Hours of service compliance BASIC is the bedrock of a safe and profitable fleet, but getting it right can feel like a constant battle for fleet managers and safety directors aiming to keep operations smooth and drivers safe. You’re juggling a lot, trying to keep deliveries on time and your company in the black, all while navigating a spiderweb of complex regulations.
It’s easy to feel the pressure when you hear stories about hefty fines or see a competitor’s CSA score creep into the alert zone. You might worry about a single logbook error triggering a costly audit or wonder if your training is really preventing fatigue-related risks.
Too many managers find themselves just reacting—chasing down paperwork, trying to decipher cryptic ELD alerts, and just hoping everyone is logging their time correctly. This constant fire-fighting can leave you feeling like you’re always one step behind a potential violation. This guide is here to cut through that complexity.
We’ll break down the essential HOS rules into clear, manageable chunks and show you how to build a compliance program that actually works, protecting both your business and your people.
Understanding the Core Challenge
At its heart, the goal of Hours of Service is simple: combat driver fatigue, a leading cause of truck crashes. The DOT regulations create a framework for work and rest, including key rules like the 11-hour driving limit after 10 consecutive hours off-duty and the 60/70-hour weekly caps. Simple enough on paper, right? But applying them in the real world is where things get messy.
Interestingly, an FMCSA report on the 2020 HOS changes noted that the percentage of driver inspections with at least one HOS violation actually went up after the new rules were implemented. This just goes to show that staying compliant is still a major hurdle for many fleets.
Building a Proactive System
A strong compliance program isn’t built on luck; it’s built on clear communication and solid processes. For you, making sure everyone is on the same page with HOS policies is absolutely critical.
Ultimately, mastering your Hours of Service compliance BASIC isn’t just about avoiding fines. It’s about creating a culture of safety that benefits everyone. This approach reduces risk, helps with driver retention, and strengthens your company’s reputation with shippers and insurers. With the right knowledge and systems, you can move from putting out fires to proactively managing safety.
To get a head start, you can explore our detailed breakdown of the new hours of service rules.
The Four Core HOS Rules You Must Know
At the heart of Hours of Service compliance are four fundamental limits that dictate every driver’s day and week. For any fleet manager or owner, getting these rules down cold is non-negotiable. They’re the first thing an inspector will look at and the bedrock of preventing driver fatigue. If you don’t have a solid handle on these four pillars, you’re setting yourself up for violations, fines, and a hit to your safety record.
Ever heard your team talk about their “clocks”? They’re not just talking about the time of day. They’re juggling a set of interconnected timers mandated by federal regulations. These rules aren’t just random numbers; they’re a carefully designed system to make sure drivers get the rest they need to operate safely.
The whole system is built around four key rules that all work together. We’ll break down the 14-hour driving window, the 11-hour driving limit, the required 30-minute break, and the 60/70-hour weekly limit. Understanding how each one works on its own—and how they affect each other—is the only way to keep your logs clean.
This timeline shows just how much the Hours of Service rules have evolved, moving from the old paper log days to today’s ELD-driven world.

This shift really underscores the industry’s move toward better accuracy and accountability in how driver hours are tracked.
To make these rules easier to digest, here’s a quick-glance table that summarizes what you need to know. We’ll dive into the specifics of each one right after.
Core Hours Of Service Limits At A Glance
| HOS Rule | What It Means | Common Pitfall |
|---|---|---|
| 14-Hour Driving Window | You have 14 consecutive hours to work after coming on duty. This clock does not stop. | Forgetting that any on-duty activity (like inspections or fueling) starts the clock. |
| 11-Hour Driving Limit | Within the 14-hour window, you can drive for a maximum of 11 total hours. | Miscalculating total drive time when it’s broken up by non-driving tasks. |
| 30-Minute Break | You must take a 30-minute break after 8 cumulative hours of driving. | Taking a break that’s too short or trying to drive again before the full 30 minutes is up. |
| 60/70-Hour Limit | Limits total on-duty time to 60 hours in 7 days or 70 hours in 8 days. | Losing track of the “rolling” total, leading to a surprise violation mid-week. |
Now, let’s unpack exactly what each of these means for your daily operations.
1. The 14-Hour Driving Window
Think of the 14-hour window as a daily countdown clock that you can’t pause. The second your driver starts any kind of on-duty activity—whether it’s a pre-trip inspection, fueling up, or heading to a shipper—that 14-hour clock starts ticking down.
Once that 14-hour period is over, they are legally forbidden from operating a commercial motor vehicle until they’ve taken 10 consecutive hours off-duty. This rule is absolute, regardless of how much time they actually spent driving.
For example, if someone on your team starts their day at 6:00 AM, their 14-hour window slams shut at 8:00 PM. Even if they only drove for six of those hours, they must stop driving for the day by 8:00 PM, period.
2. The 11-Hour Driving Limit
Inside that 14-hour window, there’s another, separate limit specifically for time spent behind the wheel. Your drivers are allowed a maximum of 11 hours of actual driving time.
These 11 hours don’t have to be all in one stretch. A driver could drive for four hours, take a break, do some on-duty yard work for two hours, and then get back on the road for another seven hours, as long as it all happens within their 14-hour window.
The key takeaway here is that the 11-hour driving clock and the 14-hour duty clock run at the same time. A driver can run out of either one first, and as soon as one limit is hit, driving has to stop until they complete a full 10-hour off-duty period.
3. The 30-Minute Break Requirement
To fight off fatigue during a long haul, the regulations mandate a break. After a driver has accumulated 8 hours of driving time, they are required to take at least a 30-minute break before they can legally drive again.
This break can be logged as Off-Duty, Sleeper Berth, or even On-Duty Not Driving. The important part is that it must be 30 consecutive minutes where no driving occurs. This rule ensures your team has a chance to step away, rest, and refocus during their shift.
4. The 60/70-Hour Weekly Limit
Finally, HOS rules put a cap on the total number of on-duty hours a person can work over a rolling period of days. This is designed to prevent the dangerous, cumulative fatigue that builds up over a tough work week.
This rule comes in two flavors:
- 70-Hour / 8-Day Limit: Your drivers cannot be on duty for more than 70 hours in any 8-consecutive-day period. This is the standard for most fleets that operate seven days a week.
- 60-Hour / 7-Day Limit: Your drivers cannot be on duty for more than 60 hours in any 7-consecutive-day period.
A driver can get all their hours back by taking 34 consecutive hours off-duty. If you want to get into the nitty-gritty of this, you can learn more about how the 34-hour reset works. Keeping a close eye on these weekly totals is an essential piece of long-term HOS compliance.
How Common HOS Violations Hammer Your CSA Scores
Knowing the Hours of Service rules is one thing. Understanding what happens when you break them is something else entirely. For you, every HOS violation is more than a roadside headache—it’s a direct hit to your company’s safety record and, ultimately, your bottom line.
You’ve seen how it happens. A driver pushes the 11-hour limit just to make a delivery time. Another forgets to log their 30-minute break. Maybe someone makes a simple “form and manner” mistake on their ELD. These are the exact kinds of slip-ups inspectors are trained to find, and they all feed into one of the most critical metrics for your fleet: your Compliance, Safety, Accountability (CSA) score.
Each violation carries a certain weight, and those points add up fast. The Hours of Service Compliance BASIC (Behavior Analysis and Safety Improvement Category) is one of seven buckets the FMCSA uses to rate your fleet’s safety performance. A few high-point violations can quickly shove your score into the “alert” threshold, triggering a cascade of problems that are a real pain to reverse.
The Math Behind the Violations
Not all violations are created equal in the eyes of the FMCSA. They assign “severity weights” to each specific infraction, ranging from 1 to 10, with 10 being the worst of the worst. A simple logbook error might earn you a slap on the wrist, but blowing past the 11 or 14-hour limits is a high-point offense that gets immediate attention.
Here are some of the most common violations and the damage they do:
- Exceeding the 11-Hour Driving Limit: This is a huge red flag for inspectors. It screams “driver fatigue” and carries a heavy severity weight of 7 points.
- Exceeding the 14-Hour Duty Window: Just like the 11-hour rule, this violation will also cost you 7 points.
- False Report of Record of Duty Status: This is one of the most serious HOS violations you can get. It suggests you’re deliberately trying to cheat the system and is weighted at 7 points.
- No Record of Duty Status (When Required): Not having logs when you’re supposed to is a big deal. This violation will typically add 5 points to your score.
- Form and Manner Violations: These are mistakes in how the log is filled out. They might seem minor, but they can still tack on anywhere from 1 to 5 points.
To make matters worse, these points are time-weighted. A violation you got last month hurts your score more than one from a year ago. Violations stick to your record for a full 24 months, so one bad day on the road can follow you for a long, long time.
From a Roadside Stop to a Real Business Risk
When your Hours of Service Compliance BASIC score starts to climb, it sends a clear warning to the FMCSA, your insurance provider, and even your customers. Cross that alert threshold, and you can bet you’ll be getting a lot more attention at weigh stations and roadside inspections.
A single driver’s logbook mistake doesn’t just stay with that driver. It becomes part of your company’s permanent safety record, directly influencing everything from your insurance rates to your ability to book profitable loads.
For you, this translates to real dollars and cents. Fines for non-compliance can run anywhere from $1,000 to $15,000 per violation. A high CSA score can also cause your insurance premiums to spike by 25% to 50%. Even with ELDs in every truck, about 20% of all inspections still uncover HOS issues, showing just how tough this problem is to stamp out.
This elevated risk profile makes your fleet less attractive to the shippers who pay the bills. They check CSA scores, and a high HOS score is often enough for them to choose a competitor over you. Poor hours of service management doesn’t just cost you in fines; it costs you in lost business.
To get a better handle on this critical safety metric, dive into our detailed guide on the HOS Compliance BASIC.
Getting a Handle on Your ELDs and Records
Your Hours of service compliance BASIC score reflects more than just knowing the rules, it’s about rock-solid record keeping. Your Electronic Logging Device (ELD) is right at the heart of it all.
As a manager, you were probably glad to see paper logs go. But you’ve also figured out that ELDs aren’t a “set it and forget it” gadget. They need constant, hands-on management to keep you out of hot water with the DOT.
You know the drill. An unassigned driving event pops up, and you’re left guessing who was behind the wheel. Or a driver calls, stranded, with a malfunctioning ELD hundreds of miles from help. These aren’t just tech hiccups; they’re compliance landmines waiting to go off.
An ELD is a fantastic tool, but it’s only as good as the team using it and the systems you have in place to manage all that data. This section will walk you through building a bulletproof ELD program, from the documents in the cab to your duties back at the office.

What Every Truck Must Carry
Real compliance starts before the wheels even roll. When one of your drivers gets pulled for an inspection, the officer expects them to have the right paperwork ready to go, no fumbling around.
Make sure every single truck has these four things on board:
- An ELD User Manual: The official guide explaining how to use that specific ELD.
- An Instruction Sheet: A simple, step-by-step guide on transferring HOS data to an inspector.
- An ELD Malfunction Guide: Clear instructions on exactly what to do—and what records to keep—if the device breaks down.
- A Supply of Blank Paper Logs: At least an 8-day supply. This is non-negotiable for when the ELD fails and the driver has to switch back to manual logging.
The Driver’s Role In ELD Management
Your drivers are on the front lines of HOS compliance. Their daily habits with the ELD can make or break your Hours of Service compliance BASIC and all of your other BASIC scores. It’s their job to log in, certify their logs are accurate at the end of each 24-hour period, and log out. Simple as that.
They also need to know how to properly use annotations to explain any edits or special driving statuses. This means correctly logging Personal Conveyance (PC) for off-duty personal use and Yard Moves (YM) for on-duty shuffles around a shipper’s property. Getting these statuses wrong is a rookie mistake and an easy violation to avoid. Nailing the difference is a critical part of mastering e-logs for trucks.
Your job as a manager is to train every driver not just on the HOS rules, but on the nuts and bolts of your specific ELD. A driver who doesn’t know how to annotate a log correctly can cause big compliance headaches for everyone.
Your Responsibilities Back at the Office
While your team handles the day-to-day, the buck stops with you when it comes to keeping records. The FMCSA mandates that you hold on to all HOS records and their supporting documents for a minimum of six months.
And it’s not just about archiving the raw ELD data. HOS supporting documents are equally important because they prove the logs are accurate. This includes things like:
- Bills of lading and dispatch records
- Expense receipts (fuel, food, tolls, lodging)
- Messages from your fleet management system
- Payroll records
The secret to being audit-ready is to regularly check these documents against your drivers’ logs. It’s the best way to find and fix issues before a DOT auditor finds them for you.
Handling ELD Malfunctions Correctly
When an ELD inevitably goes on the fritz, there’s a specific protocol you and your driver must follow. The driver needs to notify you in writing (an email or text works) within 24 hours.
From that point, the driver has to reconstruct their logs for the current 24-hour period and the previous seven days using those paper logs they have in the cab. You then have eight days to get the device repaired or replaced. If it’s going to take longer, you must file for an extension with the FMCSA. Following these steps to the letter shows an inspector you’re serious about compliance, even when technology lets you down.
A Practical Checklist for Strong HOS Compliance
Knowing the Hours of Service basics is one thing, but turning that knowledge into consistent, everyday action is what separates a safe fleet from a risky one. Moving from theory to practice isn’t automatic; it requires a clear, repeatable process.
Think of it like a pre-trip inspection for your entire safety program. You wouldn’t let a truck leave the yard without checking the tires and brakes, so you shouldn’t run your fleet without a regular check on your HOS procedures. This checklist is your guide to getting proactive about HOS management.

Foundational Policies and Training
Everything starts with clear expectations. Your team can only follow the rules they understand, which makes solid policies and ongoing training completely non-negotiable. Building a system around these policies is key; a great resource for this is creating Standard Operating Procedures.
- Create Clear Company Policies: Draft and distribute written policies for things like Personal Conveyance, Yard Moves, and handling ELD edits. Make sure every driver signs off, confirming they’ve read and understood them.
- Schedule Regular HOS Training: Set up quarterly HOS refresher sessions for all drivers. These are perfect for hitting on the most common violations and any recent changes to the regulations.
- Onboard New Drivers Thoroughly: The orientation part of your driver safety training program needs to include a deep dive into HOS rules and hands-on training with your specific ELD system. Don’t let them hit the road until they’re confident.
Proactive Log Auditing and Review
Don’t wait for a roadside inspection to find problems. Consistent internal audits are your single best defense against violations and climbing CSA scores.
Proactive log auditing isn’t about catching drivers making mistakes; it’s about finding gaps in your system and training before they become costly violations. This shifts your role from enforcer to coach.
In 2022 alone, authorities cited over 100,000 HOS violations at the roadside. A huge chunk of those were for the 11-hour and 14-hour rules. At My Safety Manager, our compliance services have helped over 3,300 clients cut their violations by up to 35% and lower their insurance costs by an average of 15%.
Daily and Weekly Action Items
Build these steps right into your regular workflow to stay ahead of compliance issues. This systematic approach is the backbone of an effective safety program.
- Review Unassigned Driving Miles Daily: Every single morning, log into your ELD portal and assign any unidentified driving segments from the day before. Don’t let these pile up.
- Conduct Weekly Log Audits: Set a recurring task to audit at least 10% of your driver logs each week. Look for patterns, common errors, and potential violations that need to be addressed.
- Monitor ELD Reports: Your ELD provider has powerful reporting tools. Use them to flag drivers who are frequently pushing their HOS limits. This lets you step in and have a conversation before a violation happens.
- Perform Post-Trip Reviews: When drivers get back to the terminal, take a few minutes to go over any log edits or annotations from their trip. This ensures they were done correctly and compliantly.

Hours of Service Compliance BASIC: Frequently Asked Questions
Hours of service compliance can feel like a moving target, especially when you’re managing the day-to-day chaos of a busy fleet. As the fleet owner or safety manager, you’re the final backstop for any questions your team has, and getting the answers right is critical for avoiding violations. You’ve probably heard the same questions over and over, from handling tricky ELD statuses to figuring out what to do when someone is stuck in traffic.
You’re not alone. The nuances of HOS rules create a ton of confusion, and a simple misunderstanding can easily lead to a logbook error, a roadside violation, and a nasty hit to your CSA score. When these small mistakes get repeated across a fleet, they quickly add up to one big compliance headache.
This FAQ section is designed to give you quick, clear answers to the most common questions we hear from fleet managers just like you. Think of this as your go-to guide for those nagging HOS uncertainties. We’ll tackle everything from personal conveyance to what really counts as on-duty time.
What is Personal Conveyance and when can it be used?
Personal Conveyance (PC) is when a driver uses the commercial motor vehicle for personal reasons while officially off-duty. The key is that the truck must be unladen, and the driver cannot be doing anything that benefits the motor carrier. For example, driving from a shipper to a nearby truck stop for a meal is a valid use of PC. However, driving to the next pickup location is considered advancing the load and is not a valid use of PC.
What happens if a driver exceeds HOS limits due to traffic?
The FMCSA provides an “adverse driving conditions” exception. If a driver encounters unexpected weather or traffic, they can drive for up to two additional hours beyond the normal 11 and 14-hour limits to reach a safe location. The driver must annotate the reason in their ELD. This is for truly unforeseen situations, not predictable rush hour traffic.
How long must HOS records be kept?
You must keep all Hours of Service records and supporting documents (like fuel receipts and bills of lading) for a minimum of six months. Keeping these records organized and accessible is critical for passing a DOT audit.
Does on-duty, not-driving time count against the 14-hour clock?
Yes. The 14-hour driving window is a consecutive clock that starts the moment a driver begins any on-duty activity, whether it’s driving, inspecting the truck, or waiting to be loaded. It does not stop for breaks or other activities.
What is the difference between Off-Duty and Sleeper Berth?
Both statuses mean the driver is relieved of all work responsibilities. The main difference is location. “Off-Duty” is used when resting away from the truck (e.g., at home), while “Sleeper Berth” is used only when resting in the truck’s sleeper compartment. Both can be combined to meet the 10-hour rest requirement.
Can paper logs be used if an ELD malfunctions?
Yes, but you must follow a strict protocol. The driver must notify you in writing within 24 hours. They then switch to paper logs and reconstruct their logs for the current day and the past seven days. You have eight days to repair or replace the ELD.
What are common HOS violations that hurt CSA scores?
The most common and highest-point violations include exceeding the 11-hour driving limit, violating the 14-hour duty window, and falsifying a record of duty status. Each of these can add 7 points to your CSA score, significantly increasing your audit risk and insurance premiums.
Regulatory References
For fleet managers and owners who want to go straight to the source, having the official regulations is invaluable. The Federal Motor Carrier Safety Regulations (FMCSRs) are the final word during an audit or roadside inspection. Knowing where to find the key rules empowers you to make confident decisions.
Here are direct links to the key sections of the electronic Code of Federal Regulations (eCFR) that govern Hours of Service. We recommend bookmarking these pages for quick access.
- Part 395 Hours of Service of Drivers: This part covers all the core HOS rules, from driving limits and rest breaks to record-keeping duties.
- § 395.8 Driver’s record of duty status: This section details the specific requirements for how drivers must create and maintain their logs with an ELD.
