Thanks Bats.
I do the same thing as you do, but I typically get more than one ticket every 18 months. In fact, I had one about 8 months ago, and then two more within the past two months.
In the past, I used to opt for traffic school everytime, even if it was before the 18 month period, and it did not show the point in my DMV records. However, I went to the courts three weeks ago, and was told that as of like 8 months ago, they are actually checking to see if it has been 18 months. You can opt to pay for traffic school, and attend school, but after doing all that, you will still see the point on your record. So it's best not to do it from now on.
I'm now having the two violations fought via written declaration, and then if I don't win that, to hire a lawyer to represent me in court after the continuance.
Thanks for sharing. I thought there was some other magical method in which you were keeping the insurance companies from seeing the violations.
Back on topic:
Redwings explained it perfectly. Some radar detectors manufacturers have anti-detector detectors (like the Escort Passport 9500ix, and the top-of-the-line Beltronics), but to have it hidden and turned off when pulled over is a great idea.
