When did FMCSA publish a new Final Rule on HOS rules?

Answer: B — 2011

The Federal Motor Carrier Safety Administration (FMCSA) published a new Final Rule on Hours of Service (HOS) rules in 2011. This update was significant as it introduced changes aimed at enhancing safety by preventing driver fatigue. The revisions included regulations that established limits on driving time, mandatory rest breaks, and required a minimum off-duty time between shifts for commercial drivers. These changes were intended to provide clearer guidelines for drivers and carriers, thereby improving the overall safety in the trucking industry. The decision to implement these new rules was based on research and data showing the correlation between driver fatigue and crash risk, making it a pivotal development for transportation safety.
