The increasing use of double trailer trucks on the nation's highways has raised concerns about their safety, especially as compared to the more common single-trailer trucks. The purpose of this study was to examine the accident rate of double-trailer, often known as double-bottom trucks as compared to single-trailer trucks on the Snoqualmie Pass portion of Interstate-90. Unfortunately, accurate data concerning truck accidents and truck volumes could not be developed from current data sources.
