Caveats

  • Computed by Understand Idaho from Highway Statistics series; it is not a figure the publisher releases.
  • Vehicle miles traveled (VM-2) is an estimate from each state's own travel monitoring program, not a direct count.
  • Traffic fatalities (FI-20) are Fatality Analysis Reporting System (FARS) counts as FHWA republishes them by functional system.
  • Vehicle registrations (MV-1) count registered vehicles, not owners; one business or agency vehicle counts once regardless of drivers.
  • The licensed-drivers table (DL-1C) starts in 2010 in this republication; earlier years are not available through this source.
  • No source table prints a state total for its category breakdown; a state total here is summed from the categories.
  • Puerto Rico appears in the source tables but is excluded here; it is not in this site's geography list.

Inputs: Highway Statistics series.
