Legal Answers
429 Questions Answered

Q. How will having no "priors" on my records affect my sentencing on a felony now?
A: If you have no prior felonies on your record, or none within the last ten years, you are eligible for the lowest range of sentencing when the presiding judge sentences you.
Q. How do I calculate the time from a previous felony conviction for purposes of sentencing on a new case?
A: The time from your last felony conviction begins to run on the date that you are released from prison on the previous conviction.
Q. How many classifications of misdemeanors are there in New York?
A: There are A and B misdemeanors, and unclassified misdemeanors.
Q. How long can I possibly be sentenced on a Class B felony?
A: The maximum sentence on a Class B felony is 25 years in state prison.
Q. What level felony is criminal possession of a controlled substance in the second degree?
A: Criminal possession of a controlled substance in the second degree is an A-11 felony.
Q. Is there any chance that I can plea bargain my DWAI to a non-drinking infraction?
A: No, there is no possibility of a non-alcohol plea bargain for any alcohol infraction or crime.
Q. I am 19 years old and I just was found guilty of a DWAI. How long will I lose my license for?
A: Since you are under the age of 21, the license revocation for a DWAI is a minimum of one year. For adults, there is a 90 day license suspension on a first time DWAI.
Q. What proof is there that I completed the Drinking Driver Program and who receives it?
A: A "Notice of Completion" will be sent to the Department of Motor Vehicles when you successfully complete the program. The DMV will then determine if you are eligible to be reinstated or not. For example, if there was a refusal to take a chemical test, you would have to wait a full year before being eligible to obtain your full license back (assuming this was first time refusal).
Q. How long is the Drinking Driver Program that the Judge ordered me to take?
A: The class is 7 weeks, and each session lasts approximately two to three hours. Total classroom time is 16 hours to complete the program.
