Understanding Driver Fatigue and Hours-of-Service Violations in Truck Accidents

Driver fatigue is one of the most dangerous—and most preventable—risks on American highways. When truck drivers push beyond legal limits or fail to rest adequately, the results can be devastating. Fatigue impairs judgment, slows reaction time, and can lead to catastrophic accidents involving massive commercial vehicles.

In this post, we’ll break down the causes of driver fatigue, the federal Hours-of-Service (HOS) regulations designed to prevent it, how violations are uncovered, and what it means for truck accident victims seeking justice.

What Is Driver Fatigue?

Driver fatigue occurs when a truck operator becomes too tired to drive safely due to a lack of sleep, long hours behind the wheel, or irregular schedules. It is especially dangerous for commercial drivers because of the size and weight of the vehicles they operate.

Effects of fatigue on drivers:

• Slowed reaction times

• Poor decision-making

• Decreased focus

• Increased risk of falling asleep at the wheel

According to the Federal Motor Carrier Safety Administration (FMCSA), driver fatigue is a factor in thousands of truck crashes each year—and it’s often entirely avoidable.

Understanding Hours-of-Service (HOS) Regulations

To combat fatigue, the FMCSA has established Hours-of-Service rules, which dictate how long a commercial truck driver can operate their vehicle before taking a break or going off duty.

Key HOS Rules for Property-Carrying Drivers:

1. 11-Hour Driving Limit: Drivers may drive a maximum of 11 hours after 10 consecutive hours off duty.

2. 14-Hour Limit: Drivers may not drive beyond the 14th consecutive hour after coming on duty, following 10 hours off duty.

3. 30-Minute Break Rule: Drivers must take a 30-minute break after 8 cumulative hours of driving time.

4. 60/70-Hour Limit: Drivers may not drive after 60/70 hours on duty in 7/8 consecutive days. A 34-hour restarts the cycle.

Exceptions and Flexibility:

• Short-haul exemptions apply to drivers who operate within a 150-air-mile radius.

• Sleeper berth provision allows drivers to split required rest periods under certain conditions.

These rules are designed to balance efficiency with safety, but they are often ignored or violated under pressure to meet delivery deadlines.

Common Hours-of-Service Violations

Despite the regulations, HOS violations are unfortunately common in the trucking industry. Some of the most frequent violations include:

• Falsifying logbooks or electronic logging devices (ELDs)

• Driving beyond the legal time limits

• Failing to take mandatory rest breaks

• Operating without proper HOS documentation

These violations put everyone on the road at risk and may expose the driver, trucking company, or both to liability.

Why Do HOS Violations Happen?

Several factors contribute to HOS violations, including:

• Pressure from trucking companies to meet tight delivery schedules

• Financial incentives for drivers to deliver faster or take on more miles

• Lack of enforcement or monitoring by carriers

• Unrealistic delivery expectations or poorly planned routes

Even with ELDs now required in most trucks, some companies and drivers still manipulate records or disregard the rules altogether.

How Attorneys Investigate Driver Fatigue and HOS Violations

When investigating a truck accident, a skilled truck accident attorney will examine whether fatigue or HOS violations played a role. This often includes:

Key evidence reviewed:

• Electronic Logging Device (ELD) data: Shows driving hours, rest periods, and on-duty time.

• GPS and dispatch records: May reveal inconsistencies with reported hours.

• Fuel and toll receipts: Help verify the driver’s location and timing.

• Surveillance footage and witness testimony: Can show signs of fatigue or erratic driving behavior.

• Employment and delivery schedules: May suggest overworking or noncompliance.

When violations are uncovered, they strengthen the case against the trucking company and increase the likelihood of a successful claim.

Legal Consequences of HOS Violations in Accident Claims

If an HOS violation or driver fatigue is proven to have caused or contributed to the crash, it can significantly impact the outcome of a personal injury or wrongful death lawsuit.

Potential consequences include:

• Increased liability for the driver and the trucking company

• Higher compensation for victims due to reckless or negligent behavior

• Punitive damages in severe or repeated violation cases

• Regulatory penalties for the trucking company

Proving fatigue can be the difference between a modest settlement and full, fair compensation.
