Yep, and the shortage of qualified, competent truck drivers isn't helping matters either.
From reading the article about the incident, it sounds more like it was a couple of novice riders on rented bikes that caused it. Both riders were tourists from Italy, both riding new Harley FLTRXes. Traffic slowed ahead of them, one lost control and went down, other crashed into him, and the semi ran them both over. Sad, but doesn't sound like it was the fault of the truck driver at all.
