Understanding hours of service isn’t just about staying compliant, it’s about maximizing your earning potential while keeping yourself safe out there. Every mile you drive, every load you haul, and every paycheck you earn comes down to how well you handle hours of service (HOS) rules.
Here’s the reality: HOS violations can seriously damage your career. We’re not talking just about fines — though those hurt plenty. You could get put out of service, damage your Compliance, Safety, Accountability (CSA) score, and lose access to good-paying runs. But here’s what most drivers don’t realize: the operators who really know the truck driver hours law inside and out are the ones making better money. They plan smarter routes, waste less time, and actually get more done within the legal limits.
This guide breaks down everything you need to know about HOS rules in 2025. We’ll cover the five main rules that control your workday, the exceptions that can help you when things go sideways, and how a good electronic logging device (ELD) can actually make your life easier instead of harder.
Whether you’re fresh out of driving school or you’ve been rolling for years, mastering these rules and getting the right electronic logbook can mean the difference between scraping by and building a real career in trucking.

What Are Hours of Service Rules?
Hours of service rules tell you how long you can work and drive before the Department of Transportation (DOT) requires you to rest. Bottom line: they exist because fatigued drivers cause accidents. The federal government has the statistics to prove it, and they’re serious about enforcement.
The Federal Motor Carrier Safety Administration (FMCSA) handles HOS enforcement. Their job is keeping exhausted drivers off the road, and since ELDs became mandatory, they’ve gotten much better at catching violations. The data shows it’s working: fewer HOS violations mean fewer crashes.
If you drive a commercial vehicle over 10,001 pounds across state lines, these rules apply to you. That includes long-haul, regional, and some local drivers depending on what you’re hauling. Some states have their own rules for drivers who stay in-state, but most follow the federal standards.
The Legal Framework
HOS regulations come from Federal Motor Carrier Safety Regulation 49 CFR Part 395. This comprehensive regulation covers how long you can drive, when you have to rest, and what happens if you violate the rules.
The federal law for truck driver hours sets the baseline, but states can make their own rules more restrictive if they choose. If you’re running interstate, you follow whichever rule is stricter. Cross state lines? You’re playing by federal rules, period.
Get caught violating HOS? You’re looking at fines anywhere from a few hundred to several thousand dollars per violation. Multiple violations to the truck driver hours of service USA laws can get you parked until you resolve the problem. Plus, every violation hits your CSA score, which affects your insurance rates and job prospects.
The major change came in 2020 when the FMCSA modified several rules to give drivers more flexibility. They extended the short-haul exemption and added options for splitting your 10-hour break. Understanding these changes can help you work more efficiently in 2025.
The Five Core HOS Rules Every Trucker Must Know
Rule #1: The 11-Hour Driving Limit
This one’s straightforward: you get 11 hours of driving time, then you’re done until you take 10 hours off. No exceptions, no “just five more minutes to get to the truck stop.” Eleven hours means eleven hours.
“Driving” means you’re behind the wheel with the truck moving. Loading, unloading, pre-trip inspections, waiting at customers — none of that counts as driving time. But once you hit 11 hours of actual driving, you’re legally required to shut down.
Don’t try to push it. Even one minute over 11 hours is a violation, and DOT officers have zero tolerance for this. Smart drivers set their ELD to warn them at 10.5 hours so they have time to find a safe place to park.
The key is planning ahead. Know your route, figure out where traffic gets heavy, and plan your fuel stops around your break times. Once you hit that 11-hour limit, your driving day is over whether you’re five miles from home or 500.
Rule #2: The 14-Hour On-Duty Window
Here’s where it gets complex. You have 14 consecutive hours to get all your work done, including that 11 hours of driving. The key word is consecutive — this clock never stops ticking once you start working.
Taking a break doesn’t pause the 14-hour clock like it does the driving clock. Load for two hours? That counts. Wait three hours at a customer? That counts too. Eat lunch for 30 minutes? Still counts. Everything from the time you log on-duty until you log off-duty eats into those 14 hours.
This is where experienced drivers separate themselves from the rest. Don’t start your 14-hour clock until you’re actually ready to work. If your load doesn’t pick up until 10 AM, don’t log on-duty at 6 AM just to pass time. Plan your day to minimize waiting around, and always have a backup plan when customers run late.
Treat those 14 hours like they’re valuable, because they are. Once they’re gone, you’re done driving until you take a full 10-hour break.
Rule #3: The 30-Minute Break
After eight hours of driving, you need to take at least 30 minutes off before you can drive again. This break has to be logged as off-duty, sleeper berth, or — thanks to the 2020 changes — on-duty not driving time.
The new rules made this more flexible. You can now count loading and unloading time toward your break as long as you’re not driving for 30 straight minutes. This is significant for drivers who spend time at docks.
Plan your break strategically. Don’t wait until you hit exactly eight hours of driving, work it around fuel stops, meals, or customer appointments. Many drivers take their 30-minute break while getting loaded or unloaded, which handles two requirements at once.
The biggest mistake? Forgetting about it completely. Quality ELDs will warn you when you’re getting close to eight hours, but you should already know when and where you’re taking that break before you even start driving.
Rule #4: Weekly Limits (60/70 Hour Rules)
You’re limited to either 60 hours on-duty in 7 consecutive days (if your carrier operates 6 days or fewer) or 70 hours on-duty in 8 consecutive days (if your carrier operates 7 days a week). These are rolling limits that reset daily at midnight.
Every day, you drop the oldest day from your calculation and add the current day. This means your available hours change daily based on what you worked a week ago. All on-duty time counts—driving, loading, waiting at customers, inspections, everything.
Smart drivers track their weekly totals and plan lighter days when they’re approaching the limit. Once you hit your weekly limit, you can still work but you can’t drive until you either get hours back through the rolling calculation or take a 34-hour restart.
Rule #5: The 34-Hour Restart
The 34-hour restart resets your weekly hour calculation by taking at least 34 consecutive hours off-duty. After a valid restart, your 60 or 70-hour limit starts fresh.
The restart must include two periods between 1:00 AM and 5:00 AM to be valid, you can’t just take any 34 hours off and have it count. Most drivers schedule restarts over weekends when freight rates are lower anyway.
Strategic restart timing can boost your earning potential. Starting Monday with full hours available often means better load opportunities and higher pay rates than limping through the week with limited hours.
HOS Compliance and the ELD Mandate
Since 2019, most commercial drivers have been required to use electronic logging devices instead of paper logs to track their hours of service. The ELD mandate applies to drivers who are required to maintain records of duty status (RODS) and operate vehicles manufactured after 2000.
The FMCSA maintains a list of registered electronic logging systems that have been self-certified by manufacturers as compliant with federal regulations. However, being on this list doesn’t guarantee an electronic logbook actually meets all requirements, it just means the manufacturer claims it does. This is why choosing a reputable ELD provider with proven reliability is crucial.
Key exemptions include drivers using vehicles with engines manufactured before 2000 and those who qualify for the short-haul exception. However, many exempt drivers choose to use electronic logs anyway because of the operational benefits they provide beyond basic compliance.
Penalties for elog violations can be severe, including fines up to $12,464 for drivers and carriers who fail to use compliant devices. During inspections, officers can also place drivers out of service for these violations, which means no driving until the problem is fixed.
How ELDs Ensure Compliance
Modern ELDs automatically track your driving time by connecting directly to your vehicle’s engine control module (ECM). This connection eliminates the possibility of “forgetting” to log driving time or accidentally miscalculating your hours — the system records everything automatically.
Real-time violation alerts are one of the biggest advantages of quality ELD systems. Instead of discovering you’re in violation during a roadside inspection, good electronic logbooks warn you before you exceed legal limits. These alerts give you time to find safe parking or adjust your plans before breaking HOS rules.
The systems also maintain detailed records that are easily accessible during DOT inspections. Officers can review your logs electronically without requiring you to fax or email anything, which streamlines the inspection process and reduces the chance of paperwork-related violations.
Common ELD Challenges Truckers Face
Not all ELDs are created equal, and many drivers struggle with systems that create more problems than they solve. Poor user interface design tops the list of complaints — systems that require multiple taps for basic functions or use confusing menu structures can actually distract drivers and make compliance harder.
Hardware reliability issues cause major headaches on the road. Electronic logbooks that frequently lose connection to your vehicle’s ECM, have weak Bluetooth signals, or fail during critical moments can leave you unable to log required information. The most frustrating problems include:
- Connection failures during DOT inspections when you need to show your logs.
- System crashes that lose hours of recorded data.
- Poor GPS accuracy that shows incorrect locations during violations.
- Battery drain that kills your phone or tablet when you need it most.
Customer support becomes critical when technical problems arise, but many ELD providers fall short here. Limited support hours, long hold times, or representatives who don’t understand trucking operations can leave you stranded when you need help most. The best providers offer support every day by knowledgeable staff who understand the urgency of compliance issues.

Maximizing Your HOS Efficiency: Strategic Tips
Successful drivers don’t just follow the truck driver hours law, they use strategic planning to maximize productivity within legal limits. Pre-trip planning makes the difference between profitable runs and wasted time sitting in truck stops.
Route planning should always factor in HOS considerations. Know where traffic typically slows down, identify truck stops and rest areas along your route, and plan fuel stops that align with your mandatory break requirements. Smart drivers also research customer locations ahead of time to avoid getting stuck in areas with limited parking when their hours run out.
Load timing and delivery window management require honest communication with dispatchers and customers. Don’t accept impossible schedules that force you to choose between HOS violations and on-time delivery. Build buffer time into your schedule for unexpected delays, and always have backup parking options when delivery appointments run late.
Technology integration beyond basic ELD compliance can significantly improve your efficiency:
- GPS tracking data helps dispatchers make better load assignments based on your location.
- Vehicle diagnostic information allows proactive maintenance scheduling to prevent breakdowns.
- Fuel efficiency monitoring identifies driving habits that waste money.
- Performance analytics show patterns that help optimize your weekly schedules.
The most successful drivers also set personal alerts before reaching legal limits. Instead of waiting for the ELD to warn you at exactly 11 hours, set your own alert at 10.5 hours. This gives you time to find safe, convenient parking rather than scrambling for the nearest truck stop.
Common Violations and How to Avoid Them
Understanding the most frequent HOS violations helps you avoid costly mistakes that can damage your career and earning potential. The top violations happen when drivers misunderstand the rules or try to push legal limits too far.
Driving beyond the 11-hour limit is the most common violation, often happening when drivers misjudge travel time or get caught in unexpected traffic. The solution is conservative planning — always assume traffic will be worse than expected and build extra time into your schedule. Remember, even one minute over 11 hours counts as a violation.
Operating past the 14-hour window catches many drivers off guard because they don’t account for loading delays or customer wait times. Start your 14-hour clock as late as possible, communicate realistic delivery times with customers, and have parking backup plans ready when appointments run long.
Missing or taking inadequate 30-minute breaks happens when drivers forget about the requirement or try to shortcut it. The 2020 rule changes made this easier by allowing on-duty not driving time to count, but you still need a full 30 consecutive minutes without driving. Plan these breaks around natural stopping points like fuel, food, or loading activities.
Weekly hour limit violations often result from poor record keeping or misunderstanding how the 60/70-hour rules work. Use your ELD’s weekly summary features to monitor your total hours, and plan 34-hour restarts strategically to reset your weekly clock when needed.
Prevention strategies focus on building good habits and using technology effectively:
- Daily planning sessions before starting your drive to review hours available and route challenges.
- Regular ELD monitoring throughout the day to track remaining time.
- Communication protocols with dispatch about realistic scheduling and potential delays.
- Emergency procedures for handling unexpected situations that threaten compliance.
The best drivers treat HOS compliance as a competitive advantage rather than a burden. They understand that consistent compliance leads to better CSA scores, lower insurance costs, and access to higher-paying loads that companies reserve for their most reliable drivers.
Future of Truck Driver Hours Law
The trucking industry keeps pushing for more flexibility in HOS rules, but don’t hold your breath waiting for major changes. The federal government moves slowly on these things, and safety always comes first in their decisions.
Recent discussions focus on expanding split sleeper berth options and adding exemptions for specific types of hauling. Technology trends suggest future rules might include fatigue detection systems and advanced driver monitoring beyond basic ELDs.
Here’s the reality: if ELD data shows fewer accidents, regulators might consider more flexibility. If safety improvements stall or violations increase, expect tighter enforcement instead of looser rules. The FMCSA bases everything on hard safety data, not industry complaints about inconvenience.
Don’t plan your career around changes to the laws for truck driver hours that may never happen. Work within current regulations and adapt when official changes actually occur.
Staying Current with Regulations
Stay informed through reliable sources like the FMCSA website, industry publications such as Transport Topics and Overdrive, and professional trucking associations. Many state trucking associations also provide updates on both federal and state-specific regulations.
While quality ELD providers often communicate important regulatory changes that affect their devices, you’re ultimately responsible for staying current with HOS rules. The FMCSA encourages drivers and carriers to sign up for ELD updates to receive notifications when devices are added to or removed from the registered list.
Don’t rely on truck stop rumors or social media for regulatory information. When HOS rules change, you need accurate information from official sources, not secondhand speculation that could get you in trouble.
Conclusion
HOS compliance isn’t negotiable if you want to succeed in trucking. Every violation hits your wallet through fines, damages your CSA score, and costs you access to better-paying loads. But here’s what most drivers miss: operators who really understand these rules turn HOS knowledge into a competitive advantage.
The five core rules control every aspect of your workday, from daily productivity to long-term earning potential. Mastering exceptions and special circumstances can save your career when unexpected situations arise. Most importantly, the right ELD system transforms compliance from a constant headache into a tool that actually helps your business.
