How far can you drive when the fuel gauge is in the red zone?

According to standard fuel consumption calculations, when the fuel gauge light comes on (i.e., the needle enters the red zone), the car can typically travel approximately 50–90 kilometers. Driving within 20 kilometers after the fuel light turns on is generally safe, but beyond this range, caution is advised. It is best to prepare gasoline in advance. Additional information: 1. When the fuel warning light illuminates, it indicates that the fuel level has dropped below the fuel pump. The exposed fuel pump begins to overheat due to the lack of fuel for cooling. Continuing to drive at this point further exposes the fuel pump, worsening the overheating. Many drivers continue driving even after the warning light comes on (sometimes until the fuel runs out), which is not advisable. 2. When the fuel tank's yellow warning light appears, it is recommended to refuel at the nearest gas station promptly. This not only prevents the risk of running out of fuel mid-journey but also avoids potential damage to the vehicle. When the fuel level falls below the fuel pump, the pump lacks sufficient fuel for cooling. The more the fuel is depleted, the more severe the overheating becomes, ultimately shortening the fuel pump's lifespan.
When the fuel gauge needle dips into the red zone, based on years of driving experience, I can tell you there's usually about 30 to 50 kilometers left in the tank, depending on the car model and road conditions. My old sedan once barely made it 40 kilometers after the warning light came on before nearly stalling on the highway. I don't recommend pushing it this way because consistently low fuel levels expose the fuel pump to air, causing overheating and potential damage to engine components, not to mention sucking up sediment from the tank bottom. To avoid emergencies, I've made it a habit to head straight to the nearest gas station when the light comes on, or use navigation apps to plan fuel stops in advance. After all, safety comes first—never gamble with luck.
