A car’s safest seat “also depends on the vehicle that you’re in,” says Byron Bloch, an auto safety expert and advocate. Is it a front impact?”Here’s what you need to know about how to pick the safest vehicle and where to sit in it. In short, if you’re traveling with a little passenger, make sure to put them in your car’s safest seat: the rear middle. “You want all of the side windows and the sunroof to be laminated glass,” Bloch says. Aim to buy the safest car you can and make sure you keep kids or more vulnerable passengers in the rear middle seat.
