KEY: R = revised.
a Beginning in 1998, the Federal Highway Administration (FHWA) used
the Census Bureau's 1997 Vehicle Inventory and Use Survey (VIUS) for
its baseline estimate of single-unit 2-axle 6-tire or more trucks. Prior to
1998, the FHWA used the Census Bureau's 1992 Transportation Inventory and
Use Survey (TIUS) for its baseline estimates. Therefore, post-1997 data
may not be comparable to 1997 and earlier years.
NOTE
In 1995, the U.S. Department of Transportation, Federal Highway Administration
revised its vehicle categories beginning with 1993 data to include passenger
cars, other 2-axle 4-tire vehicles, single-unit 2-axle 6-tire or more trucks,
and combination trucks. Single-unit 2-axle 6-tire or more trucks are on a single
frame with at least 2 axles and 6 tires. Pre-1993 data have been reassigned
to the most appropriate category.
