If you see a policeman using a radar gun, is it legal to flash your lights to oncoming traffic to altert them?

Its not legal in any state, its done on 1/4 mile race cars for show only, on rocket cars , or hydrogen rocket cars,\nthe use a stainless steel ring fitted to the rear or the exh portion of the vehicle, with small holes around it, fitted with a pressure hose to a charged tank of gasoline and and igniters switch at the ring, called after burnner\nas the exh comes out the switch or valve is open they actvate the ignighter and with the exh coming out, it will throw a flame, this more complacated than you think, with all the saftey stuff i am skipping through. if its not for a show at a race track, dont even try it

UNFORTUNATELY IT WORKS, IS DIRECTLY CONNECTED WITH A SPEED SENSOR CONNECT TO THE OFFICER'S VEHICLE.  IT WORKS APPROACHING OR ON-COMING.  ANTENNA'S ON VEHICLES ARE DIFFERENT BUT DOWN HERE WE USE A ANTENNA WHICH APPEARS TO BE A SPOTLIGHT HOOKED OVER THE TOP OF THE WINDOW GLASS.  IT MAY BE AIMED UP OR DOWN THE ROAD.\n\nWORKS AS LONG AS THE VEHICLE IS IN SIGHT!\n\nDRIVE CAREFUL HEAR !

I don't know about in NY, but it can happen in GA;  cop wrote ticket for failure to yield right of way; guy even admitted he ran the red light light; witnesses all agreed;  judge let him go b/c officer should have written "failure to yield right of way while making a left hand turn"!!

Police are trained very heavy in multi-tasking so yes the can talk on the phone and chase people at high speeds and talk on the radio while running after someone and send a description of the suspect via phone or radio. So give them a bit of a break. Tough job. Before you criticize try it first. Bet you will be all over them thanking them when YOU need them. \nBut yes you Can report them if they are relay doing something wrong. just get the car number. But as far as speeding for them...How do you know they are not on a mission....they do have to obey the laws but if they are on a call that needs a silent alarm..do you know...NO. And buy the way Fire trucks and Ambulances have to adhere to the rules too..even with the lights and sirens on!

Ha\n\nInteresting speculation \n\n1. The light will not change color no matter how fast you go. Only in your perception it will, so unless the law enforcement is traveling within your frame of reference you would be found guilty anyway.\n2. True, if you are moving towards the light its frequency will increase towards the blue and will appear green to you, but the acceleration would kill you.  \n3. If you could travel with speed of light why would you care about traffic lights?\n\nGood question anyway.

A officier can not legally stop you outside of his jurisdiction.\n\nIf he did not turn on his lights and siren before he crossed his state line, then it was not a legal stop.\n\nA attorney can eat this up, even including possible illegal stop and detention by the police officer

How do you know you were doing 33 mph? The cameras have the buffer already set in them .. so if you were flashed, there is a high possibility that you were doing more than the buffer includes and therefore you may well get a ticket and subsequent points... sorry for the bad news.

It is illegal in the state of Washington to drive through a red light.  The yellow light is given to warn you the light will change soon.  It is the drivers responsibility to make sure they are through the intersection before the light turn red.  However, high traffic volumes often make it nearly impossible to turn left.  Sometimes people are forced to wait until traffic clears after the light turns red.  \n\nTo answer your question:  It is illegal, but everyone does it.  It happens so offten it is hard for the police to enforce.

Almost every state has laws that authorize law enforcement to exceed the speed limit during the course of their duties, as most receive special training to drive at faster speeds. The reasoning for this is that there are times when you don't want to draw attention to yourself as you attempting to get somewhere thereby alerting the bad guys.

Well, the question about blue lights tells me you're not in California.  If you had said what state you are in, someone might have been able to give you a better answer (maybe your state requires law enforcement to use their emergency lights to pull you over....but I doubt it very much).\n\nThat said, not using his lights on you was a very clever tactic that experienced police officers use.  Without the lights, there is probably no issue as to detention (meaning he didn't even need a reason to stop you, because you stopped yourself and he just walked up and began talking to you).  Police officers, just like everyone else in the country, have the right to walk up to someone and just start talking to them - and if the person stands there and engages in conversation, it's all good and anything that comes from it is just as constitutionally sound as if the officer had probable cause to make the stop in the first place.  \n\nHowever, if the officer pulled in behind you and blocked your ability to leave - even if you didn't try or want to - then it very likely will be considered a detention by the courts, and will require the appropriate constitutional factors to justify the detention.  You said the officer arranged for another cop car to block your way, so that would likely be considered a detention by the courts.  However, the officer is claiming you were speeding, so assuming he can prove that to the court's satisfaction, he could have called in a hundred cars to block you in and it wouldn't matter...blue lights or no.

Dear Tony Cologne,\n When you say a red car appearing to move faster, do you mean to the human eye or to the device that the cops use. I think you may have some confusion that is evident in popular lore about the Doppler shift. \nHowever, you might have a point about the cops coming to a complete stop and then catching up again within a quarter mile. At 37 mph a quarter mile is 24 seconds. That means the whole time they are stopping it is adding to your lead as well as the whole time they are accelerating to catch up. Then once they surpass your velocity they have to exceed it enough to catch up within what is left of the 24 seconds they started with. Plus, nobody pulls over right away the instant the lights start flashing. If you had a savvy lawyer you might have a case, plus the judges know these cops usually embellish the truth. Who cares, its a traffic ticket, might as well fight it and have some fun. Its not like you'll get the death penalty if you lose.

Not unless you have radar absorbing paint which the government would love to have too.  I was picked up on a 10 speed bike trailing all kinds of foil to mask me but I was still picked up and clocked by police radar gun.  If you find a way post it.  I want to know that trick.  You can overload them with powerful transmitters, the radar reads false speed like 200mph which is not reliable for court,especially when I drive a 1972 VW bug, but they are illegal.

Yes if the officer is trained in using it. No if it's for photo radar.

Most often, especially for low speed applications, it is a matrix of carbon fibers in a foam substrate.  At higher speeds, carbon fiber composites can be used, but radar waves can even be reflected from insulating materials (due to the change in dielectric constant between air and the material).  Many of these things reflect very poorly, though.  Coating the front of your car would not likely help with the local police radar -- however.

They can now and here in Florida it is legal for a person to shoot if they feel that they are in danger for their life. And you know what, if someone bashed my door down I'd shoot first and ask questions later. I think this may be very bad for all the police trying to do their jobs. What in Gods' name were they thinking? Some idiot right wingers may think this is OK but heaven help the cops.

Yes, traffic cops use them to collect data on the average speeds of traffic at different times.  There's one on my way in from work on the midnight shift the speed limit is 30 and I usually try to go as fast as possible, 60-70mph just for fun.  But then again I am driving a squad car.
