These license plates are too raunchy for Iowa's roads

Catch up fast: Since 2004, the Iowa Department of Transportation has maintained a database of no-no license plates.

• Applications attempting to use one of the more than 5,300 terms on the list get automatically rejected.

State of play: The database includes characters or phrases considered to be offensive, inflammatory or sexual in connotation.

• Punctuation marks, characters that conflict with the state's license numbering system or those referencing illegal substances are also rejected.

Zoom in: Most of the nearly 30 new database entries last year seemed innocent, according to a public records request obtained by Axios.
