Rear-view mirror

A rear-view mirror is a little mirror that helps you see what's behind you when you're driving a car. It sits in the middle of the windshield at the top and you can adjust it to get a better view of what's happening behind you. When you look in the rear-view mirror, you can see cars that are driving behind you, which is really helpful when you want to change lanes or turn. It's important to use your rear-view mirror all the time when you're driving, so that you can stay safe and avoid accidents.
