Police will begin ticketing drivers on Wednesday if they have passengers younger than 7 not in booster seats.

Kentucky State Police Capt. William Marks said violators can be fined $30.

The state's booster seat law calls for children younger than 7 who are between 40 and 50 inches tall to ride in booster seats.

Police have been issuing courtesy warnings since the law took effect last year. Marks said that ended as of Tuesday. Now violators are being handed real tickets.
