A driver calculates 25 500 kg of theoretical payload, but placing that mass against the headboard would exceed the drive-axle limit by 2 000 kg. What does Goal 1.4 require?

1. Load the full 25 500 kg anyway because total combination mass is still legal
2. Move everything onto the trailer kingpin regardless of steering-axle load
3. Ignore axle limits when using an automatic gearbox
4. Redistribute or reduce the load so no axle is overloaded, even if that means carrying less than the theoretical payload
