According to the article, the shortage is industry wide. The result of what you suggest would be a bidding war for the existing truckers, until the point the bidding has devoured all economic profit. We don't see that happening, clearly.
My hypothesis of implicit or explicit collusion among the dwindling number of trucking firms to drive down wages instead of drawing on supposedly elastic supply manages to explain that, on the other hand. The only other possibility would be an industry wide miscalculation that just happens to look the same as widespread collusion.
