The National Highway System comprises what percentage of the nation's roads?

The National Highway System (NHS) is a crucial network designed to facilitate efficient transportation across the country. It accounts for approximately 4.1% of the total roadways in the United States. This system includes interstates, strategically important highways, and roads that connect major cities and regions, thereby supporting vital economic activity and efficient movement of goods and people.

Understanding this percentage is important because it highlights the concentrated value of this limited portion of roads, which manage a significant share of national traffic, including freight movement. Knowledge of the NHS also emphasizes the importance placed on maintaining and improving these roads to ensure the smooth operation of the nation's transportation infrastructure. The other options present percentages that misrepresent the actual scope of the NHS, making it essential for anyone studying trucking or transportation logistics to be aware of the accurate figure.
