Regarding the change of license when renewing, what can happen if my answer is yes when completing the voter registration?
Then you will complete your voter registration application as part of the renewal transaction and if you are a resident of Bronx, Kings Brooklyn, New York Manhattan, Queens, Richmond Staten Island, Dutchess, Nassau, Orange, Putnam, Rockland, Suffolk and Westchester then you will have to pay a MCTD fee of $1 for every 6 months license will be in effect.
OK, now for the driver's license course, do you have any information on how I should practice before taking the test?
Yes, I can link you to a page where you can learn how to prepare for your road test.
