Frequently Asked Questions

What is the most common car seat law?

Most states require a booster until age 8 or 4’9" (57 in) tall, with rear-facing until age 1-2. Use the checker above for your exact state.

When can my child use a seat belt only?

Usually at age 8 or 4’9" — but only if the belt fits correctly. See the seat belt laws guide.

Are car seat laws different for taxis?

Some states exempt taxis; rideshare is usually treated like a private car. See taxi and rideshare rules.
