Hey y'all!

I received a traffic ticket (Changing lanes not in safety), and was planning to request the Deferred Disposition option.

I know that if I were to request this option and not get another violation within 90 days, the ticket will get dismissed. I have 2 questions:

1. When does the 90 days start. 90 days from the traffic violation? Or the day the request gets accepted?
2. If I were to get another ticket #2 let's say 6 months later, can I request to take the Mandatory DSC/MOTC course to take care of the 2nd ticket? I'm trying to minimize the amount of points I get on my license, but want to be prepared in case I get a ticket for petty things like this lane change. To my understanding the DSC can only be taken when I haven't gotten a violation within 12 months, but I dunno if the first ticket would be considered a ticket if it's dismissed through the Deferred Dispostion.

Thanks you guys!
