How far can you drive after low fuel light comes on?

If you fail to keep an eye on your fuel level while driving, your car could eventually come to a stop. When a car is about to run out of fuel, a warning indicator commonly known as the low fuel light illuminates on the dashboard.

But how far can you actually drive once this light comes on? The answer can be useful if there isn’t a fuel station nearby. However, there is no single answer as it depends on several factors including the car’s make and model, model year, driving habits, fuel efficiency and road conditions.

According to experts, once the low fuel warning light turns on, the vehicle cannot travel very far. The good news, however, is that it can usually go farther than many people expect.

Experts say the warning light typically comes on when the fuel tank has around 10 to 15 percent of its capacity remaining. On average, small cars can travel about 20 to 30 miles (32–48 km) after the light comes on while larger vehicles may cover up to 50 miles (80 km).

However, if the vehicle is old or the road conditions are poor, the remaining driving range may be significantly shorter. Cold weather can also increase fuel consumption reducing the distance the car can travel after the warning light appears.

Experts further caution that continuing to drive for an extended period after the low fuel light comes on may damage the engine although driving a few additional miles is generally unlikely to cause any harm.
