Well the uneducated here needs some help. I have a friend who got pulled the other day. Now they were going down the road and the cop was coming down the road in the other direction. The cop then pulls them and says they were doing 80 in a 55...I thought radar guns didn't work if the cop was moving...how does it not distort your speed if he's coming at you at 55mph? If the gun sends a signal out and he's coming in your direction wouldn't that make your speed faster than what you were doing? I have no idea here so I was wondering if any of y'all knew. Thanks! (and oh yeah, this isn't a cop bashing thread, I just want to know how this all works)

Well I know that more experienced cops can pull you over without radar. I am pretty sure the car has to be stationary to get a correct reading.

i don't know how he clocked you while moving, unless he subtracted his speed from what your friends speed was, cuz according to physics (If i still remember) if your both going 50 in opposing directions, it would clock you at 100 mph.

So he might be able to just do some math, but your friend will have to go to court, and there you could probably find out for sure, and unless cops are aloud to do that, your friend should go free.

Unless he got you on radar or was pacing you, he can only guess your speed.

See that's the thing I don't know, he was coming towards my friend on the highway and said he clocked them doing 80 in a 55...which means his car was probably moving at 55 or 60 also so I don't see how his radar could be accurate if his car is moving towards the car he is gunning.

i've seen them do it pretty often... thats just one of their strategies i guess

I had the same problem, with one of my friends and his Teg. We were going about 50 in a 45 and the cop pulled us over for going 75. Even though minivans were speeding past us. He also wrote him up for illegal stuff. But there are some radar guns that plug into the car and calculate your speed and their speed in some big equation. But he didnt have that radar gun. So my friend contested it and won. So first ask what the calibration and all the whoohoo was of the gun. BTW how fast were you going?

it's called the "Doppler Effect", some radar guns that are mounted to the car can calculate your speed by using the speed of the car that it's mounted in to calculate your speed. That's the simplified answer.

im a genius on this, dont worry. my sister had to do a couple of ridealongs with a statie for this class she was taking, and she said that he pulled over mad people like that. like thats the only way the radar works is if you are going towards the cop. if he is going the same way as you, he can only pace you. but if hes comin at you, or has a speed trap set up, he can accurately get ur speed.

I'd be pis-sed too, if I was pulled over.

$300 will get you a good detector/scrambler... Make shure the one you get works on laser and radar. Just make shure they are legal in your state. I can't remeber where to find them on the web. Ill post back if I find a site that sells em. I had one a while back and it always kept me safe. Don't ask me why I don't have it now...

Radar/Laser guns take the speed of the cop car into its calculation of your speed. Next time you get pulled over and know you were not speeding ask to see the speed sig on the gun. It should also have a time sig as to when the cop clocked you. If you were pulled over at 8:00pm and the gun says 5:15pm... Bye Bye ticket! If the gun has no time sig then it is an old obsolete model, bring this up in court. Also if the cop doesn't want to show you the sig, he has to. It is the only way he can prove that you were speeding so he must show you that evidence.
There are also tons of point with surrounding traffic and whatnot.

Tickets are easy to get out of... You just have to know the system!

Good Luck

Well as much this sucks balls, I got a ticket on Valentine's day! Whoo hoo! It was a great way to start off the night w/my gf. Well it was a simple infraction. I made a left turn into a parking structure. Now the cop (of course came out of no where) writes me up for making a U-turn in a Business District. I think I went over a double yellow but not sure. The parking guy saw this and told me that I could make left turns to get into the lot. He told me to go contest the ticket. If I were to do so, and plead NOT GUILTY, do I have to give reasons why? What can I say, would I have a good chance of getting off?
If they do find me guilty, is it to late to go to traffic school? And do you end up paying more than the initial fine?

....ANY HELP IS APPRECIATED! BRB240, you seem knowledgable, but i know u dont live in calif. Anyone in California let me not the deal. Thanks.

BTW: Deep down inside, I had a gut feeling that something might happen when I turned. Usually in Old Town Pasadena, I dont take chances AT ALL! And actually, it was my gf that told me to turn. Im ****ed. Help!! good night.

buy a valentine one, hardwire it to your fuse box. if they pull you over they will shine the flashlight on the windshield and check for suction cup marks or a cord in your lighter spot, valentine has a visor clip that you can just clip off and thow under your seat,

its illegal here in va to have them, but its not a very expensive ticket , if it goes down to it, sometimes they take the radar detector, so go buy a really cheap pos to have in in your glove box incase they do search, then you dont get your 400 dollar scanner taken, but with so much traffic around the area, its not likely they will be able to pick you out that your the car with the detector


good luck

I'm with Mr. Rogers. **** the Censorship thing. And **** the police.
You know thinking about it, all three of those things have sh*tloads of things in common. Like one big cluster Fu*k.
I heard it's all about the Valentine One though. World's better compared to almost all others.

P.S. Sorry I flipped this into a cop bashing bit. well. . . not really.
