Does hanging a CD from the mirror in your car really have an affect on radar guns? I heard this recently for the first time.
CD on rear view mirror?

Some guys are sooo dumb…
Since radar works on reflection from the whole car, it's hard to imagine how a reflective device that small would do anything significant—except, just possibly, improve the signal strength.
You can be absolutely sure, the first driver getting off anywhere sent the radar cops and manufacturers back to the lab, and that now the daily calibration, and test reports that are available in court include the CD factor. Cops don't like to lose. That's not what we pay them for.
Not speeding's easier, and less expensive than not getting caught.

Mr. Handsome is correct, the radar signal bounces of the largest area that it "see's" the front of the car or truck etc. A small reflective cd hung from the mirror does nothing except, as Bandit pointed out, blind the oncoming driver. Get rid of it, it's not cool just a pain to other drivers. eg old person cant see well, is blinded by a cd flashing in the window, then hits something, he is blamed for being old etc. Get rid of it.
I had never heard of this theory, I just thought that people with CD's hanging from their rear view mirror couldn't afford those expensive fuzzy dice.

Are those like the crown air fresheners the homies keep by the back window? I haven't seen the Taj Mahal Kleenex boxes before. There are more homies than hindus where I'm at.
I think buddy is referring to the circles or tracks on the CD on the underside which is suppose to interfere with the radar.
the interference is a well known effect when you try to bounce EM waves, light, radar, etc at circular patterns you get an interference pattern that bounces back that is unreadable to the sender.
when people counterfeit money using a scanner they have problems scanning the eyes of money because they have circular patterns in them. You can tell counterfet money by the eyes they cant reproduce the fine circular patterns in the eyes.
when scientists (NASA) was taking topgrahical maps of the surface using radar they found that farmers fields with circular pattrens were distorting the readings.
previous poster was right the CD is much too small to have an effect.

So are you saying that if someone were to epoxy a slew of CDs to the outside of his car that it would essentially become impossible to detect with radar? Or maybe a paint shop developing a circular glazing techinque that could replicate the effect? Do I see the next fad cresting on the horizon?
How amusing....

Yes but are you saying that if you have a front-end made of
CD-like material it could possibly work???
I sense a business opportunity!!!
Outlawed in a second...
Even if it could work and someone started to 'paint' people's cars to deflect or distrort radar... how long do you think it would be till it was outlawed. I think just like for example tinted windows are outlawed in some places they would outlaw this in a second.

They would Hawk, but by then we are already freaking millionaires.
The smartest thing would be some type of screen that you attach to the front bumper (like those mosquite screens), and if that works you can always remove them once its illegal.

radar detectors are illegal in Canada, asn. they will get confiscated and you face an extra charge if you get caught with one.
hanging CDs are dangerous for the driver as well as other drivers....the sunlight, others' high beams etc...its not worth the risk....and Spuds is correct, it does nothing to fool the radar gun!
