Guide to 18-Wheeler Accidents: Lawyer’s Role & Liability


Updated on:


18-wheeler accidents are a serious issue on roads and highways due to the significant size and weight of these commercial trucks, and seeking legal guidance after such accidents is critically important.  

18-wheeler accidents can often result in catastrophic injuries or even loss of life due to the massive weight and momentum of these large vehicles weighing upwards of 80,000 pounds fully loaded. 

When a passenger vehicle collides with a commercial truck, the physics of the crash greatly favors the truck due to its substantial mass. 

As a result, injuries from 18-wheeler accidents tend to be more severe. It is therefore essential for anyone involved in an 18-wheeler accident to promptly seek legal counsel from an experienced truck accident attorney. 

A truck accident lawyer can thoroughly investigate the crash and determine liability to help maximize compensation for medical bills, lost wages, pain, and suffering. 

They understand commercial vehicle regulations and can establish if the driver or carrier was negligent.


Understanding 18-Wheeler Accidents

An 18-wheeler accident refers to any vehicle collision involving a large commercial truck, also called an articulated lorry, tractor-trailer, or semi-trailer truck. 

These trucks have a cab section and one or more trailers, with a combined total of 18 wheels (hence the name). They are typically more than 30 feet long and can weigh up to 80,000 pounds when fully loaded. 

Given their massive size and weight, 18-wheeler accidents often cause catastrophic damage and serious injuries. 

Common scenarios leading to 18-wheeler accidents include unsafe lane changes, sudden braking, excessive speed, driver fatigue or impairment, and faulty equipment.

Statistics and Common Scenarios Leading to These Accidents

Government statistics reveal that around 100,000 people are injured annually in accidents involving large trucks across America. 

On average, there are over 4,000 fatal 18-wheeler accidents every year. 18-wheelers, despite representing just 3% of vehicles on the road, account for around 10% of vehicle accident fatalities. 

Some studies suggest truck drivers frequently exceed safe work hour limits, which can significantly increase crash risk due to fatigue.

Other research shows poor safety records and violations are widespread among certain trucking companies. 

This underscores why experienced legal counsel is crucial after an 18-wheeler collision.

Main Causes of 18-Wheeler Accidents

Driver Negligence and Fatigue.

Driver negligence and fatigue are substantial factors in many 18-wheeler accidents each year. Commercial truck drivers often have to meet tight schedules which can encourage risky driving behaviors and prolonged time behind the wheel. 

Speeding of truck

Fatigue severely impairs alertness and reaction time. When truckers ignore safety regulations limiting work hours, it greatly elevates the probability of an accident occurring due to drowsiness. 

Aggressive driving, speeding, drifting between lanes without signaling, and other negligent behaviors put the lives of everyone sharing the road at risk. 

A driver’s prior safety record and citations should be investigated after any collision involving a large rig.

Vehicle Maintenance Issues and Mechanical Failures

Vehicle maintenance issues and mechanical defects are another preventable primary cause of 18-wheeler accidents. 

Problems such as brake or tire failures, jackknife events from faulty components, and other technical problems that arise from poor inspections and repairs by motor carriers endanger innocent people. 

Regular pre-trip and post-trip inspections are crucial to identify any potential issues before operating dangerous equipment on public roadways. 

Subpar maintenance demonstrates negligence on the part of trucking companies. A thorough examination of vehicle data and service records can help show whether equipment played a role in a particular crash.

External Factors Like Road Conditions and Weather

External environmental factors can also substantially contribute to and exacerbate the consequences of 18-wheeler accidents. 

Adverse conditions like rainy or icy roadways, fog, construction zones, narrow shoulders, steep grades, and other challenges posed by infrastructure design, debris, or traffic flows combine with 80,000-pound trucks to heighten crash risks. 

A full investigation of the scene, vehicle, and driver is important to determine if any external causes should lessen liability and where responsibility ultimately lies after an accident occurs involving a large commercial motor vehicle.

Determining Fault and Responsible Parties

Determining fault and the responsible parties in 18-wheeler accidents is essential to receiving appropriate compensation. 

A thorough investigation considers factors like speed, vehicle condition, driving records, and road conditions.

Accident reconstruction helps establish the events leading up to the crash. Evidence could show the truck driver was negligent through actions like speeding, distracted driving, or neglecting to follow safety procedures. 

The motor carrier may be at fault if they fail to properly train, screen, or supervise drivers. Federal regulations hold trucking companies responsible for maintaining vehicles and ensuring drivers safely operate them.

Role of Trucking Companies and Their Responsibilities

Trucking companies play a vital role in 18-wheeler accidents through their responsibility for properly training and supervising drivers, complying with regulations, and maintaining commercial vehicles. 

They must ensure drivers follow all relevant safety rules regarding issues like work hours, logbooks, speed limits, and pre-trip inspections. 

Motor carriers are also accountable if they hire or retain drivers with poor prior safety records. Negligent hiring, training, and oversight can open the door for third-party liability claims.

Potential Third-party Liabilities in These Accidents

Potential third parties may also bear liability in 18-wheeler accidents. This includes manufacturers if a mechanical defect caused or contributed to a collision. 

Road crews or governmental agencies could be partially at fault for inadequate signage, barriers, or road design that set the stage for an accident. 

Establishing responsibility among all potentially liable third parties is important for fully compensating victims of commercial truck crashes.

Importance of Hiring an 18-Wheeler Accident Lawyer

Advantages of Having Legal Representation

Here are the following advantages of legal representation:

  • Thoroughly investigate the cause of the accident and identify who may be at fault.
  • Determine if there were any violations of safety regulations or negligence.
  • Maximize the compensation by demonstrating the full value of losses.
  • Handle all communications with insurance companies on your behalf.
  • Advocate for the victim during legal proceedings and settlement negotiations.

How a Lawyer Can Navigate Complex Legal Procedures

Navigating the legal process after an 18-wheeler accident can be challenging. An experienced accident lawyer understands the complexities involved such as commercial vehicle regulations, accident reconstruction procedures, insurance law, and liability determinations specific to these types of serious crashes. 

They know the intricacies of proving responsibility for those at fault, whether it’s negligent driving, unsafe vehicles, lack of proper maintenance records, or other causes. 

With their expertise in handling similar cases, an 18-wheeler accident attorney can efficiently guide victims through the litigation and help achieve the optimal outcome.

Ensuring Victims’ Rights are Protected and Upheld

Victims of 18-wheeler accidents must protect their legal rights and ensure they are properly compensated for medical bills, lost income, pain and suffering, or even wrongful death. 

An attorney dedicates their time and expertise exclusively to these types of cases. They will make certain clients’ medical needs are met as the litigation unfolds. 

A lawyer also safeguards the interests of the injured as insurance providers typically aim to settle for lower amounts. 

Their advocacy is essential for upholding victims’ rights in seeking full and fair remedies under the law.

Inattention to Blind Spots

What an 18-Wheeler Accident Lawyer Does

Investigating the Accident Scene and Gathering Evidence

In the aftermath of 18-wheeler accidents, experienced lawyers immediately get to work investigating the crash scene and preserving evidence. 

They analyze details like skid marks, vehicle damage, and road conditions and may hire accident reconstruction experts. 

By pinpointing exactly what occurred, attorneys are better equipped to determine if negligence or safety violations caused or contributed to the collision. 

Gathering records regarding the truck, driver, and carrier is also key. A lawyer ensures potentially liable parties don’t destroy important documentation and that victims’ legal rights are protected.

Negotiating with Insurance Companies and Opposing Parties

Representing clients skillfully in negotiations with insurance providers is another vital role for 18-wheeler accident lawyers. 

They leverage investigative findings to argue the full extent of losses should be covered. When carriers aim to undervalue claims, attorneys know to justify higher settlement amounts based on regulations, case law, and each client’s unique circumstances.
