On the National Safety Code, if there's going to be a national code, there needs to be national oversight, national enforcement and a national audit. Without all four pieces of that, it's not going to work.
On safety, if people are out driving a big truck fully loaded at 80,000 pounds with limited training, it stands to reason they're not going to be as safe as the alternative: someone who's properly trained and properly prepared to do that type of work. Its just common sense to me.
