When the fuel gauge yellow light flashes, you can still drive approximately 20 kilometers. Continuing to drive after the fuel warning light comes on is referred to as low-fuel driving. It is advisable to refuel immediately after the warning light illuminates, as low-fuel driving can damage the fuel pump. The fuel pump generates heat during operation, and when driving with low fuel, the remaining gasoline cannot cover the fuel pump, preventing effective heat dissipation and shortening its service life. For safety reasons, the appropriate time to refuel is from when the fuel warning light comes on until the fuel gauge needle reaches zero. For most vehicle models, when the needle points to zero or the computer displays a remaining range of zero, driving in a fuel-efficient manner for 10 to 20 kilometers is possible before the fuel warning light comes on, reminding the owner to refuel as soon as possible.

Last time when my car's fuel gauge light was flashing yellow, I was really nervous. I asked a mechanic friend, who said the mileage you can drive varies by car—small cars might go 30 km, while SUVs could reach 60 km, and it also depends on how you drive. Cruising on the highway saves fuel, but stop-and-go traffic in the city burns it faster. The light flashing is a warning to refuel ASAP—don’t hesitate, or you risk stalling on the road, which is a big hassle. That time, I drove 40 km to find a station, and afterward, I learned to check the fuel level regularly and not wait until the light comes on. Safety first—better to act early and save the worry.

Having driven for decades, I've seen the fuel gauge light flash many times, indicating that the fuel is nearly depleted. A regular car typically has about 30-50 kilometers of range left, but many factors affect this: the size of the car, road conditions, and steepness of slopes all play a role. For example, heavy loads or using the air conditioning consume more fuel, and I've experienced situations where the car could only go 20 kilometers. Nowadays, I always plan my trips in advance, slow down when the light flashes, and drive steadily to the nearest gas station, avoiding any high-speed dashes. Remember one thing: don't gamble with luck, refuel in time to avoid breaking down.

I have a daily commuter car at home, and I get nervous whenever the fuel gauge yellow light comes on. My husband says it can still go about 40 kilometers, but I insist on finding a gas station immediately—especially when traveling with our child, we can't take risks. Most cars are designed with a buffer, allowing you to drive 30-50 kilometers without issue, but this range shrinks in rainy weather or mountainous roads. My habit is to reduce the air conditioning fan speed to lower fuel consumption as soon as the light comes on, squeezing out a bit more mileage. The key is not to delay: safety is always the bottom line for family trips.

I have some interest in cars. When the fuel gauge light flashes, the signal designer actually left some leeway. Generally, it can last for about 40 kilometers, supported by the residual fuel at the bottom of the tank. However, factors like driving habits—such as sudden acceleration or carrying extra load—can increase fuel consumption. I once drove 50 kilometers slowly after the light flashed to refuel, but it's still recommended not to wait until the last liter of fuel is used up. Check the car's maintenance records to ensure the sensors are functioning properly. Next time the light comes on, don't hesitate—address it early.
