Yes. The glass does not affect the radar.
Yes, barring interfering factors.Another View: I'm not certain that the customary hand-held models of police radar can be accurate at that range, and concede that they could be, depending on the equipment, but I DO know that speed checkiing lasers ARE accurate at that distance.
Very accurate, it measures speed and doesn't care if the vehicle is traveling up or down, toward or away from the radar gun.

No. With police officers in motion, it would appear that cars would be going slower. Say that a car is going 50 MPH, and you are going 45 MPH. Eventually the vehicle wil be ahead of you. Now say you are a police officer with radar. If you test this car, it will appear (on radar) that the 50 MPH car is only going 5 MPH, thus to get the accurate speed, you must be going 0 MPH.Disagree. The original police radar required a stationary unit. Radar is use for the past 30 years is capabable of adding or deducting the speed of the police car from the observed speed. It does not require that the police car be in one fixed spot.Added: The second cotributor is correct. I seriously doubt that any of the old radar units are still in operation much less certifiable as accurate. ALSO: the term "radar" is a commonly used by the the public to describe ALL police speed-clocking devices. Any of these can be calibrated to be used while the vehicles are in motion.
There is a device called a radar detector, but it will only detect a radar signal, not police in general.
The answer is "yes." Traffic radar monitors both the speed of the vehicle in which is it mounted and the speed of "target" vehicles coming toward or moving away from it. On the radar display, the officer sees two speeds: "patrol" (the speed of his vehicle) and "target" (the speed of the vehicle the radar is tracking). the target speed measurement is equally accurate, whether the patrol vehicle is moving or not.
It is not a requirement to show RADAR readings in Illinois.
i don't the answer
Having a radar detector will alert you when a Police Car with its speed radar is near. The Radar Detectors will produce an audible signal alerting you of this, and will do so far in advance of when you are able to see the Police Car.
The answer, both technologically and legally, is "No". Most modern in-car Police radar systems can work while the vehicle is moving.
At any time.
