Understanding what happens after a commercial vehicle accident

This article is intended for educational purposes only, providing general insights into commercial vehicle accidents and related legal topics. It is important to consult a qualified attorney for advice tailored to your specific situation.

Accidents involving commercial vehicles can be life-altering, leaving victims to deal with severe injuries, extensive property damage, and overwhelming legal challenges. These incidents are often more complex than typical motor vehicle accidents, as you face the physical and emotional toll of the crash and the task of standing up to powerful companies and corporations. These organizations can make an already challenging situation feel even more intimidating for those seeking justice because they have well-funded legal teams dedicated to minimizing payouts.

Whether you’re dealing with medical expenses, lost wages, or the emotional toll of a crash, understanding your legal rights is vital. This blog will explore the key aspects of commercial vehicle accidents, from the types of vehicles involved to the parties that may be held accountable, guiding you through the legal process to help you secure fair compensation.

Types of Commercial Vehicles

According to the Federal Motor Carrier Safety Administration (FMCSA), a commercial motor vehicle (CMV) is any vehicle used in interstate commerce for transporting passengers or goods that meets one or more of the following criteria:

  • Weight specifications:
    • A gross vehicle weight rating (GVWR) of 10,001 pounds or more
    • A combination of vehicles with a combined GVWR of 26,001 pounds or more
  • Passenger capacity:
    • Designed to transport more than eight passengers for compensation or 15 passengers without compensation
  • Hazardous materials:

These qualifications distinguish commercial vehicles from non-commercial ones and highlight the heightened risks they pose on the road. Their larger size, heavier weight, and sometimes dangerous cargo make accidents involving them far more devastating than those involving standard passenger cars.

Common Causes of Commercial Vehicle Accidents

The causes of commercial vehicle accidents are complex, often stemming from a combination of driver behavior, corporate practices, and external conditions. These factors frequently overlap, creating dangerous scenarios leading to devastating outcomes.

Driver fatigue

Commercial drivers, particularly truck drivers, must work long hours to meet demanding schedules. Even with federal regulations limiting drive times, some drivers push beyond these limits, resulting in driver fatigue. Fatigue impairs reaction times, decision-making abilities, and overall alertness, making it a leading cause of commercial vehicle accidents.

Road and weather conditions

Challenging road conditions like potholes, poorly marked lanes, and construction zones pose significant risks to large trucks and delivery vans. When combined with adverse weather conditions such as rain, snow, or fog, these factors create hazardous driving situations. Reduced visibility and slippery surfaces heighten the chances of collisions, especially for vehicles with large loads.

Safety violations

Negligence by trucking companies or vehicle owners is another critical factor. Failing to comply with essential safety regulations, such as skipping regular maintenance or improperly loading cargo, often leads to mechanical failures or instability. These violations increase the likelihood of accidents and can result in severe consequences for all involved.

Hazardous materials

Vehicles transporting hazardous materials require strict adherence to federal placarding laws and specialized handling procedures. When these protocols are ignored, accidents involving hazardous materials can escalate quickly, leading to spills, explosions, or widespread environmental and human harm.

Influence of alcohol or drugs

Despite stringent regulations, impaired driving remains a persistent issue among commercial vehicle drivers. The influence of alcohol or drugs severely compromises judgment and control, making accidents far more likely, particularly for vehicles carrying heavy or dangerous cargo.

These factors often result in severe accidents, leading to traumatic brain injuries, spinal cord injuries, and other serious injuries that require extensive medical attention.

Parties That Are Potentially Liable for CMVs

One of the complexities of commercial accidents is identifying all liable parties. These may include:

  • The driver: The actions of the commercial vehicle driver are often the most direct cause of an accident. Negligent behaviors such as speeding, distracted driving, driver fatigue, or operating under the influence of alcohol or drugs can significantly contribute to collisions. In these cases, the driver’s choices or failure to follow safety regulations may make them liable
  • The employer: Employers are responsible for ensuring their operations comply with legal standards. They can be held accountable for their employees’ actions within the employment scope. Additionally, employers may face independent liability for negligence, such as failing to properly train or supervise drivers or neglecting required vehicle inspections and maintenance
  • Vehicle manufacturers: Defective vehicles or faulty parts are another potential cause of commercial accidents. Manufacturers may be liable if design flaws or mechanical issues, such as brake failures or tire blowouts, directly contributed to the crash. Proving manufacturer liability often requires expert analysis of vehicle damage and a detailed review of maintenance and production records
  • Cargo loaders: Improperly loaded or secured cargo is a frequent factor in large truck accidents. If cargo shifts during transit, it can destabilize the vehicle, leading to rollovers or jackknife incidents. Entities responsible for loading and securing the goods can be held liable if their negligence contributed to the crash. This is particularly important when the vehicle is carrying hazardous materials, as improperly handled cargo can exacerbate the accident’s severity

Determining fault involves collecting evidence such as witness statements, maintenance logs, and driver records.

What is vicarious liability?

The legal doctrine of vicarious liability, under respondeat superior, allows employers to be held accountable for their employee’s actions if those actions occur within the scope of their employment. For instance, companies can be liable for accidents caused by drivers performing job-related tasks, such as delivering or transporting goods.

It is important to note that establishing vicarious liability requires clear evidence linking the driver’s actions to their employer’s oversight or directives. Key documentation often includes employment records verifying the driver’s role with the company, delivery schedules or logs proving the driver was actively working, and evidence that the driver followed company instructions during the accident. However, exceptions exist.

Employers may avoid liability if the driver was engaged in personal activities, deviated significantly from their assigned duties, or used the vehicle without authorization. Additionally, companies are typically not responsible for the actions of independent contractors unless they exercise significant control over the contractor’s work. These nuances make understanding and proving vicarious liability critical in commercial vehicle accident cases.

Filing a claim against a trucking company or other corporation after a commercial vehicle accident often places individual claimants at a significant disadvantage. These corporations benefit from extensive resources, including teams of specialized lawyers dedicated to minimizing payouts.

Unlike individual claimants, who may be going through the legal process for the first time, corporate legal teams have extensive experience and expertise in defending their clients, making the claims process challenging for victims.

This imbalance isn’t just about financial resources; it also reflects the corporations’ ability to prolong cases, navigate legal loopholes, and use procedural knowledge to their advantage. While individual claimants are focused on recovering from serious injuries and other damages, corporate legal teams can focus solely on their defense strategies.

Common defense tactics used by corporations

Trucking companies and their legal teams use various defense strategies to minimize liability and reduce compensation in commercial vehicle accident cases. Below are the most common tactics, explained in detail:

  • Comparative negligence: This defense argues that the victim’s actions, such as speeding, distracted driving, or failing to yield, contributed to the accident. By establishing partial fault, the company can reduce the compensation owed based on the victim’s percentage of responsibility
  • Sudden emergency doctrine: Companies claim that the driver faced an unexpected and unavoidable emergency, such as a sudden mechanical failure or an obstacle on the road, which necessitated immediate action. They argue that the driver’s response was reasonable under the circumstances, absolving them of liability
  • Pre-existing conditions: The defendants may argue that the victim's injuries are not from the accident but from prior medical conditions. By pointing to medical records, they aim to shift the blame away from the accident for the injuries in question
  • Parts or equipment malfunctions: Businesses may contend that rather than driver error, the accident resulted from mechanical failures, such as faulty brakes, tires, or other vehicle systems. This defense is often used to involve manufacturers or maintenance providers as additional liable parties
  • Independent contractor defense: To avoid liability, companies claim the driver involved in the accident was an independent contractor, not an employee. This distinction allows them to argue that they do not bear responsibility for the driver’s actions during the incident
  • Weather and road conditions: Defendants may argue that poor weather conditions, such as rain, snow, or fog, or hazardous road conditions, like potholes or construction zones, were the primary cause of the accident and beyond the driver’s control
  • Lack of evidence: Companies challenge the adequacy of the victim’s evidence, such as insufficient accident reports, unclear photos, or missing witness statements, to cast doubt on the claim’s validity and undermine liability
  • Federal Motor Carrier Safety Regulations compliance: Trucking companies may present records demonstrating compliance with FMCSA regulations, such as hours-of-service rules, maintenance schedules, and driver qualifications, to argue that they followed all legal requirements and were not negligent

How personal injury lawyers level the playing field

Personal injury lawyers are essential in helping victims counter the aggressive defense tactics employed by these corporations. These lawyers thoroughly investigate the accident, gathering crucial evidence to build a strong case. They also analyze maintenance logs and driver compliance with federal safety regulations to refute claims like equipment malfunctions or sudden emergency defenses. By identifying all liable parties, including the trucking company and other potentially negligent entities, personal injury lawyers ensure the victim's case is comprehensive and backed by solid evidence.

In addition to building the case, personal injury lawyers handle negotiations with insurance companies, pushing back against low settlement offers and attempts to exploit legal loopholes. They fight to secure compensation for all damages, ensuring the settlement fully reflects the victim’s needs.

As an option, they are prepared to take the case to litigation, ensuring corporations are held accountable. Their expertise helps overcome the power imbalance, allowing you to focus on recovery and obtain the justice you deserve.

The Bottom Line

Dealing with a commercial vehicle accident is never easy and can feel like an uphill battle. Between the physical recovery, emotional toll, and overwhelming legal hurdles, it’s easy to feel outmatched—especially when going up against well-funded companies that know how to protect their bottom line.
