What are the child safety seat laws in Arizona?
According to Arizona law, all children under five years old must be properly secured in a child safety seat (including both cars and trucks). There are several different types of child safety seats, rear-facing infant seats, forward-facing toddler seats, and booster seats. Depending on your child’s age and size, you will need to use a different type of seat.
It is recommended that infants ride rear-facing until they are at least two years old or reach the maximum weight limit for their particular seat (whichever comes first). Toddlers should ride forward-facing once they outgrow their rear-facing seat. However, they should remain in a harnessed car seat until they reach the maximum weight or height limit.

Once kids have outgrown, they can then move to a booster seat. It is important to note that all children under the age of eight should ride in a booster seat regardless of their height or weight. Children who are taller than four feet nine inches and weigh over 80 pounds can graduate from using a booster completely.
Moreover, it is always safest for kids under thirteen years old to ride buckled up in some form – whether that means using just a lap/shoulder belt or being seated in an actual car seat/booster with both restraints (lap/shoulder belt and forward Facing Car Seats(LATCH)).
There are certain circumstances where exceptions – such as if there is not enough room for another passenger due to medical reasons or if all other seating positions are occupied by individuals who also meet one of these exceptions themselves. But generally speaking, it is required by law that any person operating a motor vehicle have all passengers under the age of five properly secured in a child safety seat.

Common myths about car seat safety in Arizona
There are many myths surrounding car seat safety, particularly when it comes to the law itself. For example, some people believe that as long as their child is buckled into a regular adult lap/shoulder belt, they will be fine during an accident – this is not true!
A lap/shoulder belt alone does not provide enough support for a child’s body, especially during a high-impact collision such as a head-on crash.
Additionally, booster seats are often thought of as being “just for small children” but actually anyone under the height of 4 feet 9 inches should be using one according to experts; even if your child seems “too big” for a booster, it’s always better to err on the side of caution when it comes to their safety while riding in the car!
