- ATo provide additional tie-down points for lighter cargo.
- BTo improve the aerodynamics of the truck and trailer combination.
- CTo protect the driver and cab from shifting cargo during a sudden stop.
- DTo serve as a mounting point for extra lights and air horns.
Show answer & explanationAnswer & explanation
Correct answer: C. To protect the driver and cab from shifting cargo during a sudden stop.
Header boards, or 'headache racks,' are designed safety devices. Their primary purpose is to protect the truck's cab and, most importantly, the driver from cargo that might shift forward during an abrupt stop or collision.
Why the other options are wrong
- A. While some may have tie-down points, it's not their primary function.
- B. They generally increase air resistance rather than improve aerodynamics.
- D. Some accessories may be mounted, but this is secondary to their safety function.
Header Board (Headache Rack)
A protective barrier at the front of a flatbed trailer, behind the cab, to prevent cargo from shifting forward.
- Protects driver and cab.
- Essential safety feature for flatbeds.
- Prevents injury from sudden stops.
Memory trick: A headache rack for a shifting attack, keeps the driver safe in the back.
