Common Causes of Truck Accidents and Determining Liability

Uncovering the 'Why': Investigating Truck Accident Causes and Liability

Commercial truck accidents are rarely simple events. They often result from a complex combination of factors, and identifying these root causes is the critical first step in any legal claim. A thorough investigation by a skilled truck accident lawyer is essential because evidence can be complex, technical, and perishable. An experienced lawyer acts swiftly to preserve critical data from the truck's "black box" (ELD/ECU), driver logs, dispatch records, and witness accounts. By uncovering all contributing factors—from a momentary driver error to systemic company-wide negligence or a latent equipment failure—a lawyer ensures that all responsible parties are held accountable, which is crucial for maximizing the potential for fair compensation. Understanding these potential causes is the first step toward building a strong legal case focused on truck accident causes and liability.

Cause 1: Driver Error and Negligence

The actions of the truck driver are often a primary focus when a truck accident lawyer investigates the causes of a crash. Driver negligence can take many forms, including:

• Driver Fatigue: A leading cause of accidents. The Federal Motor Carrier Safety Administration (FMCSA) has strict Hours-of-Service (HOS) rules to prevent drowsy driving. A lawyer will subpoena driver logs and electronic logging device (ELD) data to check for violations.
• Speeding and Aggressive Driving: To meet unrealistic deadlines, drivers may exceed speed limits, tailgate, or make unsafe lane changes. The truck's black box data, GPS records, and witness testimony are key evidence here.
• Distracted Driving: Using cell phones, GPS systems, dispatching devices, or even eating while driving can be catastrophic. Phone records and in-cab camera footage (if available) can prove this form of negligence.
• Driving Under the Influence (DUI/DWI): Impairment from alcohol, illegal drugs, or even certain prescription or over-the-counter medications is a serious violation. A truck accident lawyer will obtain police toxicology reports.
• Lack of Training or Experience: A driver may lack the specific skills to handle an oversized load, hazardous materials, or adverse weather conditions like high winds or icy roads. A lawyer will scrutinize driver qualification files and training records.

Cause 2: Trucking Company Negligence

Often, the fault extends beyond the driver to the trucking company (motor carrier) that employs them. A truck accident lawyer will investigate systemic corporate issues to establish liability, such as:

• Negligent Hiring and Retention: Employing drivers with a history of safety violations, DUIs, or insufficient qualifications.
• Inadequate Training or Supervision: Failing to properly train drivers on company safety procedures, the specific equipment they operate, or FMCSA compliance.
• Pressuring Drivers: Using dispatch schedules, pay-per-mile incentives, or direct coercion to encourage drivers to violate HOS rules or speed.
• Failure to Maintain Vehicles: Neglecting a systematic program of vehicle inspection, repair, and preventative maintenance as required by federal law.
• Lack of a Safety Culture: Not implementing or enforcing adequate safety policies, leading to a culture that prioritizes speed and profits over public safety.

Cause 3: Vehicle Equipment Failure and Maintenance Issues

A catastrophic mechanical failure can be a primary factor in truck accident causes and liability. A truck accident lawyer will demand and analyze maintenance records to look for issues such as:

• Brake Failure: This is a common problem, often due to worn-out brake pads, improperly adjusted brakes, or air line defects.
• Tire Blowouts or Tread Separation: Resulting from excessive wear, underinflation, or defective retreads.
• Steering or Suspension Failure: Worn-out components can lead to a sudden loss of control.
• Defective Lights and Reflectors: Poorly maintained lights or missing conspicuity tape can make a truck nearly invisible at night, leading to devastating underride accidents.
• Coupling Failures: A defective fifth wheel can cause a trailer to detach from the tractor, creating a runaway trailer on the highway.

Liability for equipment failure can rest with the trucking company for negligent maintenance, a third-party repair shop for shoddy work, or the manufacturer of a defective part.

Cause 4: Improper Cargo Loading

The way cargo is loaded and secured is critical to a truck's stability. If cargo is overloaded, unbalanced, or improperly secured, it can shift during transit, causing the driver to lose control or the truck to roll over. The party responsible for loading and securing the cargo—which could be the trucking company or a separate third-party shipper—may be held liable. A truck accident lawyer will investigate bills of lading, weight tickets, and loading diagrams to determine if cargo-related negligence contributed to the crash.
