Type Of Car Seat Laws In New Mexico

There are different types of laws related to different types of seats in New Mexico. I’ll be going through the below for an easier understanding.

1. Rear Facing Car Seat

These sorts of seats are to be used by children under 4, below 35 pounds. These are the safest ones out of the bunch, especially the safest for someone as young as a 1-year-old child.

These provide the perfect protection, absorb most of the crash and provide support to the neck, head, and spine.

2. Forward Facing Car Seat

These seats are used when your child exceeds 35 pounds and is over the age of at least 3-4. These sorts of seats will teach your child the basics of properly sitting in a car.

They will work as a transition from one seat to the other. And will also even have a harness system that will protect them if and when an unlikely event of any kind might happen.

3. Booster Seat

A booster seat is used when your child is around 60 pounds and near the height of 4 feet and 9 inches.

These sorts of seats are just meant to boost your child and give them a height advantage so that they can be seated securely and comfortably with a seat belt within the car.
