A 90-year-old San Diego man has died after suffering a medical emergency while driving north on Interstate 5, stopping his Ford pickup truck in a travel lane before another vehicle struck it. The crash happened Monday just north of Palm Avenue, and while the collision itself caused no injuries, the man was taken to a local hospital, where he was later pronounced dead.
According to the FOX 5 San Diego and KUSI News report, the man appeared to suffer a medical event and stopped in the number two lane of the highway, where a Toyota pickup truck driven by a 25-year-old woman crashed into his vehicle. The California Highway Patrol said the secondary collision resulted in no injuries, but the man's underlying medical crisis proved fatal. His name has been withheld pending family notification, the outlet reports.
The California Highway Patrol is investigating the cause and sequence of events, while the San Diego County Medical Examiner's Office will determine whether alcohol or drugs were a factor, per the same report. CHP is asking anyone who witnessed the crash to come forward and call its office at (858) 293-6000.
Why I-5 and Highway Patrol, Not Local Police
Interstate 5 falls under state jurisdiction rather than municipal authority, meaning crash scene investigation and traffic enforcement responsibility on the freeway belongs to the California Highway Patrol rather than the San Diego Police Department, according to the County of San Diego. The stretch of I-5 near Palm Avenue functions as a key regional artery, linking the Otay Mesa border region, Imperial Beach, and South Bay communities to downtown San Diego, per SANDAG.
Hoodline has also reported a separate medical-emergency crash: a Sunrise home SUV crash involving another elderly driver.
How California Law Treats Medical-Emergency Crashes
Cases like this one sit at the intersection of medical oversight and road safety regulation. Physicians are legally required under California Health and Safety Code Section 103900 to immediately report any patient diagnosed with a condition involving lapses of consciousness or severe cognitive impairment to local health officers, who then notify the California DMV, according to the County of San Diego. After receiving a notification, the DMV may evaluate a driver's ability to drive and take appropriate action.
Civil liability in these cases also follows a distinct legal path. Under California Civil Jury Instruction CACI No. 452, the sudden emergency or imminent peril doctrine may apply when a party faces actual or apparent danger of immediate injury, did not cause the emergency, and acts reasonably, according to Advocate Magazine. A party invoking the doctrine must establish those elements. Separately, state law already requires drivers age 70 and older to renew their licenses in person every five years and pass a vision screening at a DMV office, per the California DMV.
The Crash Involved a Senior Driver
Monday's crash involved a 90-year-old driver and occurred during the day.
The investigation into Monday's crash remains open, with the medical examiner still working to determine whether substances played any role and CHP continuing to piece together exactly how the sequence of events unfolded.
