Need some Help with a Ticket

[Minsu]

If this is in wrong section sorry mods.

So my mother got pulled over for speeding, and the cop told her not to worry about it and that he will give her a ticket with no points and its worth 85 dollars. My mother re-confirmed with the cop and asked if its no points and he assured her its no points.

So my mom brings the ticket home, i look it up and the ticket is for failure to keep right...what does that even mean, well its a two point ticket. The ticket is 185 and its worth 2 points. Its not a speeding ticket but its still two points and my moms english is lacking so taking care of it. I would like to see if i can get the no points and just pay the ticket but im not too sure, ive never gotten a moving violation ticket so im really not sure.

So what should I do in this situation, Im really not sure what to do here. As in would it better to eat the two points instead of argueing or if its better to see what my options are?
