The secret they don't want you to know: When tra c Radar shows a Speed reading, it does not indicate which vehicle is being clocked. The Truth about Speed Enforcement How Radar and laser guns measure your Speed Why they make mistakes How they are used unfairly How to protect yourself Radar How tra c Radar works How far away can Radar clock you? If all vehicles were identical, the strongest re ection would be from the Tra c Radar units send out a wide Radar range depends on the size and closest car. But di erent vehicles re ect Radar beam that's similar to an invisible shape of the vehicle. Radar can track a di erent amounts of the Radar signal. spotlight. The Radar beam widens as it large truck from over one mile away, even travels, and measures several hundred too far to be seen by eye. But some sports Radar 's most common error: feet wide at a distance of one-half mile. So cars bounce back such a weak signal that mistaken identity a tra c Radar unit simultaneously sees they must be within 500 feet to be clocked.

How Radar makes mistakes More than a dozen technical errors for tra c Radar have also Although tra c Radar receives been documented, but mistaken identity re ected signals from all cars within (technically called a target identi cation range, it has no way to display all the error ) is by far the most common.

As with any complex electronic laser light that is so narrow and precise Because of the narrow beams, laser device, there can be technical it must be aimed with an optical sight, units are hand-held, and can only be malfunctions and miscalibrations. It's like those used by sharpshooters.

Radar and laser : Fair or unfair? Why Radar and laser are used: The fact is, Radar and laser Speed of Radar and laser clocked tickets has it's not always about safety measurement are used to make it easier balanced more than one town's budget.

Many times they are set up to booking almost $4 million in revenue. and out of tra c) police are rightfully monitor the Speed of every vehicle that enforcing tra c safety laws. But more passes. The high cost to the motorist often than not, tra c Radar is not about safety. It's about revenue. And Enforcement is often highly The cost of a single ticket can add selective, with almost all vehicles up to thousands of dollars. The ne exceeding an often unreasonably-low itself can range from $200 to $400 or posted Speed limit, but only a few more, with insurance increases that vehicles stopped. can add as much as $1,000 to $1,500 in additional premiums.

One town in West Virginia with a population of only 3,200 issued more than 18,000 tickets in a single year, booking almost $4 million in revenue How to protect yourself with a Radar and laser detector Fortunately, there is help. Modern How detectors provide beam to hit your car and bounce back. Radar and laser detectors are e ective advanced warning But your Radar detector can pick up tools to defend against unfair tickets. re ections from the microwave beam Can a Radar detector nd police Radar well before it hits you directly. You can Today's Radar detectors are high- before it nds you? The answer is yes. see it before it sees you.
7 Performance, high-technology devices. Suppose you're heading right into the In the last decade, advances in beam of a Radar trap. To measure your Instant-on Radar and laser microcircuitry, signal processing and Speed , the Radar beam has to hit you chip design have led to the design of and be re ected back to the Radar unit, One technique can be hard to defend premium Radar detectors which virtually returning with enough strength to be against, the so-called Instant- on. Here, eliminate false alarms and provide sensed by the calculating circuitry. the Radar or laser unit is in a stand-by longer range warning of Radar and laser mode until a vehicle approaches. It is not with great accuracy. Your Radar detector, however, has a emitting a beam so your detector can't job that's considerably easier, since the nd it. Then, when you are within range, How a Radar detector works signal only has to travel one way to reach the operator switches the unit on and it you.

A Radar detector is simply a receiver Radar before it can detect you. tuned to detect the presence of the Radar A good Radar detector protects you and laser frequencies used by tra c Radar can't work around curves. by warning you when the operator zaps . monitors.

There has to be sensitive enough to pick up are three di erent Radar bands approved A Radar beam acts like the beam these brief, weak signals. And reliable by the FCC in use by tra c monitoring from a ashlight on a foggy night. The enough so you don't interpret them as units: X, K, and Ka band. person holding the ashlight can't see random false alarms and ignore them. you until the beam makes a direct hit. But you can see the beam through the Photo Radar X-band K-band fog-as it re ects o moisture and dust in the air long before it falls on you.
9 Approximately 200 short-range stationary photo Radar units are in use In much the same way, police Radar around the country. Fortunately, a good Ka-band laser can't see you over a hill or around a Radar detector can provide advanced corner, because there's no way for the warning of these new systems. Types of Radar and laser detectors Conventional, Windshield-mounted Cordless, Windshield-mounted Custom-installed Most Radar detectors are portable, Cordless detectors are powered by A custom-installed Radar and laser and mount in seconds to your car's batteries instead of a car cord, and are detector is a multi-piece system that can windshield with a suction cup mount.
