On Aug. 27, 2017, plaintiff George Diaz, 77, a retiree, was driving north on State Route 90, also known as the Marina Freeway, in Los Angeles, when it was broadsided by a vehicle operated by Maxwell Sandquist, who entered the intersection from westbound Culver Boulevard. Diaz sustained to his head. Diaz sued Sandquist, alleging that Sandquist was negligent in the operation of his vehicle. Diaz’s counsel contended that Sandquist caused the collision by failing to yield at the intersection of Culver Boulevard and SR-90, which was governed by traffic lights. Sandquist denied causing the accident, and claimed that he had the right of way when he entered the intersection., Diaz was not taken to a hospital after the collision, and he first presented for medical care three weeks after the accident. Diaz claimed he sustained a closed head injury, resulting in a concussion. He subsequently treated his condition with outpatient neurological follow-ups. In addition, Diaz, who had pre-existing anxiety, claimed that the collision aggravated his condition, causing his anxiety to worsen whenever he is driving or riding in vehicles. Diaz sought recovery of $3,000 in past medical costs for his visits with neurologists and the imaging studies he underwent. He also sought recovery of damages for his past and future physical and emotional pain and suffering. Defense counsel asserted that Diaz’s condition had resolved and that any complaints Diaz had beyond six months after the accident were not due to the crash.
