What must you remember when refuelling?

You answered correctly! When refueling, it is important not to breathe in any fuel fumes because they are harmful to your health, and not to continue refueling once the tank is full and the nozzle has automatically switched off—this prevents overfilling, which can cause spills and environmental harm. You should not fill the tank to the brim after the nozzle switches off, as this can damage the vehicle's emissions system and is against environmental guidelines. Remembering these rules will help keep you and the environment safe at the fuel station.
