The Federal Motor Carrier Safety Administration has concluded data collection for the congressionally-mandated study on the effects of hours-of-service restart regulations.

Following congressional requirements, the study team collected data comparing the five-month work schedules of drivers to assess safety-critical events such as crashes, driver fatigue, and short-term health outcomes of drivers operating under HOS 34-hour restart provisions that were in effect from July 1, 2013 and Dec. 15, 2014. The study looks at the operational, safety, health, and fatigue impacts of two particular provisions of the restart study. 

Drivers from a variety of fleet sizes and operations provided a substantial amount of data during the study period, according to the FMCSA. More than 220 drivers contributed data as they drove their normal routes. The data included over 3,000 driver duty cycles captured by electronic logging devices, over 75,000 driver alertness tests and more than 22,000 days of driver sleep data.

Now that the collection period is over, the agency will analyze the data and work toward completing a final report by the end of the year.

The 34-hour restart provision was suspended in Dec. 2014 as part of a bill signed by President Obama and pushed for by the ATA. The restart suspension was put in place to allow the government to properly evaluate the rule change to determine if it was possibly increasing driver risk.

    This is scary. The Fmcsa new rules are now killing more drivers than ever,CEOs are thinking of either selling or closing because of new Fmcsa rules. The economy is being ran into the ground by the Fmcsa and epa. Why I am so stupid to think that if we were left alone with all this new and just unforced what rules we have and have common sense prevail. But we have a President that has no common sense or belives in the common person. You must vote to change this.

    you blame Obama but he did sign the bill to rescind the restart provisions, and the rest of the up coming rules were long planted before he came into office. Need to blame Ferro for this and the ATA that now seems to have Fox in their pocket. With such a bill highway bill on the table, where the new rules for the FMCSA will reside. This is where things need to change, Transportation regulation should be on its own bill.
