Does RI share points with NY (NY doesn't assess points for out of state violations, from personal experience - other states may be similar)? If it doesn't, pay the ticket, and privately hope a truck whacks the lying ass of a cop during a traffic stop. Karma can be a b*tch.

As far as pleading guilty, you can always plead not guilty. Though the judge is more likely to believe a cop than a citizen, sadly.
