Hours of Service Violations: How Truck Driver Fatigue Can Cause Serious Wrecks

Commercial truck drivers play a critical role in keeping goods moving across the country. However, the demands of the trucking industry can sometimes lead drivers and trucking companies to prioritize deadlines over safety. One of the most common causes of serious truck wrecks is a violation of the Federal Motor Carrier Safety Administration’s (FMCSA) Hours of Service (HOS) regulations.

Understanding these rules—and what happens when they are violated—can help accident victims recognize when negligence may have contributed to a crash.

What Are Hours of Service Regulations?

Hours of Service regulations are federal rules designed to prevent driver fatigue. The FMCSA established these requirements to limit the number of hours a commercial truck driver can operate a vehicle before taking mandatory rest breaks.

Key Hours of Service rules for property-carrying drivers generally include:

An 11-hour driving limit after 10 consecutive hours off duty.
A 14-hour on-duty limit, which restricts driving beyond the 14th consecutive hour after coming on duty.
A 30-minute break requirement after driving for a specified period.
A 60/70-hour limit that restricts the total number of hours a driver may be on duty during a seven- or eight-day period.

These regulations are intended to reduce the risk of fatigue-related crashes and protect everyone sharing the road with commercial vehicles. A useful summary is found here.

Why Driver Fatigue Is So Dangerous

Fatigue affects a driver’s ability to react, make decisions, and maintain focus. Research has shown that sleep deprivation can impair performance in ways similar to alcohol intoxication.

When a truck driver is exhausted, they may experience:

Slower reaction times
Difficulty maintaining lane position
Reduced awareness of traffic conditions
Impaired judgment
Increased risk of falling asleep behind the wheel

Because commercial trucks can weigh up to 80,000 pounds when fully loaded, even a momentary lapse in attention can have devastating consequences.

Common Hours of Service Violations

Unfortunately, Hours of Service violations occur more often than many people realize. Some common examples include:

Exceeding Maximum Driving Hours

Drivers may continue driving beyond legal limits to meet delivery schedules or increase earnings.

Falsifying Logbooks

Although electronic logging devices (ELDs) have made recordkeeping more accurate, some drivers and companies still attempt to manipulate records to conceal violations. There are even carriers using “Ghost Drivers” to get around the hours of service requirements.

Skipping Required Rest Breaks

Drivers may forgo required breaks in an effort to stay on schedule, leading to increased fatigue over time.

Pressuring Drivers to Meet Unrealistic Deadlines

In some cases, trucking companies may create expectations that encourage drivers to violate federal regulations.

How Hours of Service Violations Contribute to Truck Accidents

A fatigued truck driver may be unable to react quickly to changing traffic conditions. As a result, Hours of Service violations can contribute to:

Rear-end collisions
Lane departure accidents
Jackknife crashes
Rollover accidents
Multi-vehicle pileups

Investigators often review driver logs, electronic data, dispatch records, GPS information, and other evidence to determine whether fatigue or HOS violations played a role in a crash.

Proving an Hours of Service Violation After a Truck Wreck

Evidence of a violation is not always obvious. An experienced truck accident attorney may investigate:

Electronic logging device data
Driver qualification files
Fuel receipts
Toll records
GPS tracking information
Dispatch communications
Cell phone records
Maintenance records

These documents can reveal inconsistencies and help establish whether a driver exceeded allowable operating hours.

Who Can Be Held Liable?

Liability may extend beyond the truck driver. Depending on the circumstances, responsible parties may include:

The truck driver
The trucking company
A motor carrier
A logistics company
A shipper
Other entities involved in supervising or scheduling transportation operations

A thorough investigation is often necessary to identify all potentially liable parties.

What Accident Victims Should Do

If you have been injured in a collision involving a commercial truck, it is important to act quickly. Evidence related to Hours of Service compliance may be lost or destroyed if it is not preserved.

Accident victims should:

Seek medical treatment immediately, if needed.
Document the accident and their injuries.
Avoid discussing fault with insurance representatives.
Consult an experienced truck accident attorney as soon as possible.
