Federal regulations in the United States dictate the maximum driving time for commercial truck drivers to prevent accidents caused by driver fatigue. These regulations, known as the Hours-of-Service (HOS) rules, limit driving time to 11 hours after 10 consecutive hours off duty. Furthermore, drivers cannot drive beyond the 14th hour after coming on duty following 10 consecutive hours off duty. There are also stipulations regarding weekly cumulative driving limits.
These limitations are crucial for maintaining highway safety and protecting both truck drivers and the motoring public. Driver fatigue is a recognized contributing factor in numerous accidents, and the HOS regulations aim to mitigate this risk. Historically, these regulations have evolved based on research, technological advancements, and changing industry needs. The current rules represent a balance between allowing drivers to earn a living and ensuring adequate rest to maintain safe operating conditions on the roads.
