County agencies

All Iowa Sheriff's Departments use the same markings and graphics on their patrol vehicles aside from each county having its respective name on the patrol vehicle before the word "County" under the "SHERIFF" door markings. All road deputies in the state also wear the same brown uniforms. All counties have the same shoulder patches with the county name at the top, a 7 point gold star with "IOWA" in the middle, and "SHERIFF" at the bottom. Polk County Deputies may sometimes be seen with Silver 7-point stars on their uniforms. Many years ago they were sent the wrong color patches due to a shipping or order mistake and haven't bothered to fix the 'tradition' in the years since.
