How much of the goods transported between Canada and the U.S. by truck is accounted for by NAFTA?

Answer: B — 47.1%

The correct answer highlights that 47.1% of the goods transported between Canada and the U.S. by truck are accounted for by NAFTA. This statistic reflects the significant impact and volume of trade facilitated by the North American Free Trade Agreement. NAFTA, which went into effect in 1994, aimed to eliminate trade barriers between the U.S., Canada, and Mexico, leading to a substantial increase in cross-border trade and economic integration. The agreement has enabled easier access to markets and reduced tariffs, making it more economically viable for businesses to transport goods between these countries. This percentage indicates a strong reliance on the trade framework established by NAFTA, showing how integral it is to the trucking and logistics sectors. In understanding this statistic, it is important to recognize how international trade agreements can shape industry practices, influence economic relationships, and affect supply chains across borders.
