A filling station is a place where we go to fill up our cars with gas when they are running low on fuel. When we drive our cars, they use up the fuel in the tank like how we drink from our water bottles.
At a filling station, there are usually gas pumps that have nozzles that we put into our car's gas tank to fill it up with fuel. The fuel comes from big tanks under the ground which are connected by pipes to the gas pumps.
Filling stations also have other things we might need for our car, like windshield washer fluid, oil, or air for our tires. Some filling stations even have convenience stores where we can buy snacks, drinks, or other things we might need while driving.
It's important to remember that we should never play with the gas pumps at a filling station because they are dangerous and can cause accidents. It's best to let grown-ups handle the pumping of gas.
