7.5 Observations on Changes between 1992 and 1997 for Particular
Truck Configurations and Body Types
7.5.1 Changes in Trailer Widths by 1997
The adoption of the 102 inch width trailer afforded by the 1982 STAA by different body
types/truck configurations is summarized below and in Table 7.5.1-1. Figure 7.5.1-1 compares,
for 1987, 1992 and 1997, the percentage of specific truck configuration/body type combinations
that have trailer widths equal to or greater than 102 inches. Figure 7.5.1-2 compares the regional
percent of 3S2s with trailer widths of 102 inches or more for certain body types for 1997.
