The distance you can drive after the low fuel light comes on varies depending on the make, model, and year of your vehicle, as well as your driving habits and conditions. However, most vehicles can travel between 30 and 50 miles after the low fuel light illuminates. Some newer models may even be able to go as far as 70 miles.
As a general rule of thumb, it's best to fill up your gas tank as soon as possible when you see the low fuel light come on. This will help you avoid running out of gas, which can be dangerous and inconvenient. If you do run out of gas, you will need to pull over to the side of the road and wait for assistance.
