The moving 12-month total of vehicle miles traveled (VMT) in the United States illustrates nationwide trends of growth, flattening, or decline in VMT. VMT in the 12-month period ending in March 2022 matched the 12-month period ending in December 2019, before the start of the COVID-19 pandemic. Total U.S. VMT reached a peak of 3.28 trillion miles in the 12-month period ending in February 2020 but declined steeply the following year. Due to pandemic-related disruptions, the12-month period ending in February 2021 was the lowest point for total 12-month VMT since November 2002.
