The rules are 11/14/70. 11 Hours driving maximum per day, 14 hours on duty maximum per day, and 70 hours maximum per rolling 8 day period (or 60 hours per rolling 7 day period). Between driving periods, you must take 8 hours + 2 hours (most drivers just do a 10 hour rest period) in the sleeper berth. If you take 34 hours (knows as a reset) off duty, your rolling HOS clock resets to 0 and you can drive a full 70 again. Being awake for me, and functional for 14-18 hours continuous is never a problem for me, but when I drove I avoided being in a urban area when I was that tired - I'd stop short, sleep outside of town, and head in in the morning to drop the load at the receiver usually.
