Dirty Or Covered Plate Ticket

Hello,

I was stopped for speeding initially but thankfully the officer took pity on me I guess and gave me a Dirty or Covered Plate Ticket instead. I am in NY and the past few days have been brutally cold. It snowed few days back.

I am debating whether to plead guilty or not. Since the Officer gave me a break should I just plead guilty with an explanation and pix showing I resolved the issue asap by cleaning the plates.

If I plead not guilty can the officer charge me for speeding in court even though it is not what the ticket is for?

Thank you in advance
