Have you ever noticed that tiny little arrow that either points to the left or the right on your gas gauge? In case you said no, don’t worry, lots of people never noticed it until it was pointed out to them too. They’re not just there for decoration either, it actually has a very convenient use for drivers. These little arrows tell you which side your gas tank is on your car! This means that when you drive into a gasoline station, you know which side to pull up against the pumps. And even if you borrow a car or happen to rent one for a trip, then you don’t even have to check the car to know where you’ll need to fill ‘er up!
