A motor vehicle is a machine that helps people travel from one place to another. It has an engine that makes it go, and four wheels to help it move on the ground.
When you get into a motor vehicle, you sit in a seat and use a steering wheel to control where you want to go. Your foot can press on pedals on the floor, one to make it go faster (the accelerator) and one to make it stop (the brake).
Motor vehicles can come in different shapes and sizes. Some are very big and carry lots of people, like a bus or a truck. Others are smaller and only carry a few people, like a car. Motor vehicles can use different types of fuel to make them go, like gasoline or electricity.
It's important to be safe when using a motor vehicle, which means wearing a seatbelt, following traffic rules, and always paying attention to the road while driving.
