Ankur87 and The Iceman have nailed it.
From cause and effect perspective, the conclusion states:
Cause: Increase usage of triple trailer trucks -> Effect: Reduced highway deaths
To weaken the conclusion, we need to show that its not the triple trailer trucks that would reduce the deaths, instead the reason / cause is something else. Answer choice B provides this reason (its the not the trucks but the exp drivers that would help in reducing deaths)
