Which scenario would qualify as a valid 34-hour restart under HOS rules?

• A. Driving continuously for 34 hours
• B. Taking a 24-hour break
• C. Off-duty for 34 hours in a row
• D. Off-duty only working but not driving

Answer: (C)

A 34-hour restart is a block of time off duty that resets the hours clock. To qualify, you must be off duty for 34 consecutive hours, with no driving or on-duty work during that period. Sleeper berth time can count toward the off-duty time, but the entire stretch must be off duty. This is why being off duty for 34 hours in a row is the valid restart—the other scenarios don’t meet the requirement: driving continuously for 34 hours isn’t allowed, a 24-hour break isn’t long enough to qualify, and being off duty but still working or not off duty wouldn’t count toward the restart.
