It varies from locale to locale.
Here in North Carolina, I've had quite a few tickets over the years. In Guilford County (Greensboro) where I live, I've never been convicted on anything and had it go on my record. An attorney can get it dropped down to improper equipment, which is just a fine (plus the attorney's cost). Or you can appear in court yourself and agree to go to a driving school, that will be 4 or 8 hours depending on if you have taken the course within the past 3 years, I think. Doing so will also get your ticket reduced to improper equipment. What do they care? The local jurisdiction gets their money either way.
In the county immediately north (Rockingham), I got a ticket and only had to take a copy of my clean driving record in order to get it reduced to improper equipment. If the record was not clean, there would have been the driving school option. Again, they still get money.
Mecklenburg County (Charlotte) was completely different. Things may have changed, I don't know, but my ticket in 97 wasn't something I could get completely out of. The attorney I hired told me that the DA would not allow one of his ADAs to reduce a ticket to a non-moving violation like improper equipment, so the best I could hope for is a reduction on the speed. I ended up getting my ticket dropped from 75 in a 55 to 64 in a 55, which (in NC, at least) spared me an increase in insurance unless I got another ticket.
The highest I've ever been ticketed for is 78 in a 55, by the way. I don't know what you're dealing with there.
