Annual Miles Driven
Amidst an economic recovery, the prevalence of fuel efficient vehicles and cheap gasoline prices, the total
number of miles driven on U.S. roads in 2016 increased slightly from last year. This is the fourth consecutive
year since 2012 of increased mileage on U.S. roads. For calendar year 2016, the total number of vehicle
miles driven was 3.2 trillion miles, an increase of 2.8 percent over the previous year’s total of 3.1 trillion miles.
Americans in recent years are driving more miles than they did in 2007 when miles driven reached three trillion
miles. Given the fluctuating
cost of gasoline, the
anticipated retirement of the
baby boomer workforce and
the uncertainty in the global
economy, it is unknown how
miles driven will trend in the
coming years.
While miles driven is on the
uptick recently, the steady
increase in miles driven began
in 1990. From a historical
perspective, the number of
miles driven on all U.S. roads
has increased at a 1.6 percent
compounded annual growth
rate (CAGR) since 1990.

These indicators suggest continued reliance on private vehicle usage in the years ahead, although high gasoline
prices tend to have a negative impact on total miles driven.
