Why is it important to check that the tank is not overfilled beyond its rated capacity, considering outage requirements?

Pick an answer

1. Outage requirements apply only to tanks carrying hazardous materials, not to water or other non-regulated liquids
2. Overfilling always improves the tank's stability while driving
3. Overfilling leaves no room for liquid expansion and increases the risk of a dangerous overflow or excess pressure
4. Filling to full rated capacity is always required by regulation
