If it's one thing the Lone Star State has its wide-open highways that stretch as far as the eye can see. So, it's no wonder that speed limits can sometimes feel more like suggestions if you're an eager driver. For as long as I can remember, radar detectors (or fuzz-busters) have been used by those seeking an extra layer of protection against sneaky law enforcement and speed traps.

What Does Texas Law Say in 2023?

Radar detectors are perfectly legal in Texas however there are conditions. While it's legal to have one in private vehicles, it is illegal to have a radar detector or a laser speed detector in a commercial vehicle weighing over 10,000 pounds such as an 18-wheeler.

Additionally, radar detectors are prohibited in any vehicle that's on a military base or installation.

Radar vs. Lidar Detectors: What's the Difference?

In years past police used radar scanners to check the speed of drivers. Radar scanners beam a radio wave that bounces back off the car to the scanner. This measures the vehicle's speed. Nowadays, however, police departments almost always use lidar scanners instead. These types of scanners use a beam of infrared light to track the speed of a vehicle.

Lidar detectors do exist and are absolutely legal to have in private vehicles. The only downside is that they can be pricey.

So, at least for now, these detectors remain legal for use in Texas providing drivers with an additional tool of awareness on the road. Stay vigilant, stay legal, and stay safe on your journeys across the Lone Star State.

The law is the law in Texas. But some of these ordinances will leave you scratching your head. Look below for some silly state laws that are actually still on the books.
