Lets face it, most of us have received a speeding ticket at some point in our lifetime. As a result, radar detectors have become commonplace for drivers that want to take preventative measures to avoid receiving a ticket. Such preventative measures bring up an important question: are radar detectors illegal? Can I get a ticket for using a radar detector?
In Texas, using a radar detector in a passenger vehicle is legal with certain restrictions.
Under federal law, however, using a radar detector in any commercial vehicle that has a weight of 10,000 pounds or more is strictly prohibited. Commercial drivers are treated as professional drivers, and thus, different laws apply to them. 49 C.F.R. § 392.71(a).
Is it Legal to Mount a Radar Detector on My Windshield?
Although radar detectors are legal in Texas, a person may still be ticketed if they have mounted their radar detector on their windshield, side, or rear window, and that placement obstructs or reduces the operator’s clear view. Whether or not the placement obstructs an operator’s view is up to the officer’s discretion. As such, to avoid the hassle all together, it is best not to mount your radar detector on your windshield.
Radar Detectors on Military Bases
According to the Department of Defense instructions, persons are strictly prohibited from using radar or laser detection devices on military bases. Department of Defense, DoD Instruction 6055.04, DOD TRAFFIC SAFETY PROGRAM pg. 12 (2013).
What is the Difference Between a Radar Detector and a Radar Jammer?
Over the years, many devices have been created to help prevent speeders from being ticketed. The most common device is the radar detector, which is designed to locate radar signals out of the air. However, radar detectors have become less effective due to advances in technology and policing. This has generated the need for LIDAR/RADAR jamming devices. Unlike the traditional radar detector, a jamming device transmits a radio frequency signal that blocks or otherwise interferes with the operation of police LIDAR/RADAR by overloading its receiver with false information. Jamming devices can cause significant damage to police equipment. Moreover, such devices not only prevent police from detecting the speed of the vehicle with the device, but also the vehicles in the surrounding area.
Accordingly, in 2011, Texas passed HB 1116 to prohibit a person from using, attempting to use, installing, operating, or attempting to operate a radar interference device in a motor vehicle operated by the person. A person who commits an offense under this section may be charged with a class C misdemeanor. Tex. Transp. Code § 547.616. A Class C misdemeanor is punishable by a fine not to exceed $500.
While many people believe radar detectors promote unsafe driving, advocates refute this contention by explaining that radar detectors alert drivers to their speed and remind them to drive the speed limit, and thus, safer.
In conclusion, spending money on a radar detector may help you dodge a speeding ticket and possibly even drive safer, but there are other laws that may be implicated when using such devices.
