Should the engine be turned off when refueling the car?

[Frodo]

When refueling the car, the engine needs to be turned off. Dangers of refueling without turning off the engine: When a motor vehicle is being refueled at a gas station, if the engine is not turned off, although the vehicle body is not moving, the engine is still running at high speed. A running engine inevitably involves electric current flow, which can be extremely dangerous if there is a short circuit or leakage in the electrical system at this time. Refueling precautions: All vehicles must enter the gas station at a slow speed before refueling and exit slowly after refueling. During refueling, the vehicle must be turned off before refueling begins. During the refueling process, if the attendant has not turned off the fuel nozzle, the car must absolutely not be started.
