How Hours-of-Service Violations by Truck Drivers Lead to Serious Crashes in Florida

Florida Truck Accident Lawyers Explain Fatigued Driving and Who Is Liable

When a commercial truck crashes into a passenger vehicle on I-95 or the Florida Turnpike, the weight difference alone makes the outcome devastating. But when a truck accident happens because the driver had been behind the wheel for 15 hours straight - long past what federal law permits - the tragedy is compounded by a documented failure that should never have been allowed to happen. Truck accident fatigue is one of the most preventable causes of serious crashes in Florida, and it is one of the most actionable.

The Federal Motor Carrier Safety Administration (FMCSA) sets strict limits on how long commercial truck drivers can drive before they must rest. Many of these rules can be found in the Code of Federal Regulations (CFR), specifically under 49 CFR Part 395. These hours-of-service (HOS) rules exist for one reason: to keep tired truck drivers off the road. When a driver or a trucking company violates these rules and a crash results, those violations become powerful evidence of negligence (the failure to meet the legal standard of care owed to other people on the road).

At The Law Offices of Casey D. Shomo, P.A., our Florida truck accident lawyers investigate HOS violations in serious truck crash cases throughout Palm Beach Gardens, West Palm Beach and across the state. With more than thirty years of experience and millions of dollars recovered for Florida injury victims, Casey D. Shomo and his team know how to obtain the records that prove a fatigued driver should never have been on the road, and how to use those records to build the strongest possible case for our clients.

What Are the FMCSA’s Hours-of-Service Regulations for Truck Drivers?

Understanding what the HOS regulations actually require matters for an injury claim because a violation of these rules is evidence that the driver failed to meet the legal standard of care. The Federal Motor Carrier Safety Administration (FMCSA)’s hours-of-service (HOS) rules under 49 CFR Part 395 set the maximum hours a property-carrying commercial truck driver can work before mandatory rest is required.

The core limits are specific. A driver may not operate a commercial motor vehicle for more than 11 hours after taking 10 consecutive hours off duty. Regardless of how many driving hours remain, a driver cannot operate at all once they have been on duty for 14 consecutive hours from the time they came on shift - this is the 14-hour window rule. Drivers must also take a 30-minute break after eight cumulative hours of driving before continuing.

Beyond the daily limits, weekly limits cap total accumulated hours. A driver cannot exceed 60 hours on duty over seven consecutive days, or 70 hours over eight consecutive days. A 34-hour restart provision allows drivers to reset their weekly cycle after taking at least 34 consecutive hours off duty. These limits exist precisely because the research documenting the relationship between commercial driver fatigue and crash risk is overwhelming and well-established.

What Are the Most Common Hours-of-Service Violations in Florida Truck Accident Cases?

HOS violations come in many forms. Some are the result of deliberate falsification. Others arise from dispatch schedules that make legal compliance practically impossible. These are the violations that appear most often in serious Florida truck accident claims and that generate the strongest evidence of negligence.

• Exceeding the 11-hour driving limit - Driving beyond 11 hours after a 10-hour off-duty period is one of the most straightforward violations. ELD records show exactly when the engine was running and for how long, making this violation difficult to conceal.
• Violating the 14-hour on-duty window - Even if a driver has not used all 11 driving hours, once 14 hours have passed since they came on duty they must stop. Delays at loading docks, traffic and dispatch pressure routinely push drivers past this limit.
• Skipping the mandatory 30-minute break - Drivers must take a 30-minute break after eight cumulative hours of driving. This violation is common when drivers are pressed for time and reflects a deliberate choice to push through fatigue rather than rest.
• Exceeding weekly cycle limits - Violations of the 60 or 70-hour weekly limits only become visible when records are reviewed across the full cycle period. A pattern of cycle violations suggests the carrier’s scheduling practices make legal compliance impossible.
• Falsifying paper logbooks - Before ELDs were required, paper logs were routinely altered to conceal violations. Carriers that were exempt from the ELD mandate or that relied on paper logs prior to the mandate may have records showing falsification inconsistent with GPS or fuel data.
• Tampering with or disabling ELD devices - Some drivers and carriers attempt to manipulate ELD data by unplugging devices, driving with known ELD malfunctions, or using technical workarounds to suppress recorded driving time. These manipulation patterns are often detectable in the data itself.

A single violation in isolation might suggest an isolated lapse. A pattern of violations across multiple drivers or multiple weeks suggests that the company itself is responsible for creating conditions that make compliance with the law impossible. When that pattern exists, the carrier can be held responsible for its own conduct, not just for the driver’s actions.

How Do Hours-of-Service Violations Cause Serious Florida Truck Crashes?

The connection between HOS violations and serious crashes is not a legal theory - it is established science. Extended wakefulness degrades a driver’s reaction time, judgment, situational awareness and ability to process sudden changes in traffic conditions in ways that are measurable and well-documented. The FMCSA’s own research identifies driver fatigue as a factor in a significant percentage of commercial vehicle crashes nationwide.

At highway speed, the difference between a rested driver and a fatigued driver can mean the difference between a near-miss and a catastrophic collision. A truck driver who has been on duty for 16 hours is not simply tired in the ordinary sense - they are operating with cognitive impairment comparable to significant sleep deprivation. When that driver drifts into an adjacent lane, fails to brake in time for slowing traffic or falls briefly asleep at the wheel of an 80,000-pound vehicle, the vehicles around them have almost no chance.

What makes HOS violation cases particularly strong from a legal standpoint is that the regulatory framework itself establishes what is the required standard of care. A driver who exceeded their permitted hours was not just careless in a general sense - they were operating in direct violation of federal rules that exist specifically to prevent the kind of fatigue that causes crashes. That violation, combined with evidence of a resulting crash and serious injuries, forms the foundation of a legally actionable negligence claim against the driver and the carrier.

What Evidence Proves Hours-of-Service Violations in a Florida Truck Accident Case?

Building an HOS violation case requires specific evidence that goes well beyond the police report. Most of that evidence is in the possession of the trucking company, which is exactly why moving quickly after the crash is so important. These are the categories of evidence that matter most.

• Electronic logging device (ELD) data - ELD records show every hour the truck’s engine was running, when it stopped, and the driver’s recorded duty status across the full duty cycle. This data is difficult to alter and provides an objective timeline of the driver’s hours in the days leading up to the crash.
• Driver records of duty status (RODS) - Whether electronic or paper, these logs document hours worked, rest periods taken and duty status over the preceding 14 days. Gaps, inconsistencies or alterations in these records can themselves be evidence of an attempt to conceal violations.
• GPS and vehicle telematics data - GPS records track the truck’s location, speed and movement over time. When compared to the driver’s duty status logs, GPS data can reveal discrepancies - such as a truck in motion during a period the driver claimed to be resting.
• Fuel and delivery records - Fuel purchase timestamps, delivery confirmation records and loading dock receipts independently establish where the driver was and when, providing verification of the actual schedule regardless of what the logbook shows.
• Dispatch records and carrier communications - Texts, emails and dispatch instructions can show whether the carrier was assigning loads that made HOS compliance impossible, or whether dispatchers knew the driver was over their hours and sent them out regardless.
• The carrier’s safety record - A carrier’s history of prior HOS violations, failed roadside inspections and driver fatigue-related incidents can support the argument that the company knew about systemic compliance problems and failed to address them.

This evidence can disappear quickly. ELD data is retained for limited periods. Paper records are routinely destroyed. Dispatch communications are deleted. Our team acts immediately after a serious truck crash to demand preservation of all relevant records - and when necessary, to seek a court order if the carrier resists. Waiting weeks or months to begin this process can permanently compromise the strength of the claim.

Can the Trucking Company Be Held Liable for a Driver’s Hours-of-Service Violations?

Liability is a legal term that refers to who’s legally responsible for paying for an accident when negligence occurs. And in cases involving Hours-of-Service (HOS) violations, the trucking company can often be held liable and forced to pay for financial losses caused by the collision. This is especially true if the trucking company forced the truck driver to violate HOS rules under 49 CFR Part 395. And even if the company didn’t force the truck driver to work long hours, the trucking company has a legal obligation to make sure that its drivers comply with these rules.

Carrier liability arises in several ways. When a company sets delivery schedules that cannot realistically be met without violating HOS limits, dispatches a driver who has already exhausted their available hours, fails to review ELD data that would have revealed ongoing violations or creates a workplace culture in which drivers feel they cannot take required rest without losing assignments, the carrier’s own conduct becomes an independent basis for liability. This is separate from and in addition to the company's potential vicarious liability for the driver's conduct.

This dual liability structure is one of the most important features of a serious HOS violation case. Trucking companies carry commercial insurance policies with limits far higher than what a driver’s personal coverage would provide. When the evidence shows the company itself was at fault for creating or permitting the conditions that put a fatigued driver on the road, the claim against that commercial policy is stronger and more difficult for the insurer to minimize.

What Happens When a Trucking Company Refuses to Produce HOS Records?

It’s common for trucking companies and their insurers to resist producing ELD data, logbooks and internal communications after a serious crash. They understand what this evidence shows, and they deploy experienced legal teams whose job is to limit what reaches the injured person’s legal team. An injured person without legal representation is unlikely to know what records exist, how to demand them or what tools are available when a carrier refuses to cooperate.

A lawyer who is involved from the beginning can issue a formal litigation hold notice requiring the carrier to preserve all relevant records immediately. Federal regulations require carriers to retain certain HOS records for specific periods. Once a preservation demand is made, a carrier that destroys those records faces serious legal consequences - including the possibility that a court will instruct a jury to draw an adverse inference, meaning the jury may assume the missing records would have confirmed the violations the injured person alleged.

This is one of the most important reasons to contact a Florida truck accident lawyer as early as possible after a serious crash. The sooner preservation demands go out, the more difficult it becomes for a carrier to claim that critical records were routinely destroyed before the legal process began. Every day that passes without a formal demand is a day in which evidence can legitimately disappear.

What Compensation Is Available to Florida Victims of Fatigued Truck Driver Crashes?

Florida law allows people seriously injured by a negligent truck driver and carrier to pursue compensation for the full scope of losses the crash caused. Because commercial truck accidents produce severe injuries and commercial carriers carry substantial insurance, these cases often involve compensation far beyond what a standard car accident claim would produce.

• Medical expenses - Emergency treatment, hospitalization, surgery, specialist care, rehabilitation, physical therapy and any future medical needs arising from the injuries sustained.
• Lost income - Wages lost during recovery, including future earning capacity if the injuries permanently prevent the victim from returning to their prior occupation or level of employment.
• Pain and suffering - Compensation for the physical pain, emotional trauma and lasting impact on quality of life caused by serious truck accident injuries. Florida law permits these damages for injuries meeting the serious injury threshold.
• Future care costs - When injuries require ongoing treatment, home modifications or long-term support, those projected future costs are part of the full compensation picture.
• Wrongful death damages - When a fatigued truck driver causes a fatal crash, surviving family members can pursue compensation (damages) in a wrongful death claim for a wide range of financial losses, including funeral expenses, loss of financial support and the loss of care and companionship the deceased would have provided.

The value of an HOS violation claim depends on the severity of the injuries, the strength of the evidence and whether the trucking company’s own conduct contributed to the violation. Identifying every available insurance policy - including excess and umbrella coverage - is an important part of ensuring the claim captures the full compensation available.
