Key Points:
- Laser jammers, devices that interfere with police laser speed guns using infrared signals, are used by some drivers to avoid speeding tickets but are illegal in 12 states and Washington, D.C. as of early 2025.
- Radar detectors, which alert drivers to radar gun signals rather than interfering with them, are only banned in Virginia and Washington, D.C., and cannot be used on military bases or in commercial vehicles over 10,000 pounds.
- Some drivers prefer non-intrusive methods like the Waze app’s police sighting feature, which alerts users to police presence based on community reports, helping them slow down without tampering with enforcement equipment.
- Google Maps offers speed limit reminders and a speedometer feature accessible via Android Auto that notifies drivers when they are exceeding speed limits, providing a legal and free alternative to avoid tickets.
- These navigation apps provide helpful, cost-free tools to promote safer driving and reduce speeding violations without relying on potentially illegal or controversial devices.
