Hours-of-service rules safety impacts : 2010 analysis. Submitted to the American Trucking Associations.

This research utilized motor carrier safety performance data from 2004 and 2009 to examine HOS safety impacts on the trucking industry. The 2004 dataset is from an earlier ATRI study, Safety Impacts of the New Hours-of-Service (March 2006). The 2009 safety performance data resulted from a data collection effort initiated by ATRI in March 2010. This survey effort utilized specific survey questions captured from the earlier ATRI study to ensure that cross-comparisons could be completed. Additional questions were also included in the March 2010 data survey to solicit information on use of the 11-hour driving and 34-hour restart provisions. (Author/publisher)
