A "Warrant To Collect" is not an arrest warrant.
If you received a YELLOW "WARRANT" in the mail, this is the city/town's 3rd attempt to collect your outstanding excise tax. The fees and interest on the bill are STATE MANDATED and may not be reduced or abated by the Deputy Collector. If you feel you are due an abatement, it is in your best interest to pay the bill as-is and then apply for an abatement and if you qualify you would then be refunded any fees and/or interest as dictated by your city/town.
If you received a GREEN "FINAL WARRANT", this is the last notice you will receive before your LICENSE and/or REGISTRATION will be FLAGGED/MARKED "NON-RENEW" at the RMV. This flag/mark will result in another fee and you will not be able to complete new/renew functions at the RMV.
