I was told by a court office person when you plea in writing to not make excuses. They have heard them all. The best thing to do is say something along the lines of (if it applies) you were new to the area and did not realize your speed was rising.
Also, i was told that you can make the court sometimes feel bad for you if you put in your plea that you are requesting a non moving point reduction due to the fact that you drive primarly for your job and a point infraction can put you at risk of losing your job.
I did that for my speeding ticket up by the 1,000 islands and I got it reduced to a two point failure to obey a lawful order. Mine was 78/65
