Keeping your young children safe and secure in your vehicle is now harder with potentially unsafe car seats.They are untested and unregulated. Some are even called counterfeits.You don't want to find out you have one when a crash happens.An 8 On Your Side investigation shows you what to look for on your car seats to make sure they properly protect your children.As the father of two little girls, Chris Good knows how important the right car seat is."It's just knowing, having that peace of mind knowing that we're doing what we can to make sure they're safe," Good said.But choosing the right one isn't always easy.The Georgia Governor's Office of Highway Safety recently posted a photo of what it calls a counterfeit car seat, adding it's not compliant with Federal Motor Vehicle Safety Standards.Car seat safety expert Fritzi Shreffler said a growing number of these car seats are now available."Unfortunately, there's always somebody out there looking to make a buck," she said.While non-compliant seats may look OK, there are some things you should look out for – beginning with the price point. If it seems like it's too good of a deal, it probably is."If you see that it's coming from a vendor and maybe it's coming from another country, that's an immediate red flag of, 'This might not be right,'" Schreffler said.But buyer beware. There are car seats that do not meet federal regulations for sale right now on reputable websites and in brick-and-mortar stores. You have to pay attention to the details."If it seems flimsy, if you can bend the plastic, that is probably not a certified car seat," Schreffler said.Child restraint systems that meet regulations will say so – usually on the label.The seats will also include a registration card and will be labeled with a model number, the date it was manufactured and its expiration. You should also look for seats with chest clips."If you don't see that, that is not a legal seat to be used in the United States," Schreffler said.If in doubt, ask questions."Making sure your child is properly restrained in a vehicle is the number one thing you can do to ensure their safety in the event of a crash," Schreffler said.The Department of Transportation has a tool to help you find the right car seat for your child.
