Yes, a DUI conviction in one state can affect your driver's license in another state. Both New Jersey and New York are part of the Interstate Driver’s License Compact (IDLC), which is an agreement between 45 states to share information about driving-related offenses, such as DUI and DWI. If you get convicted of a DUI in another state, your home state is likely to learn about it and enforce appropriate penalties, such as license suspension or revocation, fines, and completion of DUI education programs.
