Availability of Supplemental Documents

For a full background on this rulemaking, please see the preamble to the NPRM (75 FR 82170, December 29, 2010). The docket (FMCSA-2004-19608) contains all of the background information for this rulemaking, including comments. FMCSA has placed these four research reports in the docket:

  • Blanco, M., Hanowski, R., Olson, R., Morgan, J., Soccolich, S., Wu, S.C., and Guo, F., “The Impact of Driving, Non-Driving Work, and Rest Breaks on Driving Performance in Commercial Motor Vehicle Operations,” FMCSA, April 2011.
  • Jovanis, J.P., Wu, K.F., and Chen, C., “Hours of Service and Driver Fatigue—Driver Characteristics Research,” FMCSA, April 2011.
  • Sando, T., Angel, M., Mtoi, E., and Moses, R., “Analysis of the Relationship Between Operator Cumulative Driving Hours and Involvement in Preventable Collisions,” Transportation Research Board of the National Academies' 2011 90th Annual Meeting, Paper No.: 11-4165, November 2010.
  • Sando, T., Mtoi, E., and Moses, R., “Potential Causes Of Driver Fatigue: A Study On Transit Bus Operators In Florida,” Transportation Research Board of the National Academies' 2011 90th Annual Meeting, Paper No.: 11-3398, November 2010.

The two Sando, et al., reports discuss research similar to that which the Florida Department of Transportation Transit Office submitted to the docket on March 4, 2011 (docket item 23834: Sando, T., Moses, R., Angel, M., and Mtoi, E., “Safety Implications of Transit Operator Schedule Policies,” University of North Florida and Florida Department of Transportation, October 2010). The two additional reports by Sando and his colleagues were published by the Transportation Research Board of the National Academies for its 2011 90th Annual Meeting. They were provided to 2011 Annual Meeting participants on digital video disk and are available for downloading at

FMCSA may consider these four reports in its rulemaking and invites comment on their relevance to the NPRM.

FMCSA is reopening the comment period only for comments on these documents and their relationship to the proposed HOS regulations. Comments unrelated to the studies and/or to their relationship to the NPRM will not be evaluated.

Rulemaking Schedule

FMCSA advises the public of an adjustment to the rulemaking schedule agreed to in litigation before the U.S. Court of Appeals for the District of Columbia Circuit (Case No. 09-1094). Pursuant to an October 26, 2009, agreement between Public Citizen, et al. (Petitioners), and FMCSA, the Agency was to publish a final rule within 21 months of

the date of the settlement agreement. FMCSA will receive and analyze all comments to this notice before it completes its work on a final rule, however. This extra comment period will require additional time that was not envisioned in 2009, and thus the Agency will be unable to publish a final rule by July 26, 2011. FMCSA has advised Petitioners of this delay to the rulemaking schedule.
