A major injury crash involving a semi-truck and multiple passenger vehicles shut down State Route 132 in both directions near Vernalis on Tuesday afternoon, leaving several people with significant injuries and raising serious questions about roadway safety on one of the Central Valley’s busiest rural corridors. For the victims and families affected by this crash, understanding their legal rights and options is an important first step toward recovery.

What Happened on Highway 132 in Vernalis
According to the California Highway Patrol, the collision occurred at approximately 4:00 p.m. on Tuesday, July 8th, on Highway 132 just west of State Route 33 in the unincorporated community of Vernalis.
Initial reports indicate that a white Honda Civic collided with three other vehicles and a semi-truck in a multi-vehicle crash. While the driver of the Honda Civic reportedly walked away without injuries, other individuals involved in the collision suffered significant injuries requiring emergency medical treatment.
Stockton Fire Department units and CHP officers responded to the scene to manage the aftermath of the crash. All injured parties were transported to a regional medical facility for treatment. The extent of their injuries had not been disclosed as of this writing. The collision forced a temporary closure of SR-132 in both directions while emergency crews worked to clear the scene and coordinate tow services to remove the damaged vehicles from the roadway.
Highway 132 through Stanislaus County, particularly the stretch near its junction with State Route 33, is patrolled by the CHP Modesto Area office and is known among local officers as one of the more hazardous two-lane corridors in the region, carrying a steady mix of commuter traffic, agricultural equipment, and heavy commercial trucking.
Multi-Vehicle Crashes and Semi-Truck Liability in California
When a collision involves a commercial semi-truck and several passenger vehicles, determining fault can be far more complicated than in a standard two-car accident. Investigators must examine driver logs, vehicle maintenance records, cargo loading, and the trucking company’s compliance with federal and state safety regulations, in addition to the usual factors like speed, following distance, and roadway conditions.
Under Civil Code §1714, every person in California owes a duty to exercise reasonable care to avoid injuring others, and that duty extends to commercial drivers and the companies that employ them. If a semi-truck driver was fatigued, distracted, improperly trained, or driving a vehicle with mechanical defects, both the driver and the trucking company may bear liability.
Because California follows pure comparative fault, more than one party can be held responsible, and compensation is allocated according to each party’s percentage of fault. This matters greatly in a crash involving four vehicles and a truck, where responsibility may be shared among several drivers.
How Settlement Value Is Calculated in Multi-Vehicle Collision Claims
Victims of serious multi-vehicle crashes often face a complicated web of medical bills, lost income, and long-term rehabilitation needs. Attorneys typically rely on one of two methods to calculate a fair settlement value for pain and suffering damages.
The multiplier method multiplies the total of a victim’s economic damages, including medical expenses and lost wages, by a number typically ranging from 1.5 to 5, depending on the severity of the injury and its impact on the victim’s life. A catastrophic injury involving surgery, long-term disability, or permanent impairment will generally justify a higher multiplier than a soft-tissue injury with a full recovery.
The per diem method instead assigns a specific dollar value to each day the victim experiences pain, discomfort, or diminished quality of life, then multiplies that daily rate by the number of days the victim is expected to endure those effects. This method is often used for injuries with a defined recovery period, such as a broken bone that heals over several months.
Because multi-vehicle crashes frequently involve overlapping insurance policies from several drivers and a commercial trucking company, calculating a full and fair settlement requires a careful review of all available coverage, not just the policy of the driver who appears most at fault.
Catastrophic Injury Settlement Calculators and How They Help Determine Fair Compensation
Catastrophic injuries, such as traumatic brain injuries, spinal cord damage, amputations, and severe burns, permanently alter a victim’s life, and the financial recovery needed to address these losses must reflect that reality. A catastrophic injury settlement calculator provides attorneys, insurance adjusters, and victims with a structured starting point for estimating the full value of a claim, accounting for both economic and non-economic damages.
On the economic side, the calculator factors in past and future medical expenses, including surgeries, hospitalizations, rehabilitation, in-home care, and medical equipment, along with lost wages and diminished future earning capacity if the victim can no longer work in the same capacity, or at all.
For non-economic damages, which cover pain, suffering, loss of enjoyment of life, and emotional distress, attorneys typically apply the multiplier method, taking the total economic damages and multiplying that figure by a number often ranging from 3 to 5 for catastrophic injuries, reflecting the severity and permanence of the harm.
In some cases, the per diem method is used instead, assigning a daily dollar value to the victim’s pain and suffering and multiplying it by the number of days the effects are expected to last, which may extend across the victim’s entire life expectancy in the most severe cases. Because catastrophic injuries often require lifelong care.
Also, a thorough settlement calculation must account for future costs, including ongoing physical therapy, assistive devices, home modifications, and long-term nursing support. While no calculator can capture every nuance of a person’s suffering or the full weight of a life forever changed, it provides a critical framework for building a case that reflects the true cost of the injury, and for pushing back against insurance companies that routinely undervalue these claims.
