Jackknife truck accidents, though not the most frequent incidents involving commercial vehicles, are among the deadliest in San Diego. These accidents occur when a semi-truck folds onto itself, leading to almost inevitable collisions and severe injuries for those in passenger vehicles. Victims of such accidents must seek legal counsel to investigate and establish liability, whether it lies with the truck driver, trucking company, or both. Trucking companies, under federal law, are required to carry substantial liability coverage, particularly if they transport hazardous materials, providing a potential avenue for victims to secure compensation.

Key causes of these accidents include speeding, faulty brakes, driver fatigue, and load imbalance. Speeding can cause a truck to jackknife if sudden braking is required, while defective brakes may lead to mechanical failure beyond the driver's control. Furthermore, fatigued drivers, who are overworked and tired, contribute significantly to these crashes, often in violation of federal Hours of Service regulations. Load imbalances, which can cause sudden shifts in weight, also lead to loss of vehicle control. Determining responsibility is crucial, as trucking companies and related parties may be liable for inadequate training, vehicle maintenance, or improper loading, necessitating thorough investigations by adept attorneys.
