The impact sent the big rig over the center divider, four people in the car were hospitalized, and both directions of I-5 were closed. Below, San Diego truck accident lawyers Pajman and Parisima Jassim explain what happened, why truck crashes differ from car crashes, and what injured drivers should do next.  Learn more from a trusted San Diego truck accident lawyer.

What Happened in the Mission Hills I-5 Truck Crash?

According to ABC 10News, the California Highway Patrol received the report at about 9:44 a.m. CHP confirmed the collision caused the semitruck to cross the center divider. Fire officials said four people in the car were taken to a hospital with various injuries, while two people in the truck were evaluated at the scene and did not need hospital care. A Sig Alert closed northbound and southbound I-5 near Washington Street. The cause has not been released, and the CHP investigation is ongoing.

Why Are Truck Accidents More Dangerous Than Car Accidents?

A loaded tractor-trailer can weigh up to 80,000 pounds, about 20 times more than a typical car. When a truck crosses a median, oncoming drivers have almost no time to react. Truck cases are also legally more complex:

  • Multiple liable parties. The driver, trucking company, cargo loader, maintenance contractor, or parts manufacturer may share fault.
  • Federal safety rules. Commercial carriers must follow Federal Motor Carrier Safety Administration (FMCSA) rules on driver hours, rest breaks, inspections, and maintenance.
  • Larger insurance policies. Interstate carriers carry far more coverage than private drivers, and their insurers often begin building a defense within hours.
  • Road and barrier design. When a heavy truck crosses a median, the barrier may be examined. Claims against a government entity generally must be filed within six months.

What Evidence Matters Most After a Semi-Truck Accident?

The most important evidence in a truck case is usually controlled by the trucking company, and some of it can be lost within weeks:

  • Electronic logging device (ELD) data showing driver hours
  • Engine control module (“black box”) data on speed and braking
  • Dash-cam and in-cab video
  • Driver qualification, training, and drug-testing files
  • Brake, tire, and steering maintenance records
  • Caltrans and traffic camera footage

A written preservation demand, and when necessary an early lawsuit with subpoena power, keeps that evidence from disappearing.

How Does Jassim Law Handle Truck Accident Cases?

Trucking companies often deny fault and point elsewhere. In one of our cases, a semi tractor-trailer swerved into oncoming traffic and the defense blamed a “phantom” vehicle that left the scene. We investigated what the trucking company would not, and the case resolved for $9,000,000.

Jassim Law is a selective San Diego personal injury trial firm. For more than two decades, our approach has been the same. Your case is handled directly by attorneys Pajman Jassim and Parisima Jassim, not a case manager. We file suit early, retain accident reconstruction experts, and prepare every truck case for trial from day one.

What Should You Do After a Truck Accident in San Diego?

  1. Get medical care immediately, even if injuries seem minor.
  2. Get the CHP collision report number.
  3. Photograph the scene and record the truck’s USDOT number and company name.
  4. Do not give a recorded statement to the trucking company’s insurer.
  5. Speak with a truck accident lawyer before evidence is lost.

Frequently Asked Questions

Liability depends on the cause. The truck driver, the trucking company, a maintenance provider, or another motorist may share fault. In some cases, the design of the median barrier is also examined.

The general deadline to file a personal injury lawsuit in California is two years from the date of injury. Claims against a government entity, such as Caltrans, generally must be presented within six months.

For serious injuries, yes. Truck cases involve federal regulations, multiple defendants, and large commercial insurers that act quickly. An experienced truck accident lawyer can preserve evidence and hold every responsible party accountable.
