Radar detectors are devices that help drivers detect police radar and avoid speeding tickets. Many drivers use them to save money and avoid fines. However, radar detectors are not legal everywhere. In some states, using them can lead to fines, penalties, or even confiscation. This guide explains where radar detectors are illegal, legal, and has answers to common questions.
What Is a Radar Detector?
A radar detector is an electronic device that senses radar signals used by police to measure vehicle speed. When the device detects radar, it alerts the driver with a sound or light. This allows the driver to slow down before getting a ticket.
Radar detectors are popular among long-distance drivers and people who drive on highways. However, not all states allow their use, and some have strict laws.
