Just when your child had finally graduated from having to use a car seat, it looks like he or she will have go right back in one -- if you drive in California.

California becomes the latest state to require children to use a booster seat in a vehicle until they are 8 years old, the San Jose Mercury News reports. Previously, they could stop using car seats at age 6, or over 60 pounds.

Kids still have to ride in the back seat, as well. Getting a ticket for violating the law will cost drivers at least $475.

The new law will apply to children under age 8 or under the height of 4 feet, 9 inches, the Daily Calistogan says. If they are bigger, they can be belted in the rear seat.
