U.S. households with more vehicles travel more but use additional vehicles less
Households in the United States with more vehicles not only travel more, but they often put more miles on their most-used (primary) vehicle compared with households with fewer vehicles, according to the Federal Highway Administration's National Household Travel Survey (NHTS). Households with just one vehicle drove an average of about 11,100 miles per year, while households with more than five vehicles traveled a total of about 41,800 miles; each additional vehicle within a household had less average use. About two-thirds of households have either one or two vehicles.
