The Whistler Z-19R Bilingual Laser Radar Detector is an excellent value. This high-performance, feature-packed detector offers not only the verbal alerts but also offers a full text display. You can choose either English or Spanish for both the voice alerts and for the text readout. Also included is Whistler's FDSR (Field Disturbance Sensor Rejection), the most recent advancement to combat false alerts caused by new vehicles equipped with Frequency-Modulated Continuous Wave (FMCW) K band blind spot and collision avoidance devices. And if you're wondering if you can use the Z-19R in your state, read on. Laser detectors are completely legal in every state when used in automobiles or light trucks (under 10,000 lbs.). Similarly, when used in automobiles or light trucks, radar detectors are legal in almost every state. Exceptions are Virginia and Washington DC, which have local regulations restricting the use of radar receivers in any vehicle. Concerning trucks over 10,000 lbs., the Federal Highway Administration (FHwA) issued a regulation, effective January 19, 1994, which prohibits nationally radar and laser detector use in these types of vehicles. Be safe on the road with Whistler!
