FMCSA Publishes Clarification to the HOS Rules

On Sept. 12, 2019, the Federal Motor Carrier Safety Administration (FMCSA) published in the Federal Register a final rule that amends its hours-of-service (HOS) for CMV drivers to remove provisions requiring that a 34-hour restart include two periods between 1:00 AM – 5:00 AM and limiting use of a restart to once every 168 hours from the code of Federal Regulations.

As you are aware, these provisions through several Congressional Appropriations Bills have been suspended for several years, pending completion of a study that compares this provision with previous restart rules. The study was completed in 2017, in which no safety value was found, therefore voiding the 34-hour restart rules. Even though, these regulations are not in effect they remain in the Federal Code, and this final rule will remove confusion that may exist in the marketplace. 

This final rule takes effect immediately on Sept. 12, 2019.
