It’s not just based on how old your child is or their weight. Did you know that a car seat may need to be replaced after an accident? But, not all accidents. According to the National Highway Traffic Safety Administration (NHTSA), you should consider the level of a crash to determine if the seat needs to be replaced or not.
If it is a moderate or severe crash, the seat should be replaced. If it is a minor crash, the seat does not need to be replaced. Here is how the NHTSA defines a minor crash and what to look for.
