When performing multiple partial deliveries throughout a delivery route, what must the driver do after unloading each individual consignment?

1. Drive faster to make up for lost unloading time
2. Keep all remaining cargo loose to speed up the next delivery stop
3. Immediately turn off the tachograph to avoid recording working time
4. Re-evaluate weight distribution across axles, re-position remaining cargo if necessary to prevent steer-axle or drive-axle overload, and re-tension all securing lashings
