Amends existing law to clarify terminology regarding sheriffs.

This legislation is to correct terminology in Idaho Code by removing all references to a sheriff's department and replacing each reference with terminology indicating a sheriff's office, within the meaning of an elected office of sheriff. It also amends Idaho Code by adding a new section and revising Idaho Transportation Department's standard two-letter exempt license plate designators table by replacing "SD" for Sheriff's Department with "SO" for Sheriff's Office. These corrections serve to instruct sheriffs, their staff, and others to avoid the use of 'sheriff's department' to identify the 'sheriff's office' where this incorrect terminology engenders a misunderstanding as to the true nature of the elected office of sheriff within county government.
