If the load shifts, slow down smoothly and find a safe place to stop. Do not continue until it is secure; attempt re-securing only when safe. Stay clear of the collapse area and obtain competent help rather than opening a bulging curtain or entering beside the load. If the load threatens traffic or recovery would be dangerous, stop safely, call 999 and wait for responders.
