The law does not state that kids have to be in a booster seat until they are 60lbs. It says 6 OR 60lbs. You can verify this by calling any CHP or even checking their website on-line. I have a 7 yr old that doesn't weigh 60lbs, but because she is 6, she is legal without any seat. It is different than the 4 AND 40lb rule with car seats. So, depending on your comfort level, you can actually pull your kids 6 & older out of booster seats. It is more of a height issue anyway. They are trying to change the law to add a height requirement of like 54in or something like that but it hasn't gone through yet.
