Hours of Service Rules Explained: The 2026 Driver's Guide

Hours of service (HOS) rules generate more confusion — and more violations — than almost any other area of FMCSA regulation. Partly that’s because the rules involve interlocking time limits that have to be tracked simultaneously. Partly it’s because drivers and carriers sometimes misremember older rule versions or misread the exceptions. And partly it’s because the regulatory landscape has been moving, with FMCSA running flexibility pilots that haven’t become permanent rules.

This guide cuts through the noise. I’ll walk you through every current HOS requirement for property-carrying commercial motor vehicles, give you practical examples of how a real day looks under the rules, and flag the misunderstanding I see causing the most violations in the field.

Who These Rules Apply To

The HOS rules covered here apply to property-carrying CMV drivers subject to FMCSA regulation — generally drivers operating vehicles over 10,001 pounds GVWR in interstate commerce, or intrastate operations in states that have adopted the federal rules. Passenger-carrying rules differ and are not covered in this guide. Certain short-haul and agricultural exemptions also exist; those are beyond the scope of this post.

If you’re a carrier or owner-operator unsure whether your operations are fully subject to these rules, our services page outlines how LAN can help you map your regulatory exposure.

The Core Property-Carrying HOS Framework

There are four interlocking limits. You must comply with all of them simultaneously — they do not operate independently.

The 11-Hour Driving Limit

A property-carrying driver may drive a maximum of 11 hours after coming off 10 consecutive hours off duty. Once you’ve used your 11 hours of driving, you’re done driving until you’ve reset with 10 consecutive hours off.

Key point: This is a driving limit, not an on-duty limit. You can continue performing other on-duty work after your 11 hours of driving are exhausted, subject to the 14-hour rule below.

The 14-Hour On-Duty Window

Once a driver comes on duty after at least 10 consecutive hours off, a 14-hour clock starts. The driver may not drive after the 14th hour from that point — regardless of how many driving hours remain. If the driver has only used 9 hours of driving but the 14-hour window has closed, driving stops.

The 14-hour window does not pause for breaks, fuel stops, or on-duty-not-driving time. It runs continuously from the moment you come on duty.

Practical example: A driver starts duty at 6:00 a.m. The 14-hour window closes at 8:00 p.m. No matter what, that driver cannot drive after 8:00 p.m., even if they only drove 7 hours during the day.

The 10-Hour Off-Duty Reset

Before a driver can start a new 11/14 cycle, they must take 10 consecutive hours off duty. This resets both the 11-hour driving limit and the 14-hour window.

The 30-Minute Break Requirement

A driver may not drive beyond 8 cumulative hours of driving time since the last break of at least 30 minutes. That break can be satisfied by a period of off-duty time, sleeper berth time, or on-duty-not-driving time — it does not have to be off the clock.

Common misread: The 30-minute break restarts the 8-hour driving counter. You are not required to take a new 30-minute break every 8 hours from the start of shift — it’s 8 hours of cumulative driving since the last qualifying break.

Practical example: A driver starts at 6:00 a.m. and drives continuously. By 2:00 p.m. they’ve driven 8 hours. They must take at least a 30-minute break before driving again. After the break, their 8-hour counter resets.

The Weekly Limits: 60/70-Hour Rules

In addition to the daily limits, drivers are subject to a rolling weekly cap.

• 60-hour/7-day rule: A driver may not drive after reaching 60 hours on duty in any 7 consecutive days.
• 70-hour/8-day rule: A driver may not drive after reaching 70 hours on duty in any 8 consecutive days.

Which rule applies depends on whether your carrier operates commercial vehicles every day of the week. If the carrier does not operate every day, the 60/7 rule applies. If the carrier operates every day, the carrier may use the 70/8 rule instead.

The 34-hour restart: A driver who has exceeded or is approaching the weekly limit can restart the 7- or 8-day clock by taking at least 34 consecutive hours off duty. After that restart, the driver may begin a fresh weekly calculation.

Sleeper Berth Splits: How They Work

Drivers using a sleeper berth have an additional option for managing their 10-hour off-duty requirement. The rules allow the required off-duty time to be split into two periods, as long as:

• Neither period is less than 2 hours
• One of the two periods is at least 7 hours spent in the sleeper berth
• Together, the two periods total at least 10 hours

The most common split is 8 hours in the sleeper berth + 2 hours off duty (or vice versa). Another valid combination is 7 hours in the sleeper berth + 3 hours off duty.

How the 14-hour window interacts with splits: When using a sleeper berth split, the qualifying sleeper berth period pauses the 14-hour window. This is one of the more complex aspects of HOS, and one reason ELD configurations matter — the system needs to be set up to correctly account for split-berth pausing.

Team drivers operating with a co-driver in a sleeper berth can use the sleeper berth provisions to maximize continuous operation. The driver in the berth accumulates off-duty time while the other driver operates the vehicle.

Electronic Logging Devices (ELDs)

Most carriers operating CMVs subject to the ELD mandate are required to track HOS via an FMCSA-registered electronic logging device. ELDs automate much of the HOS recordkeeping — but they do not think for drivers. Drivers still need to understand the rules to catch ELD configuration errors, interpret their logs correctly, and avoid violations from on-duty status errors.

ELD mandate exceptions exist for certain short-haul drivers, drivers of vehicles manufactured before model year 2000, and drivers operating under specific exemptions. If you’re unsure whether you’re exempt, don’t assume — the civil penalties for non-compliance are significant.

The FMCSA Flexibility Pilots: What They Are and What They Are Not

FMCSA has been running pilot programs testing added HOS flexibility — including a Split Duty Period pause concept and additional split options beyond the existing sleeper berth splits. These pilots are designed to gather data on whether expanded flexibility can be granted without compromising safety.

These pilots are not permanent rules. Participation is limited, structured, and monitored. A driver who has not been formally enrolled in an approved pilot program cannot operate under pilot conditions. Until FMCSA completes the pilot data analysis and issues a final rule, the standard HOS framework described in this guide is what applies to the overwhelming majority of operations.

Watch for FMCSA rulemaking activity. If and when pilots become permanent rules, LAN will cover those changes directly. In the meantime, do not rely on pilot descriptions you’ve seen circulated informally — verify with official FMCSA sources or consult with a compliance professional.

A Full Driving Day: Practical Walkthrough

Here is how a compliant day looks for a solo property-carrying driver:

This driver hit the 11-hour driving limit before the 14-hour window closed — a clean, compliant day. Notice the 45-minute break at midday reset the 8-hour driving counter, so the driver never bumped against the 30-minute break requirement.

My Opinion: The HOS Misunderstanding That Causes the Most Violations

Here it is: drivers and carriers treating the 14-hour window as if breaks pause it.

I’ve seen this understanding embedded in dispatch culture at carriers, passed from one driver to the next like it’s fact. “If you stop and take a break, your 14 hours pause.” It does not. The 14-hour window runs from the moment you come on duty until it closes 14 hours later, period. Breaks, meals, fuel stops, and waiting time do not slow the clock.

This misunderstanding leads drivers to believe they have more usable driving time than they actually do. When the ELD flags the violation or a roadside officer checks the logs, the surprise is genuine — and the violation is real. Carriers who train drivers correctly on the non-pausable nature of the 14-hour window have noticeably fewer HOS violations in their CSA data.

If your safety training program isn’t explicitly addressing this point, it should be.

Staying Compliant: Practical Steps for Carriers and Owner-Operators

• Train drivers on all four limits — the 11-hour driving limit, the 14-hour window, the 10-hour reset, and the 30-minute break — as interlocking rules, not independent ones
• Verify your ELD configurations against the rules, particularly for sleeper berth split pausing
• Review your HOS violation data in SMS regularly — recurring HOS violations in a particular driver or terminal point to a training or dispatch culture problem
• Owner-operators: your ELD, your logs, your violation. Know the rules as well as any fleet safety manager

Frequently Asked Questions

Q: Can a driver extend the 14-hour window by taking a break? A: No. The 14-hour window runs continuously from the time the driver first comes on duty after the required off-duty period. Breaks, meals, and non-driving on-duty time do not pause the clock.

Q: Does the 30-minute break have to be off-duty time? A: No. The break can be satisfied by off-duty time, sleeper berth time, or on-duty-not-driving time — as long as it is an uninterrupted period of at least 30 minutes with no driving.

Q: What is the difference between the 60/7 and 70/8 rules? A: The 60/7 rule applies to carriers that do not operate commercial vehicles every day of the week. The 70/8 rule is available to carriers that operate every day. Both caps are on total on-duty hours in the rolling window — not just driving hours.

Q: How does a 34-hour restart work? A: A driver who takes at least 34 consecutive hours off duty resets their 7- or 8-day rolling total to zero. After the restart, the driver begins a fresh weekly calculation.

Q: What are the penalties for HOS violations? A: Civil penalties for HOS violations can be substantial, and drivers can be placed out of service at roadside for certain violations. Repeated or egregious violations affect CSA scores and can trigger FMCSA interventions.

Disclaimer: HOS rules are subject to change through rulemaking and pilot programs. Verify current FMCSA requirements before applying these rules to your operations, or consult Logistics Assistance Now for guidance specific to your situation.
