Start Preamble


Federal Motor Carrier Safety Administration (FMCSA), DOT.


Notice of proposed rulemaking; extension of comment period.


The Federal Motor Carrier Safety Administration (FMCSA) extends the comment period for its August 22, 2019 notice of proposed rulemaking (NPRM) to amend its hours-of-service (HOS) rules. FMCSA received requests for an extension to the comment period from the American Trucking Associations, the Commercial Vehicle Safety Alliance, and the International Brotherhood of Teamsters. The Agency believes it is appropriate to extend the comment period to provide interested parties additional time to submit their responses to the NPRM. Therefore, the Agency extends the deadline for the submission of comments until October 21, 2019.


The comment period for the NPRM published August 22, 2019 at 84 FR 44190, is extended to October 21, 2019.

II. Background

The August 2019 NPRM requested comment on five topics. First, it proposed extending the maximum duty period allowed under the short-haul exception available to certain commercial motor vehicle (CMV) drivers from 12 hours to 14 hours. It also proposed extending the maximum radius of the short-haul exception from 100 to 150 air miles. Second, the proposal would extend the maximum driving window under adverse driving conditions by up to 2 hours. Third, the Agency proposed to allow the 30-minute break to be taken while the driver remains on duty and to require the break only after 8 hours of driving (instead of 8 hours after coming on duty) without a 30-minute non-driving period. Fourth, the Agency proposed to allow drivers who use sleeper berths to take their required off-duty time in two periods, one of at least 7 consecutive hours in the berth, and the other (of at least 2 hours) either in or out of the berth. The total of these two periods must be a minimum of 10 hours. Neither time period would count against the maximum 14-hour driving window. Fifth, FMCSA proposed to add a new option allowing one off-duty break of at least 30 minutes, but not more than 3 hours, to extend the 14-hour driving window by the length of the break, provided drivers take at least 10 consecutive hours off duty at the end of the work shift.

The comment period for the NPRM was set to expire on October 7, 2019. FMCSA received the requests to extend the comment period from the American Trucking Associations (ATA), the Commercial Vehicle Safety Alliance (CVSA), and the International Brotherhood of Teamsters (IBT). All 3 requests are available in the docket.[1]

ATA requested a 30-day extension of the comment period, stating that the additional time was needed to coordinate with and gather information from members and provide a more useful response to the detailed questions posed in the NPRM. ATA said that it was holding a relevant meeting on October 5-8.

Both CVSA and IBT requested a 45-day extension of the comment period. CVSA stated that the original 45-day period did not allow enough time to prepare and approve comments on such a complicated and important issue. IBT requested that the docket remain open until November 21, 2019, stating that the additional time was needed to effectively develop responses to the questions that FMCSA asked in the NPRM.

Additionally, FMCSA added to the docket additional details regarding its review of the 2011 Blanco Study concerning the change in safety-critical event reduction based on break type.[2]
