BALTIMORE (AP) — Maryland will gladly take $50 a year from residents who want vanity license plates. However, one can’t put whatever one wants on a tag.

There are more than 4,000 words, phrases and letter-number combinations that the Motor Vehicle Administration has on its Objectionable Plate List.

The Baltimore Sun reports most of the list is too vulgar for publication.

When someone applies for a vanity tag online, a computer checks to see if there is a block.

Not all banned words are scatological or sexual. FBI and CIA are banned, as are HEROIN or KILLALL.
