Moving violation question?????? trying to get into trucking!!!!

so im wondering about the 3 year rule with companies about moving violations. when they say no careless or reckless tickets in the past 3 years does that mean 3 years from the day you got the ticket?? because i went to court and fought my ticket (careless driving) and got it dropped down to unsafe operation but i went to court like 8months after the ticket was issued. so would the 3 years start when i got the ticket issued or when i got the ticket downgraded? please anyone who knows id apperciate it very much. im looking to get on with MCT or Millis transfer ASAP ive been wanting to drive for soooooo long and now im finnaly old enough and in the position to be able to go OTR without having a GF or apartment to pay and whatnot so im looking to get going asap

 

thanks guys im going to go to my dmv and get a print out of my driving record and see what exactly is on there
