Common Causes of Commercial Vehicle Accidents in California — How to Prove Negligence

Commercial vehicles—delivery vans, box trucks, semi-trucks, and buses—are a common sight on California highways. When these vehicles are involved in accidents, the consequences are often severe. Identifying the root cause of a commercial vehicle accident is essential to proving negligence and securing compensation.

Leading Causes of Commercial Vehicle Accidents

• Driver fatigue: Hours-of-service violations, overworked drivers, and lack of rest.
• Distracted driving: Use of mobile devices, GPS, or eating while driving.
• Speeding and aggressive driving: Companies pushing drivers to meet tight deadlines.
• Improper vehicle maintenance: Worn brakes, tires, lights, or mechanical failures due to skipped inspections.
• Improper loading: Overloaded or unbalanced cargo can cause rollovers or loss of control.
• Lack of driver training: Inexperienced or unqualified drivers behind the wheel.
• Alcohol or drug use: Despite strict regulations, substance use can still play a role in commercial crashes.

Proving Negligence

To hold a commercial vehicle driver or their employer responsible, your attorney will need to gather and present evidence such as:

• Driver logs and electronic records
• Maintenance and inspection reports
• Onboard GPS and telematics data
• Eyewitness statements and accident reconstruction
• Company training and hiring records

In many cases, both the driver and the company may share liability for unsafe practices.

The Importance of Fast Action

Commercial carriers and their insurers act quickly to investigate and defend against claims. Victims should consult a lawyer as soon as possible to preserve evidence and begin their own investigation.
