Police Start Using New Radar Guns That Detect More Than Just Speed


You have probably seen police officers point a radar gun at passing cars. Those tools can be used to detect if a car is speeding by clocking a vehicle’s speed. But you probably didn’t know that those radar guns can also be used to see if a person is texting and driving! Distracted driving is a big problem. It is illegal in many states to text and drive, but people still do it.

A Virginia-based company developed the guns. They work by detecting radio frequencies – these frequencies are emitted from a cell phone. There is a different frequency the phone emits when a text message is being sent. When the radar gun detects the text message frequency, they know someone in the vehicle is texting while driving.
