Which HOS rule changed in December of 2014?

Answer: B — 34-hour restart

The correct answer pertains to the changes made to the 34-hour restart provision in the Hours of Service (HOS) regulations. Before these changes were implemented in December 2014, drivers could use the 34-hour restart without any limitations. However, the new rules introduced specific restrictions aimed at enhancing safety and reducing fatigue among drivers. Under the revised 34-hour restart provision, drivers are now required to include two periods of nighttime rest, specifically between the hours of 1 a.m. and 5 a.m., in their 34-hour reset. This adjustment was made to ensure that drivers are getting enough rest during nighttime hours, which is critical for maintaining alertness and overall road safety. The goal of these modifications was to improve the wellbeing of drivers and reduce the risk of accidents due to driver fatigue. This change reflects a broader trend in the trucking industry aimed at enhancing safety regulations and recognizing the importance of proper rest for those operating commercial vehicles.
