What precaution should be taken when hauling loads that could fall or blow onto the roadway such as, sand, gravel, or dirt?

• Keep the load uncovered for better visibility.
• Use a close-fitting cover to secure the load.
  Explanation:

  "You must not drive or move any loaded vehicle on the highway if the load is not secure. The load must not be able to drop, shift, leak, or otherwise escape. You must use a close-fitting cover when hauling loads that could fall or blow onto the roadway (e.g., dirt, sand, gravel)."
• Avoid using any covers for flexibility.
• Tie the load loosely to allow for movement.
