This week's traffic tip is in regards to the Texas Transportation Code 547.616, Radar Interference Devices.

Sec. 547.616. Radar interference devices; offense.

(a) In this section, "radar interference device" means a device, a mechanism, an instrument or equipment that is designed, manufactured, used or intended to be used to interfere with, scramble, disrupt or otherwise cause to malfunction a radar or laser device used to measure the speed of a motor vehicle by a law enforcement agency of this state or a political subdivision of this state, including a "radar jamming device," "jammer," "scrambler" or "diffuser." The term does not include a ham radio, band radio or similar electronic device.

(b) A person, other than a law enforcement officer in the discharge of the officer's official duties, may not use, attempt to use, install, operate or attempt to operate a radar interference device in a motor vehicle operated by the person.

(c) A person may not purchase, sell or offer for sale a radar interference device to be used in a manner described by Subsection (b).

(d) A person who violates this section commits an offense. An offense under this subsection is a Class C misdemeanor.

Why this specific code and how does it relate to driving in Victoria?

A Victoria Police Department officer recently pulled over a car after estimating the speed to be higher than the posted limit. The officer was going to verify the speed using his radar, however, he was unable to obtain a valid speed reading on the vehicle for unknown reasons. A traffic stop was made on the vehicle and it was discovered that the vehicle had a radar interference device mounted in the front grill. The driver claimed that the device was installed at the factory. After contacting the factory, which is a very reputable auto manufacturer, it was discovered that the device was not installed at the factory. So, if you have a radar interference device on your vehicle, you can be cited for violation of state law and the device would be seized.
