A zero emissions vehicle is a car that doesn't make bad air when you drive it. You see, most cars use gasoline, which makes a lot of bad air that we breathe in and it can make our planet sick. But a zero emissions vehicle uses something else to move. Some of them use electricity, and some of them use hydrogen which is like a clean gas. When they move, they don't make any bad air. Think of a zero emissions vehicle like a toy car that doesn't need batteries or gas to move. It's like magic! This kind of car is very good for the planet because it means we don't have to breathe in bad air and it helps to keep our Earth healthy.
