When a truck driver causes an accident, hours of service violations often play an important role in determining who is legally responsible. The Federal Motor Carrier Safety Administration (FMCSA) sets rules about how many hours drivers can spend behind the wheel to reduce driver fatigue, a common factor in serious truck crashes. If a driver violates these rules and causes a collision, that violation can support a negligence claim. Understanding how these violations work and how they can help show negligence may improve your chances of recovering compensation after a truck accident in Arizona.

Understanding Federal Hours of Service Regulations
The FMCSA establishes hours of service (HOS) regulations that most interstate commercial truck drivers must follow. These rules limit how long drivers can operate a vehicle and require specific off‑duty and rest periods. In an Arizona truck accident case, evidence that a driver violated these regulations can be used to support a claim that the driver was not operating the vehicle safely.
The 11‑Hour Driving Limit
Under current FMCSA rules for property‑carrying drivers, a driver may drive up to 11 hours after taking 10 consecutive hours off duty. After reaching 11 hours of driving, the driver must be off duty long enough to obtain another 10 consecutive hours off before driving again. Exceeding this limit can be evidence that a driver remained on the road when they should have been resting.
The 14‑Hour On‑Duty Window
Drivers generally may not drive beyond the 14th consecutive hour after coming on duty following 10 consecutive hours off duty. This 14‑hour window includes all on‑duty time, such as driving, loading and unloading, and inspections, and off‑duty breaks do not extend the 14‑hour limit. Once that window closes, the driver cannot legally continue driving until they have reset with the required off‑duty time.
The 30‑Minute Break Requirement
After a driver has accumulated 8 hours of driving time without at least a 30‑minute interruption, they must take a break of at least 30 consecutive minutes. This break can usually be satisfied by time spent off duty, in the sleeper berth, or on duty but not driving, depending on how the rule is applied in a given situation. The purpose of this requirement is to reduce driver fatigue during longer driving periods.
Weekly 60/70‑Hour Limits
HOS rules also limit how many hours a driver can be on duty over a 7‑ or 8‑day period. A driver may not drive after being on duty 60 hours in any 7 consecutive days or 70 hours in any 8 consecutive days, depending on the carrier’s schedule. Drivers may restart their 7‑ or 8‑day period by taking at least 34 consecutive hours off duty. These weekly limits are designed to prevent cumulative fatigue.
Arizona generally follows these federal hours of service rules for most commercial truck drivers operating in the state.
How Hours of Service Violations Help Establish Negligence
Hours of service violations can be significant in an injury case because they show that a driver failed to follow safety rules meant to protect the public. When a driver violates FMCSA regulations and a crash occurs, that violation can be strong evidence that the driver breached their duty to operate the truck safely.
In some situations, a violation of a safety statute or regulation can support a “negligence per se” theory, meaning the violation itself can serve as evidence of negligence if certain conditions are met. Whether negligence per se applies in a particular Arizona case depends on the facts and applicable law, so your attorney will analyze that issue.
Driver fatigue is a common consequence of HOS violations. Drivers who exceed allowable driving hours or skip required breaks tend to have slower reaction times, impaired judgment, and reduced alertness. These factors increase the risk of rear‑end crashes, lane departures, and other serious collisions. Showing that a driver violated HOS rules and then caused a crash can help connect the safety violation to the collision.
Trucking companies can also face liability when hours of service rules are violated. If a carrier pressures drivers to meet unreasonable schedules, fails to monitor driver hours, or ignores obvious non‑compliance, those actions can support claims of negligent supervision, training, or hiring. Carriers are expected to have systems in place to promote compliance with FMCSA rules; failing to do so can expose the company to additional responsibility.
Common Types of Hours of Service Violations
Some of the more frequent ways HOS rules are broken include:
- Driving beyond 11 hours of permitted driving time without the required 10‑hour off‑duty period.
- Continuing to drive after the 14‑hour on‑duty window has expired.
- Failing to take the required 30‑minute break after 8 hours of driving.
- Exceeding the 60/70‑hour weekly limits over 7 or 8 consecutive days.
- Not taking an appropriate 34‑hour off‑duty restart when required.
- Falsifying or altering electronic logging device (ELD) data or paper logbooks to conceal long hours.
- Dispatch or management practices that result in drivers feeling pressured to keep driving even when they should be resting.
Each of these violations can contribute to driver fatigue and may be carefully scrutinized in a serious crash investigation.
Evidence Used to Prove HOS Violations
Proving hours of service violations typically requires collection and analysis of several different types of records. In a truck accident case, attorneys often pursue:
- Electronic logging device (ELD) data: Most modern commercial trucks use ELDs that automatically track drive time and can provide detailed records of when the truck was moving and when it was stopped.
- Driver logbooks and time records: Where paper or back‑up logs are still kept, they can be compared against ELD and other data to identify discrepancies.
- Bills of lading, shipping documents, and delivery receipts: These show pickup and delivery times and locations, which can be matched to claimed hours to see whether schedules were realistic.
- GPS and telematics data: Fleet management systems, onboard computers, and third‑party GPS services can offer additional information about the truck’s movements and timelines.
- Cellphone and communication records: Calls, texts, and messages with dispatch can corroborate when the driver was on duty and what instructions they received.
- Company policies and emails: Internal dispatch notes, safety policies, and supervisory communications can shed light on how closely the company monitored hours and whether it discouraged or tolerated violations.
- Witness testimony: Drivers, co‑drivers, dispatchers, and other employees may provide insight into common practices and expectations regarding HOS compliance.
Triumph Law Group works to obtain and preserve this evidence quickly in truck accident cases and may collaborate with accident reconstruction and trucking‑industry professionals to interpret the data and explain how it relates to driver fatigue and fault.
Arizona’s Comparative Negligence Law and Truck Accidents
Arizona applies a pure comparative negligence standard in most personal injury cases. This means you may still recover compensation even if you were partly at fault, but your recovery is reduced by your percentage of fault. For example, if your total damages are valued at $200,000 and you are found 25% responsible, your net recovery could be reduced to $150,000.
Evidence of HOS violations can be especially important under comparative negligence. If a truck driver violated federal safety rules and that violation contributed to the crash, that evidence can increase the share of fault attributed to the driver and trucking company, even if another driver made an error as well. In many truck cases, multiple parties may share responsibility, including the driver, the motor carrier, and sometimes brokers, shippers, or maintenance providers, depending on the facts. Identifying and pursuing all potentially liable parties can increase the total insurance coverage available to injured people.
Frequently Asked Questions
What is the FMCSA and why do its regulations matter?
The Federal Motor Carrier Safety Administration is a federal agency within the U.S. Department of Transportation that oversees much of the commercial trucking industry. It issues safety regulations, including HOS rules, that interstate carriers and drivers must follow. These regulations matter because they set minimum safety standards. Violations can be cited in enforcement actions and can also be used as evidence of unsafe operation in civil injury lawsuits.
Can I sue a trucking company directly for HOS violations?
In many cases, yes. Trucking companies may be held responsible on several grounds, including vicarious liability for their drivers’ negligence and direct liability for their own conduct, such as negligent hiring, training, supervision, or retention. If a company fails to monitor driver hours, ignores obvious violations, or pushes drivers to meet schedules that conflict with HOS rules, that evidence can support claims against the company.
How long do I have to file a truck accident claim in Arizona?
For most personal injury cases in Arizona, including truck accidents, the general statute of limitations is two years from the date of the accident, although there are exceptions and special rules in some situations. Because evidence like ELD data and company records can be altered or destroyed over time, it is important to contact an attorney promptly after a crash so preservation letters can be sent and deadlines can be identified.
What damages can I recover in a truck accident case?
Depending on the facts of your case, you may seek compensation for medical expenses (past and future), lost wages, reduced earning capacity, property damage, and non‑economic losses such as pain and suffering, emotional distress, and loss of enjoyment of life. In severe injury or wrongful death cases, total damages can be substantial, but every case depends on its own evidence and the available insurance coverage.
How do you investigate hours of service violations?
In a typical case, Triumph Law Group works to promptly send preservation requests, obtain ELD and GPS data, collect logbooks and company records, and obtain bills of lading and delivery timestamps. The firm may also work with reconstruction professionals and trucking‑industry consultants to compare timelines, speeds, and duty periods to the applicable HOS rules. Witnesses such as drivers and dispatchers may be deposed to clarify day‑to‑day practices and expectations.
What if the driver’s logbook doesn’t match the ELD data?
Discrepancies between a driver’s logbook and ELD or other electronic data can strongly suggest that records were altered or inaccurately kept. This kind of mismatch can be powerful evidence that HOS rules were not followed and that someone attempted to hide the violation. In some cases, such conduct may support requests for enhanced or punitive damages if Arizona law and the facts support that remedy.
