Do "Warnings" go on your driving record?

Was driving the TR...quickly...and got pulled over. The interesting thing is, the cop was very nice . I rolled down my window, and greeted him, "Good morning officer, how are you?"

"Fine, thanks!" "Did you know you didn't use your turn signal back there? License please"

"Sorry about that." Here you go...

He comes back, and gives me a computer generated "Warning Ticket." No fee. No foul.

Now, my driving record is spotless...I just don't get caught . Ususally when I get pulled over, being extremely polite always get me a warning, and never a ticket.

So, how long does a "warning" stay on your record????

Will I eventually get pulled over, and get lectured about the 10 warnings I have recieved in the past??? Or do these clear the system pretty fast?

Just curious...
