- B.To make unloading faster
- C.To improve airflow through the trailer
- D.It is only a cosmetic practice
Correct answer
A. To keep the load from shifting forward under hard braking or in a crash

In a sudden stop, an unblocked load keeps moving forward with enormous force and can crush the cab area. Blocking and bracing give the tiedowns help exactly where the forces are greatest.
