Why is re-checking securement shortly after entering a bumpy road or after hard braking events good practice, beyond scheduled checks?
- A.Checks are only legal at scheduled intervals
- B.Shocks and vibration are what loosen tiedowns and shift loads, so a check right after severe conditions catches movement while it is still correctable
- C.Loads tighten themselves on rough roads
- D.Hard braking never affects securement
Correct answer
B. Shocks and vibration are what loosen tiedowns and shift loads, so a check right after severe conditions catches movement while it is still correctable
Why
The scheduled intervals are a minimum rhythm, not the whole duty. Any event that works the load, rough pavement, a hard stop, a steep grade, is a reason to find a safe place and verify that nothing has moved or loosened.
