34-Hour Reset Calculator (34-hour restart)

A live clock from right now: when your 60/70-hour cycle clears, and the earlier point where you are allowed to drive. Enter your cycle limit and hours used to see what the reset actually returns. Nothing is uploaded — it keeps running offline.

Two clocks, not one. You may drive again after 10 consecutive hours off duty. The 34-hour reset only clears the 60/70-hour weekly cycle. If you still have cycle hours left, you do not need a reset — use the split sleeper calculator or the recap calculator instead.

What the clock is counting

49 CFR 395.3(c): a property-carrying driver restarts the 60-hour/7-day or 70-hour/8-day calculation after 34 or more consecutive hours off duty. It is elapsed time, so a daylight-saving change does not shorten or lengthen it. Drivers say "reset", the regulation says "restart" — same thing.

MarkWhat it gets you
10 consecutive hours offAn 11-hour driving limit and a fresh 14-hour window — this is what "I can drive again" means.
34 consecutive hours offThe 60/70 cycle starts over at that point; hours before it stop counting.
Recap (no time off)Older days roll out of the 7/8-day window on their own — slower than a reset.

What counts, and what breaks it

The old "two periods between 1 a.m. and 5 a.m." requirement is gone — suspended by Congress, removed by the 2020 hours-of-service rule. Ignore apps and blog posts that still plan around it.
