When your gas light starts blinking, this is an indication that your vehicle is low on fuel. If you have a digital display, it may also say low fuel. Once the needle or gauge reaches the red zone, this means that you only have a few miles worth of gas left in your tank. If you see the gas light come on, it's best to find a gas station as soon as possible to fill up. Depending on how far you're driving, you may want to add more than just enough to get to the next station. No one wants to run out of gas!
