The magic number is eight and anyone younger than that in Wisconsin is going to have to be in a seat. Wisconsin parents will soon have to obey a new law. Wisconsin Governor Jim Doyle plans to sign a bill Monday that would require children younger than eight to sit in booster seats when they ride in cars. That's a departure from current state law, which says children ages four through eight can sit in booster seats or use safety belts. Supporters say too many
eight-and-unders are still too small to use seat belts safely. Opponents say the law is confusing and unenforceable.
