If the warrant has been entered into NCIC, the warrant will appear anywhere in the country within the designated regions as requested by the agency entering the data. Local warrants will appear based upon whatever criteria the local agencies and database has set for this ... sometimes they may have a year limit, other times it may be forever. Traffic information is likewise limited by state law and policy ... in my state the typical DMV records search by an officer in the field will reveal a 7 year history.
