Why should you never go under a trailer unless it is properly supported?
- A.It is only a company rule, not a safety issue
- B.If the landing gear fails or the trailer is not supported, the trailer can fall and crush you
- C.Trailers are light at the front
- D.The fifth wheel alone always holds it
Correct answer
B. If the landing gear fails or the trailer is not supported, the trailer can fall and crush you
Why
A trailer front weighs tons, and gear legs can sink, collapse, or be knocked. Staying out from under an unsupported trailer removes you from the fall zone.
