why are registration tickets considered as a point on ur record?

[HyperTek]

Ok so i got a registration ticket back in dec 07 in my old benz (registration was paid for, i just never passed smog so i been rolling on window temps, til that time i got the ticket i didnt have a valid window temp *i traded the car later that month so i just paid the fine*. I thought it was such a minor violation that i totally forgot about it.

Til today my mom gets an insurance quote *i still live at home so im still under her policy*, and that ticket came up, which would cost me alot more for my end of the bargain because the insurance rep said it is considered a point.

Now i totally forgot about that ticket since i haven't heard of it being a problem with the different insurance companies we've had since, even when i registered the rx7.

My mom wants to drop me from the policy since it would be cheaper for her to move to a new insurance company since she would be getting a better rate for herself as compared to what she is getting as a renewel FOR HER SIDE. Im hoping i could call our current company and just move onto my own policy at the same rate i was paying since they already have my record.
