Hours of Service of Drivers

Summary: On January 24, 2005, the Federal Motor Carrier Safety Administration (FMCSA) published in the Federal Register (70 FR 3339) a Notice of Proposed Rulemaking (NPRM) regarding hours of service of commercial motor vehicle drivers. In that NPRM, FMCSA announced it is reviewing and reconsidering the regulations on hours of service of drivers published on April 28, 2003, and amended on September 30, 2003. In the docket to this January 24, 2005, NPRM, FMCSA re-filed the same Regulatory Impact Analysis (RIA), or comprehensive analysis of economic benefits and costs of the proposed rule, as was filed in the docket for the April 2003 final rule. However, effective January 1, 2005, the Office of Management and Budget (OMB) imposed new analytical requirements on Federal agencies regarding the preparation of RIAs for economically significant rulemakings. These new requirements include an uncertainty analysis, or an analysis of the ``degree of uncertainty'' associated with key variables used in the analysis (i.e., the percent of all truck-related crashes where commercial driver fatigue is a factor) and how significantly that uncertainty affects the benefit and cost estimates derived. A primary value of uncertainty analysis is its ability to highlight those key variables where additional data collection (to reduce uncertainty) would most benefit the decision making process. Additionally, OMB now requires a cost-effectiveness analysis for those rulemakings where improved public health and safety are the primary benefits. The cost effectiveness of a regulatory action is typically measured as a ratio of the change in costs occasioned by the action compared to its positive results (i.e., lives saved). A primary value of cost-effectiveness analysis is its ability to identify regulatory options that achieve the most effective use of the resources available without requiring monetization of all of the relevant benefits or costs. In light of these new requirements, FMCSA has prepared an addendum to the original RIA containing the two supplemental analyses and has made it available in Docket FMCSA-2004- 19608.
