At gas stations, you can often see cars being refueled with the engine running. Gas station attendants say they do this not out of laziness, but out of fear, they are afraid that the engine will not start later.
At the same time, the rules at gas stations are clear: the engine must be turned off. A running engine can cause sparks and ignition of fuel vapors, especially in cars with a carburetor system or tuned exhaust.
Modern cars are better protected, but the requirements remain the same for everyone. In addition, when the engine is running, fuel level sensors may give inaccurate data, and the system does not update the readings while the engine is running.
Gas station attendants remind: employees have the right to refuse service if the driver refuses to turn off the engine. This is a safety rule, not a formality - one wrong step can cost too much.
