What is the primary duty of a commercial transport driver before departing on any cross-country trip across Afghanistan?

1. Verify vehicle mechanical roadworthiness, secure all cargo within legal limits, inspect emergency safety gear, verify valid commercial licence and permits, and plan route/weather safety
2. Rely on the workshop's last service and skip the walkaround to save time
3. Load to the maximum the springs will physically carry rather than the registered limit
4. Plan the longest possible single stint so the trip finishes in one day
