Rodger Oakes has more from Jefferson City.
The zero-tolerance law does not let minors lose their licenses as easily as adults. Adults can lose their license if they are stopped for any reason, such as a sobriety checkpoint.

In essence, the law, which was supposed to crackdown on underage drinking and driving, has set up lighter punishments for minors driving drunk.
From Jefferson City, I'm Rodger Oakes.
