1990 to 2016
U.S. DOT, FHWA, provides data separately for passenger car and motorcycle in its annual Highway Statistics series. However, the 1995 summary report provides updated data for Passenger car and Motocycle combined. Passenger car figures in this statistic were computed by U.S. DOT, Bureau of Transportation Statistics, by subtracting the most current motorcycle figures from the aggregate Passenger car and Motorcycle figures. 1960 and 1965: motorcycle data are included in passenger car data.
** In July 1997, the FHWA published revised vehicle-miles data for the highway modes for many years. The major change reflected the reassignment of some vehicles from the passenger car category to the other 2-axle 4-tire vehicle category. This category was calculated prior to rounding.
