In the 1990s, by what percentage did vehicle miles traveled (VMT) grow?

Answer: D — 26%

In the 1990s, vehicle miles traveled (VMT) experienced significant growth, reflecting trends in transportation, economic expansion, and population increases during that decade. The correct percentage of 26% denotes a considerable rise in the amount of driving that occurred across the United States, showcasing not only the reliance on vehicles for personal and commercial travel but also the expansion of suburban areas and infrastructure development that facilitated increased road use. This increase in VMT is indicative of broader societal trends, including more vehicles on the road, greater distances being traveled, and changes in land use patterns. By understanding that VMT grew by this percentage, one can appreciate how transportation planning and policies may adapt to accommodate rising demand for road usage and the importance of addressing related issues, such as traffic congestion and environmental impacts.
