Common Causes of Truck Accidents—And How to Prove Them in California

How Razavi Law Group Can Help You Seek Justice After a Truck Crash

Truck accidents are among the most devastating collisions on California roadways. With massive vehicles traveling at high speeds, even a minor error can result in catastrophic consequences for other motorists. If you’ve been injured in a truck crash, understanding the common causes and knowing how to prove liability is key to securing compensation.

In this post, we’ll break down the most frequent causes of truck accidents in California, explain what evidence is used to support claims, and how Razavi Law Group can help you through every step of the legal process.

 Common Causes of Truck Accidents in California

1. Driver Fatigue

   • Despite federal Hours of Service (HOS) rules, truckers may drive beyond safe limits to meet deadlines.

   • Why it’s dangerous: Fatigue slows reaction times and impairs decision-making, often causing rear-end or lane drift crashes.

2. Distracted Driving

   • Texting, using a GPS, or even eating behind the wheel can divert a trucker’s attention from the road.

   • Evidence: Phone records, dashcam footage, and witness statements help demonstrate distraction.

3. Speeding or Reckless Driving

   • Some truck drivers speed to meet tight delivery windows. Others may tailgate or change lanes aggressively.

   • Impact: Speed reduces stopping distance, especially for 18-wheelers traveling downhill on highways like I-5 or CA-99.

4. Improperly Loaded or Secured Cargo

   • Shifting loads can cause rollovers or jackknife accidents, especially on curves or during sudden stops.

   • Liability: The trucking company or cargo loader may be responsible if they violated FMCSA cargo securement rules.

5. Mechanical Failures or Poor Maintenance

   • Worn brakes, tire blowouts, and steering system failures often stem from neglect.

   • Records to review: Maintenance logs, inspection reports, and black box data.

6. Driving Under the Influence

   • Although rare, impaired truck driving can lead to devastating multi-vehicle collisions.

   • Proof: Police reports, toxicology tests, and arrest records.

7. Inexperienced or Unqualified Drivers

   • Some companies cut corners and hire undertrained drivers who may lack CDL certification or safe driving skills.

   • Employer liability: Hiring practices, training protocols, and background checks come under scrutiny.

How to Prove the Cause of a Truck Accident in California

California is an at-fault state, which means you must prove that the truck driver or company was negligent. Here’s how Razavi Law Group builds a strong case:

• Black Box Data
  The truck’s Electronic Logging Device (ELD) and Event Data Recorder (EDR) can show speed, braking patterns, and driving hours.

• Driver Logs and Company Records
  These reveal potential violations of Hours of Service laws or lack of routine vehicle maintenance.

• Surveillance and Dashcam Footage
  Cameras at intersections, business fronts, or within the truck itself can show what really happened.

• Expert Accident Reconstruction
  We work with accident reconstructionists who use physics, skid marks, and vehicle damage to determine cause and fault.

• Witness Statements and Police Reports
  First-hand accounts and official documentation often form the foundation of a liability claim.
