The new Hours of Service rule prohibits driving if more than how many hours have elapsed since the driver's last off-duty period of at least 30 minutes?

Answer: B — Five

The new Hours of Service rule stipulates that a driver may not continue driving if more than five hours have elapsed since their last off-duty period of at least 30 minutes. This regulation is designed to enhance safety by preventing driver fatigue, ensuring that operators of commercial vehicles take necessary breaks to rest. Limiting driving time in this way helps maintain alertness and reduces the risk of accidents associated with tiredness. By specifying a five-hour maximum until a break must be taken, the rule provides a structured approach to managing driving hours and reinforces the importance of regular rest periods during long hauls.
