Quick Answer
Commercial truck accidents in California result from a combination of driver errors, FMCSA regulatory violations, vehicle maintenance failures, and cargo mismanagement. Understanding why truck accidents happen is critical for two reasons: it identifies all potentially liable parties (not just the driver), and it establishes the strongest legal theories for maximum recovery. Attorney Damoun Yazdi investigates all contributing causes — using ELD data, EDR black box data, maintenance records, and FMCSA compliance files — immediately upon retention.

I can't explain in this short review how much Damoun and his team mean to us, but I'll try. My husband was in a near fatal motor cycle accident. He was T-boned by a pick up truck 4 months after we had our baby girl. The stress, fear and sadness I felt could not be measured I had no idea what to do or what happened. I'm so lucky we connected with Damoun and his group. It was a weekend and of course he was working lol. They really took care of us and put our minds at ease. The care and love they give their clients is unreal and I still can't believe how lucky we were to find them. Please if you need help, want someone who cares and will work for you this is the group. Damoun Yazdi you are amazing and so is your group we love you guys. Thank you for changing our lives for the better and for caring.
Key Takeaways
- Driver fatigue from FMCSA hours of service (HOS) violations (49 CFR Part 395) is the leading cause of serious commercial truck accidents
- Distracted driving (cell phone use in violation of 49 CFR 392.82), speeding, and following too closely are major controllable driver factors
- Mechanical failures caused by inadequate maintenance (brake failure, tire blowout) are trucking company failures that extend liability beyond the driver
- Improperly loaded or overweight cargo that causes loss of control or cargo spillage creates shipper and carrier liability
- FMCSA drug and alcohol testing violations (49 CFR Part 382) that allowed an impaired driver to operate the vehicle support punitive damages under California Civil Code Section 3294
Driver Fatigue and Hours of Service Violations
FMCSA Hours of Service regulations (49 CFR Part 395) limit how long commercial truck drivers can drive without rest. The property-carrying rules limit drivers to 11 hours of driving within a 14-hour on-duty window, with a 10-hour off-duty rest period required between shifts. Carriers who pressure drivers to falsify ELD logs or exceed HOS limits — and drivers who comply — are liable for accidents caused by the resulting fatigue.
Driver fatigue is the critical reason in a significant percentage of large truck crashes. Fatigued driving impairs reaction time, judgment, and attention comparably to alcohol impairment. Attorney Yazdi obtains ELD data and carrier dispatch records immediately to detect HOS violations.
Mechanical Failures and Inadequate Maintenance
Federal Motor Carrier Safety Regulations (49 CFR Part 396) require carriers to systematically inspect, repair, and maintain all commercial motor vehicles. Brake failures, tire blowouts, steering failures, and lighting failures that cause accidents are the carrier’s liability when caused by inadequate maintenance. Post-accident inspection of the truck’s physical condition and pre-trip inspection logs establishes whether maintenance failures contributed.
Other Leading Causes
Distracted driving: 49 CFR Section 392.82 prohibits commercial drivers from using handheld cell phones while driving. A trucking company that fails to enforce this prohibition faces direct liability.
Overloaded/unsecured cargo: Federal bridge weight laws and cargo securement regulations (49 CFR Part 393) prohibit overweight loads and require cargo to be properly secured. A shifted load that causes loss of control or a dropped load that strikes other vehicles creates shipper and carrier liability.
Speeding: CVC Section 22350 and federal speed regulations require speed appropriate for conditions. A truck exceeding safe speeds on a grade, curve, or in adverse conditions is liable under negligence per se.
