Arizona Car Seat Laws Rear-Facing

The Arizona laws in sections 28-907 A do not specify the AZ rear-facing law. It just requires that a child who is under five years of age should be properly secured in a child restraint system.
That means the car seats should be used based on the manufacturers’ instructions. The Arizona car seat laws for rear-facing seem not strict on age, weight, or height.
But the minimum requirement in other States is that a child must be rear-facing for at least 1 year and 20 pounds. It’s a good idea to keep your kid rear-facing for as long as possible, better than the minimum standards.
But it’s not breaking the Arizona car seat rules if you put an 18-month infant in a forward-facing car seat.

Arizona Forward Facing Car Seat Laws
Arizona laws in sections 28-907 A and B do not specifically list the requirements for forward-facing child car seats either, but only ask the operators to use an appropriate child restraint system for children under five years old.
Except as provided in subsection H of this section, a person shall not operate a motor vehicle on the highways in this state when transporting a child who is under five years of age unless that child is properly secured in a child restraint system.

When can a child sit in the front seat in Arizona?
There is no age mentioned in the Arizona State Law for a child to sit in the front seat.
However, it’s NOT recommended to place children under the age of 13 years old in the front seat.

Most organizations recommend that children 12 and under always ride in the back seat. If for some reason your child must sit in the front seat (two-seat vehicles or pick-up trucks with tight extended cabs, for example) make sure that the passenger side airbag is either deactivated or operates on an automatic sensor turning it off under a certain weight application and the vehicle seat is pushed back as far as possible.

How much do you have to weigh to sit in the front seat in Arizona
As of this post’s last update in August 2023, Arizona law doesn’t specify a minimum weight requirement for children to sit in the front seat of a motor vehicle.
Typically, weight is not the deciding factor to put a child in the front seat. Instead, NHTSA advises you to follow this age rule – a child at least 13 years old can sit in the front seat of a car.
When can child sit in front seat Arizona
The best time to have your child sit in the front seat in Arizona is when your child is 13 years or older. Younger kids are safer to sit in the back seat instead of the front seat. So it’s always a good idea to put your child in the back seat before their 13th birthday.
However, if the three seats in the back are taken by younger kids, it would be okay to put the oldest one in the front seat, even though he or she does not reach 13 years old.
For example, you have four kids, one is nine years old. And the other three are under eight years of age. Then you can put the 9-year-old big kid in the front seat.
How tall to sit in front seat Arizona
Arizona car seat laws don’t have a word on the height requirement for a child to sit in the front seat of the car.
You’ll find only the 4 feet 9 inches in the rules, but that talks about the booster height requirement – your child should be at least 57 inches tall before getting out of a booster seat.
How old do you have to be to sit in the front seat in Arizona
The best practice is to have a child at least 13 years old sit in the front seat in Arizona. That’s also the common rule in many US states and the advice from National Highway Traffic Safety Administrative.
