Unless there are serious injuries or death, DUI in New Jersey is not a crime, but instead of traffic violation. If a person is arrested for DUI in New Jersey, they are not fingerprinted, they are not read their Miranda rights, and the record of a New Jersey DUI arrest or conviction is not part of the FBI's NCIC database. Because of this, a New Jersey DUI will NOT show up when you try to enter Canada. Also, if asked whether you have ever been arrested or convicted of a crime, the answer is 'NO', since a New Jersey DUI is not a criminal offense.
