Side Impact Standards: What They Mean for Your Child’s Safety

When it comes to keeping our little ones safe on the road, we all know that car seats are a must. But did you know that not all crashes happen head-on? Side-impact collisions can be just as dangerous—if not more so—because there’s less space between the child and the point of impact. That’s why updated federal safety standards are taking a closer look at how car seats perform in these scenarios. Let’s break down what this means for you and your child.

Side Impact Standards: What They Mean for Your Child’s Safety

Why Side Impact Testing Matters for Car Seat Safety

Not all crashes are the same. While front-impact crashes are more commonly tested, side impacts introduce different forces that can be especially dangerous for children. The new side impact test procedures—outlined in the updated FMVSS 213a standards—are designed to ensure that car seats provide the best possible protection from all angles.

In a side collision, a child can experience sudden movement toward the point of impact, which can increase the risk of head, neck, and torso injuries. The new standards help ensure that car seats are built to manage these forces effectively, giving caregivers more confidence in their child’s protection.

What’s New in the FMVSS 213a Standards?

More Realistic Crash Scenarios for Car Seats

The updated side impact standard considers:

• The Direction and Force of a Side Collision: Manufacturers now use test setups that better mimic real-world side crashes. This means that the forces acting on a car seat during a side impact are more realistic, helping to improve overall seat performance.
• Improved Test Equipment: Advanced crash test dummies, updated testing devices, and refined methods allow for a more accurate evaluation of how well a car seat protects a child in a side impact crash.

Stricter Performance Criteria for Car Seat Safety

The new side impact procedures also focus on:

• Enhanced Structural Integrity: Car seats are tested to ensure they maintain their shape and structure during a side impact crash. The goal is to minimize deformation so the seat remains intact and continues to protect your child. Additionally, the child’s head should stay within the car seat’s headrest, providing crucial support and minimizing the risk of head injury.
• Better Energy Absorption: The new tests measure how effectively a car seat absorbs crash energy. By dispersing crash forces away from a child, the risk of serious injury is significantly reduced.

Can You Keep Using Your Current Car Seat?

If you already own a car seat, you may be wondering if you need to replace it. The good news is that car seats manufactured before the compliance date remain legal to use, as long as they have not expired and continue to meet all other car seat safety guidelines. However, parents should be aware that older models might not have undergone the new side impact testing, which means they may not offer the same level of protection in these types of crashes.

Do You Need to Buy a New Car Seat?

Not necessarily. If your child’s car seat is still within its expiration date, has not been in an accident, and meets current safety guidelines, you can continue using it. However, if you are shopping for a new car seat, consider purchasing one that meets the updated FMVSS 213a standards to ensure your child benefits from the latest car seat safety advancements.

June 30, 2025 Compliance Date – What It Means

The compliance date for the new car seat regulations is June 30, 2025. After this date, all newly manufactured car seats must meet the updated side impact testing requirements. Any car seat made before this date can still be sold and used legally, but only the newer models will be required to pass the enhanced testing criteria.

What Changes Will We See in Car Seats?

With the updated side impact testing, we can expect some notable car seat design changes, including:

• Reinforced side-impact protection with improved energy-absorbing materials.
• Enhanced headrest and side-wing support to minimize movement in a car crash.
• Possible updates to weight limits and seat dimensions to accommodate revised testing standards.

In some cases, these changes will be visible to consumers. Manufacturers may redesign their car seats to meet the new side impact regulations, which could result in noticeable differences in shape, padding, and side-impact protection features. However, some brands may have already been incorporating these improvements into their models before the regulations were officially updated.

Label Examples – How to Identify a Compliant Car Seat

To help consumers identify compliant car seats, manufacturers will likely update their product labels to reflect FMVSS 213a compliance. Look for labels that specify side-impact testing and ensure the car seat meets all updated federal safety standards before purchasing.

Expected Changes in Car Seat Limits

The new side impact standards will also influence car seat weight limits:

• Forward-facing car seats must have a minimum weight limit of 26.5 lbs to meet the new standard.
• Infant car seats will be limited to a maximum of 30 lbs, unless manufacturers conduct additional testing with the 3-year-old crash dummy to allow for a higher limit.

Testing Constraints: What’s Not Covered?

The new regulation requires manufacturers to complete side impact testing for occupants weighing less than 40 lbs. This means that all infant car seats and convertible car seats must pass the new tests using smaller crash test dummies that represent a 12-month-old and a 3-year-old dummy. However, testing is not performed with larger dummies that represent older children in harnessed seats, nor is it conducted for belt-positioning booster seats. Since all booster seats have a minimum weight requirement of 40 lbs, they are exempt from this regulation.

Understanding the Impact: What Really Happens in a Car Crash

While we've discussed the importance of side-impact testing and updated car seat standards, it’s equally crucial to grasp the overall dynamics of a car crash. Every collision involves a series of rapid, complex events that can significantly affect safety outcomes. To delve deeper into these critical moments, check out our comprehensive guide on what happens in a car crash.

This is Why Expiration Dates Matter

Expiration dates on car seats exist for a reason, and it’s not just about wear and tear. As safety standards evolve, new testing procedures, materials, and designs make older seats less effective compared to newer models. While an expired car seat may still physically look fine, it might not provide the same level of protection due to outdated safety features and materials that degrade over time. Ensuring your car seat is within its expiration date means your child is benefiting from the latest safety advancements.

Final Thoughts – What This Means for Car Seat Safety

At the end of the day, nothing is more important than your child’s car seat safety. The updated side impact standards reflect a commitment to real-world protection, ensuring that car seats offer balanced protection no matter how a crash might occur.
