Overview of Car Seat Laws - Idaho

According to the Idaho Transportation Department, proper use of car seats can reduce the risk of fatal injury by 71% for infants and 54% for toddlers.

Car seat laws (Idaho) require that children under eight years old or 57 inches tall ride in a child restraint system, which includes rear-facing car seats, forward-facing car seats, and booster seats. The specific requirements vary depending on the child's age and weight.

Infants and Toddlers Under Two Years Old

They must ride in a rear-facing car seat until they reach the highest weight or height allowed by the car seat's manufacturer. For children between the ages of two and four, they must ride in a rear-facing or forward-facing car seat until they outgrow the height and weight limits of the car seat.

Children Between the Ages of Four and Eight

They must ride in a forward-facing car seat with a harness until they outgrow the height and weight limits of the car seat. Once they outgrow the forward-facing car seat, they must ride in a booster seat until they are at least 57 inches tall or eight years old.

Children Who Are at Least Eight Years Old 

This also involves children who are 57 inches tall. They may use a seat belt without a booster seat, but it is recommended to use a booster seat until the seat belt fits properly. It is also recommended that children under 13 years old ride in the back seat of the vehicle for added safety.

It is important to note that these laws are minimum requirements, and it is always recommended to follow the car seat manufacturer's guidelines for maximum safety.

5 Common Car Seat Mistakes to Avoid

When it comes to car seat safety, there are common driving mistakes that parents make that can compromise the effectiveness of the car seat in protecting their child in the event of an accident. Here are some common car seat mistakes to avoid:

  1. Using an incorrect type of car seat for a child's age and weight: It is crucial to ensure that the car seat fits the child's size and weight and meets federal safety standards.

  2. Improper installation of car seats: A car seat that is not installed correctly can fail to protect a child in the event of an accident. It is essential to read the car seat manual thoroughly and seek professional help if necessary to ensure proper installation.

  3. Failing to buckle up a child properly: The harness and straps should be snug and secure, with no slack or twists. It is also essential to ensure that the chest clip is in the correct position, aligned with the child's armpits.

  4. Using a car seat that has been in an accident: Even if there is no visible damage to the car seat, it may have internal damage that compromises its ability to protect a child in another accident.

  5. Using a car seat that is expired or damaged: Car seats have an expiration date, usually around six years from the date of manufacture, and should be replaced if they are damaged, have missing parts, or have been involved in a car accident.

Tips for Choosing the Right Car Seat

Choosing the right car seat can be overwhelming, but there are a few key factors to consider. First, consider the child's age and weight to determine the appropriate type of car seat. Look for car seats that meet federal safety standards, as these have been tested for their effectiveness in protecting children in a crash.

Ease of installation and use is also important to consider. Some car seats may be more difficult to install correctly, and some may have features that make them more user-friendly, such as adjustable straps or removable covers.

Lastly, consider the size of your vehicle and the number of car seats needed. Some car seats may be too large to fit comfortably in a smaller car, or you may need to fit multiple car seats in the back seat.
