What is the maximum number of on-duty hours allowed within a Cycle 1 workweek?

• A. 50 hours
• B. 70 hours
• C. 90 hours
• D. 120 hours

Answer: (B)

In a Cycle 1 workweek, the maximum number of on-duty hours allowed is 70 hours. This regulation is set to ensure that drivers have adequate rest, promoting safety on the road and reducing the risk of fatigue-related accidents. The 70-hour limit applies over a seven-day period and is a critical guideline within the framework of Hours of Service (HOS) regulations, which govern how long drivers can operate commercial motor vehicles.

Given this context, it’s important to understand that while some other options might represent hours that are more than what is permitted, they do not comply with regulatory safety standards. Maintaining a balance between driving time and rest is essential for both driver health and public safety on roadways.
