Hours of Service (HOS) Rules Explained
Updated June 2026
How many hours can you still drive?
Hours-of-service (HOS) rules limit how long you can drive to fight fatigue. Here are the main federal rules for property-carrying drivers, in plain terms.
The 11-hour driving limit
After 10 consecutive hours off duty, you may drive up to 11 hours.
The 14-hour window
You cannot drive beyond the 14th consecutive hour after coming on duty. Breaks and meals don't stop this clock — once 14 hours pass, you're done driving until another 10-hour break, even if you haven't hit 11 driving hours.
The 30-minute break
You must take a 30-minute break after 8 cumulative hours of driving without at least a 30-minute break. It can be off-duty, sleeper, or on-duty not driving.
The 60/70-hour limit
You can't drive after 60 hours on duty in 7 days, or 70 hours in 8 days (which one applies depends on whether your carrier runs every day). This is a rolling total.
The 34-hour restart
Taking 34 consecutive hours off duty resets your 60/70-hour clock back to zero.
Some flexibility
The sleeper-berth provision, adverse driving conditions, and the short-haul exception can adjust these in specific cases. Your ELD tracks it all — but knowing the rules keeps you legal. Use the calculator below to check how much driving time you have left right now.

Frequently asked questions
Does taking a break extend my 14-hour window?
No. Off-duty breaks generally do not pause the 14-hour driving window (the sleeper-berth split is a limited exception).
What resets the 70-hour clock?
A 34-hour restart — 34 consecutive hours off duty — sets your weekly on-duty total back to zero.
