Why should a driver check that a hazardous materials package's orientation markings, such as 'this side up' arrows, are followed during loading?

2. Orientation only matters for solid hazardous materials, never liquids
3. This check applies only to packages transported by air
4. Incorrect orientation could increase the risk of leakage, especially for liquids with a specific fill point or vent
