When refueling, the car should be turned off. Here are the specific reasons: Reasons for turning off the car during refueling: Gasoline is an electrolyte. If the vehicle is not turned off during the refueling process, although the car is not moving forward, the internal engine and other instruments are still in operation. Not turning off the car while refueling may cause the operating instruments to leak electricity, leading to short circuits or other electrical issues. Regulations at gas stations during refueling: Gas stations also strictly prohibit wearing, removing, or slapping synthetic fiber clothing and using mobile phones at the refueling site. Gas stations are most afraid of open flames and static electricity. Synthetic fiber clothing is prone to generating static electricity, so do not get out of the car to slap clothing during refueling to avoid the risk of static electricity igniting gasoline.

As a seasoned driver with over twenty years of experience, I fully understand the importance of turning off the engine when refueling. Every time I go to the gas station, I make it a habit to shut off the engine before approaching the fuel pump, ensuring everything is quiet. This is because running engines with hot components or sparks could ignite gasoline vapors, posing a fire or even explosion risk—it's a fundamental safety rule. I remember once rushing to refuel and forgetting to turn off the engine, only realizing my mistake after a stern warning from the gas station attendant. Since then, I've made it a strict habit. Turning off the engine also gives the car a brief rest, reducing wear and extending its lifespan. During refueling, I also turn off electronic devices like the stereo or air conditioning to minimize any potential spark sources. Safe driving starts with small details—never risk safety to save time.

When I first got my driver's license, my knowledge about cars was quite limited, but my instructor repeatedly emphasized that the engine must be turned off before refueling, calling it the first safety lesson for beginners. Once, a friend accidentally mentioned his accident experience: a small fire was sparked by refueling without turning off the engine, frightening everyone. Now, every time I refuel, I carefully turn off the engine and check if the fuel cap is tightly closed to prevent leaks. Although the process only takes a few minutes, it can prevent major disasters. Beginners should especially pay attention to these details and not find them troublesome. Turning off the engine also allows it to cool down, avoiding overheating issues. Developing good habits makes driving much more reassuring.

From a scientific perspective, turning off the engine while refueling is mandatory. When the engine is running, high-temperature components or electrical sparks could ignite gasoline, leading to dangerous explosions. I recall frequent news reports about such accidents, so I strictly adhere to this rule. The moment the engine is turned off, combustion stops, eliminating potential ignition sources. I also avoid using my during refueling to prevent static sparks. Simple actions like these can be life-saving. Once it becomes a habit, you'll never forget.

I've always been concerned about environmental protection and saving costs, so turning off the engine while refueling isn't just for safety. Idling the engine increases fuel consumption and emits greenhouse gases. Turning it off for a few minutes causes no loss but reduces waste. I've estimated that if everyone did this, the country could save a considerable amount of fuel and reduce pollution. In terms of safety, gasoline vapors are explosive, so this rule is well-designed. I've never violated it and always wait quietly for the refueling to complete. Small choices can have big impacts, benefiting both my wallet and the planet.

I always keep safety tips in mind, such as turning off the engine when refueling. I've seen too many accidents caused by not turning it off. Once, a gas station employee said they would monitor customers to ensure the engine was off, otherwise they would refuse service or impose a fine. This protects everyone. I make it a habit to turn off the engine, engage the handbrake, and confirm safety before starting to refuel. Small habits become second nature, making driving more reassuring. Prevention is always more important than remedy, especially in high-risk situations.
