Common HOS Violations and Penalties: The Complete Guide
An Hours of Service violation does more than generate a fine. It triggers an out-of-service order that parks your truck, damages your CSA score for three years, increases your insurance premiums, and makes brokers filter you out of load boards. This guide covers the most common violations, exactly how much they cost, and what you can do to prevent and contest them.

Top 10 Most Common HOS Violations
Based on FMCSA roadside inspection data, these are the HOS violations that appear most frequently. Every one of them is preventable with proper planning and accurate logging.
Exceeding 11-Hour Driving Limit
Driving beyond 11 hours after 10 consecutive hours off duty. This is the single most cited HOS violation. Even one minute over triggers a violation. Your ELD tracks this to the minute, and the officer has immediate access to the data.
Exceeding 14-Hour On-Duty Window
Driving after the 14th consecutive hour since coming on duty. Long shipper wait times are the primary cause. The 14-hour clock does not pause for off-duty breaks within the window, which catches many drivers off guard.
Exceeding 60/70-Hour Weekly Limit
Driving after accumulating 60 hours in 7 days or 70 hours in 8 days of on-duty time. This often happens toward the end of a busy week when drivers lose track of cumulative hours. Check your weekly running total daily.
No 30-Minute Break After 8 Hours Driving
Failing to take 30 consecutive minutes of non-driving time after 8 cumulative hours of driving. Since the 2020 rule change, on-duty not driving time counts, but many drivers still miss the requirement during long solo hauls.
False Record of Duty Status
Any discrepancy between what the ELD recorded and what the driver's logs show. This includes editing drive time to show off-duty, using a personal conveyance status while loaded, or having unaccounted gaps in the log.
No Record of Duty Status (No RODS)
Operating without any records of duty status. This applies when the ELD has no data, the driver has no paper backup, or the prior 7-day records are unavailable. Always carry paper logs as backup.
Insufficient Off-Duty Time
Driving without the required 10 consecutive hours off duty between shifts. Partial off-duty periods (like 8 or 9 hours) do not reset the clock. The 10 hours must be consecutive except when using the split sleeper berth provision.
Operating Without an ELD
Driving a CMV that requires an ELD without one installed and functioning. This includes using a deregistered device after the grace period. See our ELD violations guide for device-specific penalties.
Improper Use of Personal Conveyance
Using personal conveyance status while the vehicle is loaded, while moving toward a shipper or receiver, or for any purpose that could be considered furthering a business objective. Personal conveyance is for personal use only.
Inaccurate Log Entries
Log entries that do not match actual activities: wrong location, incorrect duty status timing, or missing required annotations. Even unintentional inaccuracies can be cited as violations if they affect HOS compliance calculations.
Multiple Violations Per Stop
Fine Amounts Per Violation
HOS violation fines are set by FMCSA under 49 CFR 386 and are adjusted periodically. The following table shows the current fine ranges based on violation severity and whether it is a first or repeat offense.
| Violation | First Offense | Pattern/Willful |
|---|---|---|
| Exceeding 11-hour driving limit | $1,000 - $2,750 | $2,750 - $16,000 |
| Exceeding 14-hour window | $1,000 - $2,750 | $2,750 - $16,000 |
| Exceeding 60/70-hour limit | $1,000 - $2,750 | $2,750 - $16,000 |
| No 30-minute break | $1,000 - $2,750 | $2,750 - $16,000 |
| No RODS / missing records | $1,000 - $2,750 | $2,750 - $16,000 |
| False record of duty status | $2,750 - $16,000 | $16,000+ / CDL disqualification |
| Carrier requiring driver to violate HOS | $16,000 per occurrence | $16,000+ / operating authority action |

Out-of-Service Consequences
Most HOS violations result in an out-of-service (OOS) order. When an officer determines you have exceeded any HOS limit, your truck is parked on the spot for a minimum of 10 consecutive hours. You cannot drive, you cannot move the vehicle, and the officer determines where you park.
Immediate Revenue Loss
A 10-hour OOS order means a full day of lost revenue. For an owner-operator averaging $2.50 per mile and 500 miles per day, that is $1,250 in direct revenue loss before accounting for the fine, the missed next load, and potential detention charges at the receiver for the late delivery.
Cascading Schedule Disruption
A 10-hour forced stop does not just affect today. It pushes back tomorrow's load, which may push back the next day's load. A single OOS order can disrupt an entire week of planned loads. Brokers and shippers do not care why you were late; they care that their freight did not arrive on time.
How HOS Violations Affect Your CSA Score
Every HOS violation from a roadside inspection flows into the HOS Compliance BASIC within FMCSA's CSA scoring system. Each violation receives a severity weight from 1 (minor) to 10 (critical), multiplied by a time weight that makes recent violations count more heavily. The resulting score is compared against peer carriers to generate your BASIC percentile.
Severity Weights for Common HOS Violations
| Violation | Severity Weight |
|---|---|
| Exceeding 11-hour driving limit | 7 |
| Exceeding 14-hour on-duty window | 7 |
| Exceeding 60/70-hour limit | 7 |
| False record of duty status | 10 |
| No record of duty status | 5 |
| No 30-minute break | 4 |
Time Weighting Hits Hardest in Year One
Driver vs Carrier Liability
HOS violations create liability for both the driver and the motor carrier. Understanding who is responsible for what is essential, especially for owner-operators who are both the driver and the carrier.
Driver Responsibility
- -Accurately recording all duty status changes
- -Monitoring and complying with all HOS limits
- -Refusing to drive when hours are exhausted
- -Maintaining ELD and paper log backup
- -Fines assessed personally to driver
Carrier Responsibility
- -Not requiring or allowing drivers to exceed HOS
- -Providing compliant ELD devices
- -Monitoring driver logs for compliance
- -Scheduling loads that are achievable within HOS
- -Fines up to $16,000 per violation for coercion
The Coercion Rule Protects Drivers
Falsifying Logs: The Nuclear Option
Record falsification under 49 CFR 395.8(e) is the most serious HOS violation a driver can commit. It carries the highest fines, the most severe CSA impact, and can result in CDL disqualification. With ELD technology, FMCSA has increasingly sophisticated tools to detect falsified records.
What Constitutes Falsification
- - Editing automatically recorded driving time to show off-duty
- - Using a second ELD account or "ghost" driver profile
- - Disconnecting the ELD from the engine ECM while driving
- - Using personal conveyance while loaded or en route to a pickup
- - Instructing another person to log your driving time
- - Operating under another driver's profile
Penalties for Falsification
- - Fines: $2,750 to $16,000+ per violation
- - CDL disqualification: 60 days minimum (first offense)
- - CDL disqualification: 120 days (second offense within 10 years)
- - CSA severity weight: 10 (maximum)
- - Potential criminal prosecution in egregious cases
- - Carrier-level targeted investigation if pattern detected
How to Contest an HOS Violation
Not every citation is correct. Officers make errors, ELD data can be misread, and circumstances sometimes justify what appears to be a violation. You have the right to challenge any HOS violation through the DataQs process.
Review the Violation Report
Obtain the full inspection report from the FMCSA SMS portal. Check every detail: the violation code, the time and location recorded, and the specific regulation cited. Errors in any of these fields can be grounds for a successful challenge.
File a DataQs Request
Submit a Request for Data Review (RDR) through the FMCSA DataQs system at dataqs.fmcsa.dot.gov. Include your ELD records, any supporting documentation (weather reports, shipper receipts, toll records), and a clear explanation of why the violation is incorrect or should be reclassified.
Follow Up and Track
DataQs challenges are reviewed by the state that issued the violation. Response times vary from 30 to 90 days. Track your case through the DataQs portal and provide any additional information requested promptly. If the initial challenge is denied, you can submit an arbitration request.
Preserve Evidence Immediately
Prevention Strategies That Work
The cheapest HOS violation is the one that never happens. These strategies address the root causes of the most common violations:
Check Your Clocks Before Every Departure
Before starting any drive, verify your remaining hours on all five HOS clocks: 11-hour driving, 14-hour window, 30-minute break trigger, weekly hours, and time until restart eligibility. Your ELD displays all of these. Know your numbers before you move.
Build Buffer Time Into Every Trip
If the GPS says the drive takes 6 hours, plan for 7.5. Traffic, construction, weigh stations, and weather add time that your routing app does not account for. Running out of hours 30 minutes from the receiver is not bad luck; it is bad planning.
Communicate Detention Time Early
The 14-hour clock is the most common cause of HOS violations because shipper/receiver wait times consume window time without consuming driving hours. If you are waiting more than 30 minutes, notify dispatch immediately so they can adjust your schedule before you run out of window.
Know Your Exemptions
Familiarize yourself with every HOS exception and exemption you might qualify for. The adverse driving conditions exception gives you 2 extra hours. The split sleeper berth provision lets you pause the 14-hour window. These are legal tools designed for exactly the situations where violations typically occur.
ELD Tamper Detection in 2026
FMCSA and enforcement officers are using increasingly sophisticated methods to detect ELD tampering and log falsification. Understanding what they look for helps you understand why accurate logging is the only safe approach.
Unassigned Driving Time Analysis
Officers check for unassigned vehicle movement periods on your ELD. If the truck moved but no driver was logged in, that is a red flag for log manipulation. Large amounts of unassigned driving time trigger deeper investigation.
GPS vs Log Correlation
ELDs record GPS coordinates at every status change and during driving. Officers cross-reference these coordinates with your reported duty status. If your log shows off-duty but GPS shows the vehicle moved 200 miles, you have a falsification problem.
Edit Pattern Analysis
ELDs record every edit made to the log, including who made the edit and when. A pattern of editing driving time to off-duty status, especially near HOS limits, is a clear indicator of falsification that officers are trained to identify.
How O Trucking LLC Prevents HOS Violations
The best violation prevention starts at the dispatch desk. We build every load plan around your real available hours because a delivered load is worthless if it comes with a violation that costs more than the freight paid.
Hours-Verified Dispatching
Every load assignment is verified against your current HOS status. We check your remaining driving time, window time, break requirement, and weekly hours before accepting any load. If the math does not work, we find a different load that does.
Proactive Violation Monitoring
We review ELD data for potential compliance issues before they become violations at a roadside inspection. If we spot unassigned driving time, missing annotations, or patterns that could trigger enforcement action, we address them with the driver immediately rather than waiting for an officer to find them.
DataQs Support
If one of our carriers receives a violation we believe is incorrect, we help prepare and submit the DataQs challenge. We know what documentation to include, how to frame the argument, and how to follow up with the reviewing state agency. A successful challenge removes the violation from your CSA record.
Avoid Costly HOS Violations
Our compliance-first dispatch team plans every load around your real available hours. No pressure to exceed limits, no temptation to edit logs, and no violations that damage your CSA score for three years.
