⏳

14 hrs

Max on-duty time after 10 off. Includes all work — not just driving.

💡 Once 14 hours start ticking, you can't drive after they expire — even if you have driving time left.

🛣️

11 hrs

Max driving time after 10 consecutive hours off.

💡 You must stop driving at 11 hours, even if within your 14-hour window.

☕

30 min

Required after 8 cumulative hours of driving. Off-duty or sleeper berth.

💡 Loading/unloading time won't count toward your break — must be truly off-duty or in the sleeper.

📅

60 / 70 hrs

60 in 7 days (6-day ops) or 70 in 8 days (7-day ops).

💡 34-hour restart resets your 7/8-day clock. Must include two 1am-5am periods.

🔄

34 hrs

Resets 7/8-day clock. Must include 2 periods of 1am-5am.

💡 Can only be used once per 168 hours (one week). Plan your reset days carefully.

🛌

7/3 or 8/2

Split 10 hours: 7 in sleeper + 3 off-duty, or 8+2.

💡 The sleeper period pauses your 14-hour clock — extends your workday!

Getting caught with these can put you OUT OF SERVICE and result in fines up to $16,000:
