Frequently Asked Questions About Radar Detectors

Q: Are radar detectors legal?

A: Yes, Radar Detectors are legal across the country except in Virginia and Washington D.C, or in commercial truck over 10,000 pounds. Check out our selection of Radar Detectors that are Radar Detector Detector Immune, if you’re worried about driving in one of these states or simply want to stay below the radar.

Q: Do radar detectors work?

A: Yes, and if used properly their effectiveness at detecting radar can help save you from getting your next ticket. All radar detectors work on the principal of advanced detection allowing you time to adjust your driving before ever being seen. With some minor tweaks to your driving habits you too can be ticket free. See our Radar Detector School to learn more about effective implementation of a radar detector.

Q: Why didn’t my radar detector go off when I passed a cop?

A: While a radar detector is a great tool for detecting radar, it can’t detect what’s not there. If a police officer doesn’t have a radar gun on or in their vehicle, the radar detector will not alert. Note that a very high percentage of   of Police cars across the United States do not have radars installed in their vehicles, and that number will only grow with the use of LIDAR and other methods of speed detection.

Q: Why is my radar detector going off when there’s no police around?

A: Radar detectors detect three primary bands of radar X, K, and Ka and while a police radar gun uses all of them, all of them are not exclusively used by police. Other sources include automatic door openers at stores, other radar detectors, Highway Traffic Monitoring (TMF) and most annoyingly the NEW collision avoidance/Blind Spot Monitoring systems (BMS). Since the FCC heavily regulates the use of Ka to almost just law enforcement officials, most fasles you will receive come from X and K band. If you find that your detector is alerting more times to these falses than actual threats, look into getting anyone of our products with GPS lockouts, and or TMF/ BSM filters. I guarantee a good filter will be one of the best investments you can make when purchasing a radar detector.

Q: Why don’t you sell radar jammers?

A: Radar Jammers are a Felonious Offence in the United States with up to a $50,000 fine and 5-years in jail.

A.b: Up until 2006 there was a hand full of companies manufacturing “Radar Jammers”, most of which worked intermittingly or were just marketing gimmicks. At that time the principal of jamming relied heavily on the source of the radar signal coming from an analog based operating system. Although sometimes effective these systems were prone to malfunctions and often times only jammed the radar to a range greater than 500ft+ at which point the officer could then clock your speed. Around 2006 the adoption of newer Digital based radar systems were brought into use and the principal of jamming radar became much more difficult, requiring expensive bulky equipment that was even less effective at jamming radar. Now most radar systems in use today are digital, and no company has stepped up to provide an effective solution since. It is for this reason Rebel Radar will not sell radar jammers.

Q: What does X, K, and Ka band mean?

A: X, K, and Ka are the three different frequencies that police radar guns operate on in the US. Knowing which band is alerting can help you as the user determine the likely hood of a real threat. X band is the oldest and least common, operating around 10.5 GHz, and only still used in a few places around the country such as OH, NJ, and OR. K band is slightly newer and operates at 24 GHz, and is used all over the country. Unfortunately, K band is the primary band of false alerts from Highway Traffic Monitoring (TMF) and NEW collision avoidance/Blind Spot Monitoring systems (BMS). Ka is the newest and most common band you’ll find used in police cars today at 33.8, 34.7, & 35.5 GHz. Ka band is a very popular frequency for law enforcement and there for should always be taken seriously. To find out what is used in your area, click here.

Q: Does police radar work while they’re driving?

A: Yes. Radar guns have many different features allowing police to gather your speed while their stopped or driving referred to as stationary or moving mode. A good rule of thumb is “if you can see them, they can see you and gather your speed”.

Q: Can my speed be read when I’m behind a police car?

A: Yes.  Police radar is directional and when aimed can detect your speed from any side.

Q: What are Radar Detector Detectors?

A: A Radar Detector Detector (RDD) is just what it sounds like, a device that detects the presents of a Radar Detector while in use. The device works by detecting the “leakage” most Radar Detectors give off up to a range of ~ ½ a mile. Currently, only a handful of Radar Detectors are RDD immune giving off no trace of their presents (Escorts Redline & 9500ci, Beltronics Magnum & STIR+, and the Stinger VIP). Although used all around the US in small doses while looking for commercial truck drivers (<10,000lbs) the vast majority are found in Virginia and Washington D.C. where Radar Detector use is prohibited.

Q: Which radar detector is best for me?

A: That depends on your own personal needs, preferences, and where you drive. Take our Radar Detector Test to find out which is the best for you.

Q: Do I really need a 13 mile detection range from my detector, can’t I just get away using a cheaper one?

A: When Escort got a 13 mile detection from the Redline in 2013 it was under ideal conditions, conditions which the avg. detector user will rarely ever see! A radar detector’s performance can easily be impaired by environmental conditions such as weather, hills, other vehicles, and even invisible electro-magnetic interference which can reduce range to just feet of detection.

Additionally, law enforcement aware of the use of radar detectors deploy tactics against them in hopes of reducing their effectiveness. By turning off and on their radar, referred to as Instant On (I/O), they’re able to catch most entry level radar detector’s users. Lying in wait unit you’re just within range they’ll blast you with a short burst of radar only long enough to gather your speed then turn the radar back off for the next unsuspecting customer to come along. Difficult to defeat this is tactic is only overcome with raw detection range and the use of “Rabbits” (other I/O bait in front of you).

Combine all these real world interferences with tactics used by law enforcement to defeat radar detectors, you’d be wise to get the highest performing unit possible.

Q: Where’s the best place to mount my radar detector?

A: A radar detectors best performance is as high as possible, while still maintaining a clear “view” of the road ahead and behind. “View” being clear of obstructions from window tint, other devices and objects. The detector must be level from front to back, and mounted horizontal for use in the US. Furth more, keeping other electronic devices (GPS, Dash Cams, ect.) as far away as possible to reduce possible electro-magnetic interference is advised.

Q: What do you recommend to someone who’s starting out?

A: Where you live and how you drive will determine what kind of protection you need. Police use a number of different tactics to determine your speed and there for you may just need one or many tools for complete protection. Check to see what’s used in your local area HERE then follow our guild below to the equipment you need to protect against detection.

Frequently Asked Questions About Laser Jammers

Q: Are laser jammers legal?

A: Legal in 40 out of the 50 states odds are Yes, if by chance however you live in California, Colorado, Illinois, Minnesota, Oklahoma, South Carolina, Tennessee, Texas, Utah, Virginia, & Washington D.C. the answer is no.

Typical penaltys for getting caught with a jammer in prohibited states are generally along the lines of a Class C Misdemeanor Non-Moving Violation incurring no points or insurance hikes (“Fix-it-ticket”). In many cases receiving a speeding ticket would do more harm financially and to your driving record than would the ticket for using a laser jammer in the first place. You should still check local laws first for yourself before making any decisions in the matter. This is not legal advice.

Q: Do I still need to purchase a Laser Jammer for laser protection if I already have a Radar & Laser Detector?

A: Yes. LIDAR or LASER guns work by emitting a beam of laser within line-of-sight reflecting off the target and reporting back to the gun with a speed within ¼ of a second. From the perspective of a speeder the mere detection of laser would be pointless if the only reaction time you have to adjust your speed is less than that of a ¼ second. For this reason Laser Jammers are a necessity for true laser protection momentarily blocking the LIDAR or LASER guns ability to detect your speed giving you vital time to adjust. Once your speed has been adjusted; turn off the laser jammer allowing the officer to detect your speed at or below the speed limit leaving no one the wiser to presence of the device.

Q: Do Laser Jammers work?

A: Yes. All current laser guns in use within the US are Jammable, even the Dragoneye.

Q: Would I still need to purchase a radar detector if I buy a Laser Jammer?

A: Only if you need protection from radar. Laser Jammers DO NOT detect radar, and radar detectors DO NOT jam laser. If you want protection from both radar and laser you will need both a radar detector and laser jammer, we do however sell integrated systems with both.
