Car rental is when you "borrow" a car from a company for a certain amount of time. It's like when you borrow a toy from a friend, but instead, you borrow a car from a big company.
Before you can borrow a car, you have to pay some money to the company. This is called a rental fee. When you pay the rental fee, the company lets you use one of their cars.
There are different kinds of cars to choose from, like small cars or big cars, depending on what you need. Some cars are good for just driving around the city, while others are better for long drives or adventures.
Once you have chosen a car, you have to sign some papers. These papers tell you all the rules you have to follow while you have the car. For example, you have to return the car on time and in good condition.
When you have the car, you can drive it anywhere you want to go. But you have to be careful and follow the rules of the road. You also have to take good care of the car, so it doesn't get damaged or dirty.
When you are finished with the car, you have to return it to the company. The company will check the car to make sure everything is okay. If there are any problems, they might charge you extra money to fix it.
That's basically what car rental is like. It's a way to use a car for a short time when you don't have one of your own. It can be really helpful if you need to go somewhere and don't have your own car or if your car is being fixed.
