By Matt Binder, The Associated PressThe North American trucking industry was built on a set of rules that put a lot of emphasis on safety.
The rules were designed to protect the public from accidents, and they also provided a system for securing cargo, keeping it from leaking, and providing a safe and secure way to move goods around the world.
But the rules have been evolving as the industry has evolved, and the rules are becoming less robust.
In a new book, “A Changing World: The Story of North American Logistics,” journalist and author Peter DeGraff tells the story of what happened in the past 20 years.
In his book, DeGraFF says that North American trucks were built to operate under a set set of regulations that allowed for a lot more flexibility than they are today.
The trucking rules were originally created to prevent cargo spills, such as the one that led to the deaths of more than 20 people in the 1980s, he says.
But in recent years, the rules in many countries have been loosened and replaced with more stringent requirements.
He says this has been an unintended consequence of the global financial crisis.
The U.S. has a long history of trucking accidents, especially in the wake of World War II, when there was an explosion at a Chicago, Illinois, port.
DeGraef says that the U.K. and the U of T in Canada are two of the worst offenders, because of lax safety standards and the way they are managed.
The changes in North American shipping are part of a larger trend that has occurred in the trucking sector.
In recent years the industry is moving away from a reliance on a fixed set of operating rules.
DeGraff says that a lot has changed over the last 20 years, but the underlying rules have not changed.
They are based on the same principles, he said.
