Illinois Booster Seat Laws


There’s no specific booster seat law for the state of Illinois. The law is a blanket law that states that all kids under the age of 8 have to be secured with the appropriate car seat.

In this case, between the ages of 4 and 8, a booster seat is required if the child meets all weight and height requirements.

Also depending on which authority you’re looking at, some recommend using a booster seat until the age of 12. In these circumstances, you should choose that restraint option that offers the most protection.


Illinois Rear-facing Car Seat Laws

According to the law, all kids under the age of 2 weighing less than 40 pounds or being shorter than 40” have to ride in a rear-facing car seat.

As we know, rear-facing car seats offer the most protection, so you don’t have to hurry with the upgrade and keep your child in rear-facing until they have outgrown their seat.


Illinois Forward-facing Car Seat Laws

Since the law is a blanket type, it means that after the child has outgrown a rear-facing car seat, they can be upgraded to a forward-facing car seat.

This usually happens between the ages of 2 to 4. Also, if a child is above the 40-pound weight limit, they can be secured with a seat belt.


Illinois Taxi Car Seat Laws

According to law, a taxi is a commercial vehicle transporting less than 10 people is exempt from the above-mentioned car seat laws, so they are exempt. Now, if you want to keep your child secure on short rides, it means that you have to bring your own car seat.
