Fatigued driving is one of the most dangerous and preventable causes of serious truck accidents. To combat this, the FMCSA created hours-of-service (HOS) rules, limiting how long commercial drivers can be on the road.
HOS violations are still common and can lead to severe injuries, fatalities, and consequences beyond fines. In truck accident cases, these violations affect how fault and negligence are assigned. Texas truck accident lawyers use HOS violations to show risky driving, spot trucking company problems, and help claims.
At Farah Law, we show how HOS violations prove negligence, hold trucking companies responsible, and affect your payout. We help preserve critical evidence and protect your rights after fatigue-related crashes, ensuring your claim is as strong as possible.
What FMCSA Hours-of-Service Rules Require
FMCSA hours-of-service (HOS) rules are federal laws that keep truck drivers rested and alert on the road. These rules apply to most drivers of trucks over 10,000 pounds that travel across state lines. Many Texas-based carriers must also follow these rules.
For drivers hauling property, the main rules include:
- 11-hour driving limit after 10 straight hours off duty
- 14-hour workday limit, which keeps running even during breaks
- 30-minute break after eight total hours of driving
- 60- or 70-hour weekly limits, depending on the driver’s schedule
To track these limits, most trucks use electronic logging devices (ELDs). ELDs record when the truck is moving, how long it drives, and where it goes. While this system makes manipulation harder, it does not stop it completely. Some drivers or companies still try to bend the rules by claiming exceptions that do not apply. Whether an exemption is valid is often a legal question that must be closely examined.

Why Hours-of-Service Violations Matter in Truck Accident Cases
Driving while tired greatly increases the risk of a crash. Fatigue slows reaction time, affects judgment, and reduces awareness. It can also cause microsleeps, which are brief moments when a driver unintentionally falls asleep. Even a few seconds of inattention can lead to a serious collision.
In truck accident cases, HOS violations strengthen the case more than in a typical car accident claim. Instead of arguing over simple mistakes, the focus shifts to whether a professional driver followed clear safety rules. When a driver breaks these rules, it shows a failure to meet required safety standards.
HOS violations can also expose trucking companies to more liability. Fatigue often results from tight schedules, unrealistic delivery demands, or employer pressure. Demonstrating an HOS violation helps link the driver’s exhaustion to the company’s role in creating unsafe conditions.
How FMCSA Violations Establish Negligence or Negligence Per Se
In most traffic accidents, the injured person must prove that the other driver acted carelessly. But when a truck driver violates an HOS rule, lawyers may rely on a legal doctrine called negligence per se. This means breaking a safety law meant to prevent harm can automatically count as negligence.
HOS rules are not suggestions. They are mandatory limits based on research showing how fatigue causes crashes. These rules exist to protect everyone on the road, especially from large trucks that can cause devastating damage.
Even when an injured party proves an HOS violation, they must still show that fatigue played a role in the crash. Defense lawyers often claim the accident was caused by something else, like traffic or another driver. A strong legal strategy focuses on showing how fatigue affected the truck driver’s ability to react, see hazards, or avoid the collision.

Evidence Used to Prove Hours-of-Service Violations
Proving an HOS violation usually requires reviewing several types of records. Common evidence includes:
- ELD data and activity records
- Driver logbooks and trip reports
- Fuel receipts, toll records, and GPS data
- Dispatch messages and delivery schedules
- Statements made by the driver after the crash
Trucking companies rarely provide this information willingly. When records do not line up, it may show that logs were falsified or that the driver could not have legally made the trip. If records are missing or destroyed, lawyers can use subpoenas and spoliation letters to make sure the evidence is saved and shared.
Trucking Company Liability for Hours-of-Service Violations
Trucking companies are usually responsible for their drivers’ actions while on the job. HOS violations can also be used to hold the company responsible for poor supervision, training, or scheduling. Company liability often comes from practices such as:
- Setting delivery deadlines that require illegal driving hours
- Ignoring known log violations
- Rewarding drivers for driving longer or faster
- Repeated failures to follow safety rules
Repeated violations may indicate a company-wide problem. In serious cases, this can support claims for punitive, or exemplary, damages under Texas law.
How Hours-of-Service Violations Affect Comparative Fault
Texas follows a modified comparative fault rule. If a judge or jury finds an injured person to be more than 50% responsible for a crash, they cannot recover damages. Insurance companies often try to blame the injured driver to reduce what they have to pay.
HOS violations make it harder for insurers to blame the injured driver. If a truck driver was breaking the rules, it is less believable that the victim caused the crash. Showing that fatigue played a role can significantly increase the compensation.
Impact of Hours-of-Service Violations on Settlement Value
Proven HOS violations often increase the value of a truck accident claim. Insurance companies know that juries react strongly to evidence of fatigued driving and safety rule violations. These cases carry higher risk for trucking companies because:
- Defenses are harder to support
- Punitive damages may be possible
- Juries closely examine company safety practices
Clear evidence of violations can lead to faster and larger settlements.
When to Hire a Lawyer for a Truck Accident Involving HOS Violations
Signs of HOS violations include late-night crashes, drifting out of lanes, not braking, conflicting driver statements, or slow record sharing. It’s important to act fast because some records can be lost.
A truck accident lawyer can help get evidence, find fake logs, and protect your claim. If fatigue or hours-of-service violations caused your crash, Farah Law can help protect your evidence and get full compensation.
