11-Hour Rule Guide

Who This Applies To

• Property-carrying CMV drivers tracking the daily driving limit and planning when they need to stop for the required off-duty reset.
• Dispatchers scheduling pickups and deliveries around the driver's remaining driving hours in the current shift.
• Carriers reviewing ELD records for 11-hour rule violations or coaching drivers who are consistently using maximum driving time.
• New CDL holders who understand the 11-hour limit exists but aren't clear on exactly what counts as driving time versus other on-duty activity.

What To Verify

• That the driver has completed 10 consecutive hours off duty before the new driving clock begins. The 11-hour driving limit resets only after a qualifying off-duty period — not after a restart, a sleeper berth split, or a short rest break.
• That all time recorded as 'driving' in the ELD accurately reflects actual driving. Time spent waiting at a shipper while the vehicle is running but not moving may or may not count as driving depending on how it's recorded — verify with the current FMCSA guidance.
• The current eCFR Part 395 text if a sleeper berth split is being used. The split provision modifies how the 14-hour window is calculated but does not change the total amount of driving time available.
• Whether any adverse driving conditions exception applies, which allows up to 2 additional hours of driving. The conditions must have been unforeseeable at the start of the shift — foreseeable bad weather doesn't qualify.

Step-by-Step Overview

1. Track driving time separately from total on-duty time. Being on duty but not driving — loading, fueling, waiting — counts against the 14-hour window but does not count against the 11-hour driving limit.
2. Plan rest before approaching the 11-hour limit, not at it. Stopping with 30 minutes of driving time remaining is a better operational practice than trying to complete a delivery at the limit's edge.
3. When reviewing ELD records, check that the driving total for each 24-hour period doesn't exceed 11 hours from the point the driver came on duty after a qualifying 10-hour rest.
4. If the adverse driving conditions exception is used, annotate the ELD log with the specific conditions encountered. The annotation supports the exception claim during a roadside inspection.
5. After any shift using maximum driving time, confirm the off-duty period is at least 10 consecutive hours before the next on-duty period begins.

Common Mistakes

• Counting on-duty not-driving time as though it extends the driving window. On-duty not-driving time eats into the 14-hour window and may reduce the available shift length, but it doesn't reduce the 11-hour driving cap directly.
• Assuming a sleeper berth split resets the 11-hour driving limit in the same way it modifies the 14-hour window calculation. The split provision deals with window calculation, not driving-hours accumulation.
• Applying the adverse driving conditions exception to foreseeable conditions. A driver who regularly runs a route with known seasonal traffic or predictable weather cannot use the exception for those conditions — it applies to genuinely unexpected events.
• Not annotating the ELD log when driving conditions justify an exception. Without documentation, an inspector has no way to evaluate the claim — and the driver's verbal explanation carries less weight than a contemporaneous log annotation.
• Logging time as off-duty during a rest break that doesn't meet the 10-hour consecutive threshold. A short off-duty break within a shift doesn't reset the 11-hour clock.
