signed acknowledgment. This protects you even in states with no explicit requirement because it eliminates the "I didn't know" argument in any dispute.
- →Track only during work hours. Tracking employees on personal time — evenings, weekends, days off — dramatically increases your legal exposure and destroys employee trust. A proper system should make it technically impossible to track outside shift hours, not just policy-based.
- →Retain data only as long as needed. Data you don't have can't be subpoenaed, leaked, or misused. Set an automatic retention policy — 12 months for GPS location data is a reasonable industry standard.
Personal devices vs. company devices
The legal analysis is cleaner for company-issued devices — the employer owns the device and the employee's expectation of privacy is lower. For personal (BYOD) devices, several states require explicit consent. The practical recommendation for most field service companies: issue devices to field technicians, or use a dedicated work app that clearly scopes its tracking to work hours only. Employees should be able to verify what's being tracked and when.
What to put in your employee GPS policy
- →A clear statement that GPS tracking is used during work hours
- →The specific data collected (location coordinates, timestamps, speed)
- →How the data is used (timecard generation, crew visibility for dispatch)
- →Who can see the data (managers, HR, payroll)
- →How long the data is retained before deletion
- →Whether employees can view their own data (yes is always better)
- →The process for disputing an entry
- →That tracking stops at the end of shift and does not operate on personal time
Bottom line
GPS tracking of field employees during work hours is legal across the U.S. with proper disclosure. Write a policy, get signed acknowledgments, track only during shift hours, and delete data you no longer need.
