HOS Rules 2026: The Complete Hours of Service Breakdown
The Hours of Service regulations control how long you can drive, when you must rest, and how your weekly clock resets. Getting them wrong means out-of-service orders, fines up to $16,000 per violation, and CSA score damage that follows you for three years. This guide covers every current HOS rule, what changed heading into 2026, and how to stay compliant without leaving money on the table.

O TruckingHOS Rules 2026: Complete Breakdown
The 5 Core HOS Rules Every Driver Must Know
Federal Hours of Service regulations under 49 CFR Part 395 are built on five interlocking rules. Each rule limits a different dimension of your driving time: how many consecutive hours you can drive, how long your on-duty window lasts, when you need a break, how many total hours you can work in a week, and how to reset that weekly clock. Violating any single rule triggers an out-of-service order even if you are compliant with every other rule.
1. The 11-Hour Driving Limit
You may drive a maximum of 11 hours after 10 consecutive hours off duty. This is the hard cap on driving time per shift. Once you hit 11 hours behind the wheel, you must stop driving regardless of how much time remains in your 14-hour window.
2. The 14-Hour On-Duty Window
You may not drive after the 14th consecutive hour after coming on duty, following 10 consecutive hours off duty. This clock runs continuously from the moment you start any on-duty activity. Off-duty time within the 14-hour window does not pause the clock unless you use the split sleeper berth provision.
3. The 30-Minute Break Requirement
You must take a 30-minute break after 8 cumulative hours of driving time. The break can be satisfied by any non-driving period of 30 consecutive minutes: off-duty, sleeper berth, or on-duty not driving. This was changed in the 2020 final rule to add more flexibility.
4. The 60/70-Hour Weekly Limit
You may not drive after 60 on-duty hours in any 7 consecutive days (for carriers not operating every day) or 70 on-duty hours in any 8 consecutive days (for carriers operating every day). Most trucking companies use the 70-hour/8-day cycle.
5. The 34-Hour Restart
You may restart your 60-hour or 70-hour clock by taking 34 or more consecutive hours off duty. After a valid restart, your weekly on-duty hours reset to zero. This is optional; you can also use the rolling recalculation method instead. For a deep dive, see our 34-hour restart guide.
All Rules Apply Simultaneously
The 11-Hour Driving Limit Explained
The 11-hour rule under 49 CFR 395.3(a)(3) is the most straightforward HOS regulation. After taking 10 consecutive hours off duty, you may drive for a maximum of 11 hours. Every minute your vehicle is in motion counts against this limit. The only way to reset it is another 10 consecutive hours off duty (or a valid split sleeper berth combination).
How the 11-Hour Clock Works
Start: Your 11-hour driving clock begins the first time you move the vehicle after your 10-hour off-duty period. Pre-trip inspections, fueling, and loading do not consume driving time but they do start your 14-hour window.
Pauses: Unlike the 14-hour window, the 11-hour driving clock pauses whenever you stop driving. If you drive for 4 hours, spend 2 hours at a shipper loading, then drive again, you have used 4 of your 11 driving hours with 7 remaining.
Reset: The only way to get a fresh 11 hours is 10 consecutive hours off duty. A split sleeper berth combination (7/3 or 8/2 split) can also satisfy this requirement under specific conditions.
Track Driving Minutes, Not Just Hours
The 14-Hour On-Duty Window
The 14-hour rule under 49 CFR 395.3(a)(2) is the regulation that catches the most drivers off guard. Once you begin any on-duty activity after your 10-hour off-duty period, a 14-hour clock starts counting down. You cannot drive after the 14th hour, even if you have driving time remaining on your 11-hour clock.
The critical difference between the 14-hour window and the 11-hour driving limit: the 14-hour clock does not stop. If you come on duty at 6:00 AM, your driving window closes at 8:00 PM regardless of how much time you spent off duty, at a shipper, in traffic, or eating lunch during that period. The only exceptions involve the split sleeper berth provision and certain HOS exemptions.
The 14-Hour Trap
The 30-Minute Break Requirement
Under 49 CFR 395.3(a)(3)(ii), drivers must take a break of at least 30 consecutive minutes after accumulating 8 hours of driving time. This break must occur before you can drive again. Prior to the 2020 HOS final rule, the break had to be taken off duty. The updated rule allows the break to be satisfied by any period of 30 consecutive minutes in off-duty, sleeper berth, or on-duty not driving status.
| Aspect | Old Rule (Pre-2020) | Current Rule (2020+) |
|---|---|---|
| When required | After 8 hours of driving | After 8 hours of driving |
| Qualifying status | Off-duty or sleeper berth only | Off-duty, sleeper berth, OR on-duty not driving |
| Duration | 30 consecutive minutes | 30 consecutive minutes |
| Practical impact | Had to find parking or stop completely | Time at shipper/receiver counts as break |
Use Loading Time as Your Break
The 60/70-Hour Weekly Limit
The weekly limit under 49 CFR 395.3(b) caps your total on-duty hours over a rolling period. Carriers that do not operate commercial vehicles every day of the week follow the 60-hour/7-day cycle. Carriers that operate every day follow the 70-hour/8-day cycle. Most over-the-road trucking companies use the 70/8 cycle.
Unlike the daily rules, the weekly limit counts all on-duty time, not just driving time. Every hour you spend loading, fueling, doing paperwork, performing pre-trip inspections, or any other work-related activity counts against your 60 or 70 hours. This is why efficient time management at shippers and receivers directly affects how many miles you can drive in a week.
Rolling Recalculation vs 34-Hour Restart
You have two methods to manage your weekly clock:
Rolling Recalculation
Each day at midnight, the oldest day drops off your 7 or 8-day window. If you worked 12 hours eight days ago, those 12 hours come back to you today. This method works well for drivers who take regular time off throughout the week.
34-Hour Restart
Taking 34 consecutive hours off duty resets your entire weekly clock to zero. This is often used over weekends when freight volume dips. See our restart rules guide for strategies on timing your restart.
The 34-Hour Restart Provision
Under 49 CFR 395.3(c), the 34-hour restart allows drivers to reset their 60-hour or 70-hour clock by taking at least 34 consecutive hours off duty. After a valid restart, your accumulated on-duty hours reset to zero and you start a fresh weekly cycle. The restart has no restrictions on when it must begin or how many times you can use it. The two-night rest requirement and once-per-week limit that were briefly introduced were suspended indefinitely by FMCSA.
Strategic use of the restart can significantly impact your weekly earning capacity. For a complete breakdown of restart timing strategies, scenarios, and common pitfalls, read our dedicated 34-hour restart rules guide.
Property-Carrying vs Passenger-Carrying Rules
HOS rules differ depending on whether you operate a property-carrying CMV or a passenger-carrying CMV. Most freight trucking falls under the property-carrying rules, but drivers who switch between the two need to understand the differences.
| Rule | Property-Carrying | Passenger-Carrying |
|---|---|---|
| Maximum driving time | 11 hours | 10 hours |
| On-duty window | 14 hours | 15 hours |
| Required off-duty before driving | 10 consecutive hours | 8 consecutive hours |
| Weekly limit | 60/7 or 70/8 | 60/7 or 70/8 |
| 30-minute break | After 8 hours driving | Not required (federal) |
| Split sleeper available | Yes (7/3 or 8/2) | No |
Passenger-Carrying Is Stricter on Driving
2025-2026 HOS Updates and Proposed Changes
The core HOS rules have been stable since the September 2020 final rule took effect. However, several developments heading into 2026 are worth tracking:
Increased Enforcement of ELD Data Quality
FMCSA has increased focus on ELD data integrity during roadside inspections. Officers are more trained to detect unassigned driving time, edited records, and patterns suggesting data manipulation. This means accurate ELD usage is more critical than ever for HOS compliance.
ELD Device Deregistrations
In early 2026, FMCSA removed 9 ELD devices from the registered list, with an April 14, 2026 compliance deadline. Operating with a deregistered device carries the same HOS violation penalties as operating without an ELD. Check our ELD violations guide for details on fines and the transition timeline.
Ongoing Petitions for Split Sleeper Flexibility
Industry groups continue to petition FMCSA for additional split sleeper berth flexibility, including proposals for a 6/4 split option. As of February 2026, no formal rulemaking has been initiated, but the topic remains active in FMCSA advisory committee discussions. Any changes would go through the standard rulemaking process with a public comment period before implementation.
CSA 2.0 Methodology Changes
FMCSA's ongoing CSA methodology updates may change how HOS violations are weighted in your CSA score. The HOS Compliance BASIC remains one of the most scrutinized categories, and proposed changes could alter severity weights and intervention thresholds. Monitor FMCSA announcements for any finalized changes.
No Major HOS Rule Changes in 2026
How ELD Requirements Connect to HOS
The ELD mandate exists specifically to enforce HOS compliance. Your ELD automatically records driving time when the vehicle is in motion, calculates your remaining hours across all HOS rules, and makes your records available for roadside inspection. Understanding how your ELD tracks HOS is essential for staying compliant.
Automatic Driving Detection
Your ELD automatically records driving time when the vehicle moves above 5 mph. You cannot edit automatically recorded driving time under 49 CFR 395.8(c). This prevents the log manipulation that was common with paper logs and older AOBRDs.
Real-Time HOS Countdown
Most ELDs display your remaining driving hours, on-duty window, break requirement, and weekly hours in real time. Use these counters actively while driving. If your ELD shows 45 minutes of driving time remaining, plan your stopping point now rather than hoping you make it.
Violation Alerts
Compliant ELDs warn you before you are about to exceed any HOS limit. These warnings typically trigger at 30 minutes, 15 minutes, and 0 minutes remaining. Do not dismiss these warnings. Treat them as mandatory action items. For more on choosing the right device, see our ELD buying guide.
ELD Violations and HOS Violations Are Different
How O Trucking LLC Keeps You HOS Compliant
Compliance starts at dispatch. Every load plan we build factors in your current HOS status because no load is worth an out-of-service order that parks your truck and damages your CSA record for three years.
Hours-Aware Load Planning
Before we assign any load, we verify your available driving hours, remaining 14-hour window, weekly clock status, and break requirement. If a load requires 9 hours of driving and you have 8 hours and 45 minutes remaining, we find you a different load. We never put you in a position where the only way to make delivery is to violate HOS.
Buffer Time Built Into Every Route
Our load plans include buffer time for traffic, weather, and facility delays. We know that a 6-hour drive on paper often takes 7.5 hours in reality once you factor in construction zones, weigh station stops, and shipper wait times. The buffer prevents you from running up against HOS limits because the load was planned too tight.
Restart Strategy Coordination
When your weekly hours are getting low, we coordinate restart timing with available freight. We help you position for a 34-hour restart at a location where you can pick up a high-paying load immediately after your clock resets, maximizing your earning potential from every restart.
Stay HOS Compliant on Every Load
Our dispatch team builds every load plan around your available hours so you never face pressure to exceed your limits, falsify logs, or risk a violation that damages your CSA score for three years.
