The emergency room gives you a piece of paper that says normal, and for a few hours that word does real work. Then the headaches start. The lights feel wrong. A word disappears mid-sentence in a conversation that used to be easy. The insurance adjuster calls, points to that same piece of paper, and says there is no evidence of injury.
That sequence plays out across California every year, and it is one of the most consequential mistakes an injured pedestrian can make: accepting the first scan as the final answer. A 2025 San Diego County case makes the point directly. Two pedestrians were struck in a marked La Jolla crosswalk. Both had initial scans that came back clean. Both ultimately recovered a reported $2.5 million.
That result was obtained by another firm and is cited here for illustration only. The legal lesson it demonstrates, however, applies to every pedestrian accident victim in California whose injury didn’t show up on the first round of imaging.
What Happened in the La Jolla Crosswalk
The intersection of Prospect Street and Cave Street in La Jolla is a busy pedestrian corridor. A driver making a left turn failed to yield to two people legally crossing in a marked crosswalk and struck them both. The driver later admitted fault for the collision.
Both victims went to the hospital. Both had CT scans and vascular imaging. Both came back negative. No bleeding, no fracture, nothing a radiologist could identify on the films. The defense took that finding and built its case around it: no visible injury means no real injury.
That argument collapsed. The plaintiffs documented their injuries through later clinical diagnoses, consistent treatment records, and a specialized form of neuroimaging called diffusion tensor imaging, which tracks damage to brain tissue that standard CT scans aren’t designed to detect. One of the two also required spinal surgery related to the crash. The case settled for a reported $2.5 million in San Diego County.
Why a Clean Scan Doesn’t Close a Brain Injury Claim
A CT scan is the right tool for finding emergencies: skull fractures, internal bleeding, swelling that requires immediate intervention. It isn’t designed to detect diffuse axonal injury, which is what happens when the brain’s nerve fibers stretch and tear at a microscopic level during a sudden impact. The damage is structural, it’s physical, and it doesn’t appear on a standard scan.
Diffusion tensor imaging works differently. It maps how water molecules move through the brain’s white matter pathways, which allows radiologists to identify disruptions that conventional imaging misses. In California personal injury litigation, DTI has become a recognized tool for documenting traumatic brain injuries that emergency room films didn’t capture, though its admissibility is contested in some cases and courts evaluate it alongside neuropsychological testing and a consistent clinical record, not as a standalone answer.
Insurance carriers understand exactly how CT scans work and how juries respond to clean imaging. They move quickly after a pedestrian accident, collect the ER records, lock in the negative finding, and push for a recorded statement before symptoms have fully developed. By the time a victim realizes something is genuinely wrong, the adjuster already has the file they plan to use.
The California Law That Protects Pedestrians in Crosswalks
California Vehicle Code Section 21950 is direct: a driver must yield to a pedestrian in a marked or unmarked crosswalk at an intersection. A left-turning driver who fails to yield and strikes someone legally crossing has violated that statute.
That violation matters because of a doctrine called negligence per se, codified in Evidence Code Section 669. When a driver breaks a law that exists specifically to protect pedestrians, the law presumes the driver was negligent. The presumption is rebuttable, but a driver who has already admitted fault in a crosswalk collision starts from a difficult position.
In the La Jolla case, fault was never the real fight. The defense conceded the crash. What they disputed was the injury, which is a common pattern in pedestrian TBI cases where initial imaging is negative. Winning those cases requires evidence that answers the scan.
Two Deadlines Most Pedestrian Accident Victims Don’t Know About
California gives injury victims two years from the date of the accident to file a lawsuit under Code of Civil Procedure Section 335.1. That’s the standard window for claims against a private driver.
A second, shorter deadline applies if any government entity is involved. A city-maintained crosswalk with faded paint, a poorly timed signal, or a public employee behind the wheel can each bring a government defendant into the case. When that’s possible, a formal Government Tort Claim must be filed within six months of the incident under Government Code Section 911.2. Missing it closes that claim permanently, regardless of how strong the underlying facts are.
There’s a third timing consideration that’s purely medical. In a hidden TBI case, gaps between the crash and follow-up neurological care become defense exhibits. A same-day ER visit followed by weeks of no treatment reads, to an adjuster, as evidence the injury wasn’t serious. If symptoms persist after a clean scan, a neurology appointment isn’t optional.
What an Injured Pedestrian Can Recover
California separates damages into two categories. Economic damages cover the measurable losses: emergency and hospital care, specialist visits, neuropsychological testing, physical therapy, prescription costs, lost wages, and reduced future earning capacity if the injury is permanent.
Non-economic damages address what a receipt can’t capture: pain, cognitive changes, loss of enjoyment of life, and the lasting effect on daily function and relationships. California places no cap on non-economic damages in ordinary injury cases, which is why pedestrian TBI claims with clean initial scans can still produce significant recoveries when the injury is properly documented.
The La Jolla settlement reflected both categories, against a defense that disputed the existence of the injuries from the start. The clean scan wasn’t the end of the case. It was the opening position of the defense, and the plaintiffs answered it.
Six Steps to Protect a Pedestrian Accident Claim
1. Go to the hospital the same day, even if injuries seem minor. Tell the treating physician about every symptom including headache, light sensitivity, difficulty concentrating, and ringing ears. What’s documented in the initial record becomes evidence.
2. If symptoms continue after a clean scan, see a neurologist or TBI specialist within days. The follow-up record is what connects symptoms to the crash in a way the ER films don’t.
3. Photograph the scene before leaving if possible: the crosswalk, the vehicle, the signal, and any visible injuries. Collect witness contact information. Physical details fade faster than people expect.
4. Decline any recorded statement to an insurance company before speaking with an attorney. The adjuster who calls in the first 48 hours isn’t calling to help build your case.
5. Keep a daily symptom log: headaches, sleep disruption, memory gaps, mood changes. A contemporaneous written record in the victim’s own hand is some of the most persuasive evidence a hidden injury case can produce.
6. Contact a California pedestrian accident lawyer within days. Preservation letters, the government claim deadline, and the right medical experts all depend on early action.
Frequently Asked Questions
Can a TBI claim survive a normal CT scan?
Yes. CT scans don’t detect diffuse axonal injury, which is the most common form of brain damage in pedestrian accidents. Diffusion tensor imaging, neuropsychological testing, and a consistent clinical record can document an injury that emergency room films missed. That’s exactly the type of evidence that supported the La Jolla settlement.
The driver admitted fault. Why is the insurance company still fighting the injury claim?
Because liability and damages are separate questions. Admitting the crash was their driver’s fault costs the insurer nothing if they can limit the damages by arguing the injury wasn’t serious. In hidden TBI cases, expect the dispute to shift entirely to the injury evidence once fault is off the table.
How long does a pedestrian accident victim have to file a claim in California?
Two years against a private driver under Code of Civil Procedure Section 335.1. Six months to file a Government Tort Claim if any public entity may share responsibility, under Government Code Section 911.2. If there’s any uncertainty about whether a government defendant is involved, that question needs to be answered quickly.
What if the pedestrian was partly at fault for the crosswalk accident?
Recovery is still possible. California’s pure comparative negligence rule reduces compensation by the victim’s percentage of fault but doesn’t eliminate the claim. Even a pedestrian found partly responsible can recover substantial damages from a driver who bears greater fault.
Should a pedestrian accident victim accept the insurance company’s first offer?
In a hidden TBI case, the first offer is almost always calculated from the clean scan, not from the actual injury. Future neurological care, cognitive effects, and lost earning capacity take months to fully understand. Accepting before that picture is complete closes the case permanently. The offer won’t disappear. The leverage to improve it will, the moment a release is signed.
A normal scan isn’t a verdict. It’s the defense’s opening argument, and there’s a well-established way to answer it: the right specialists, the right imaging where courts permit it, and the kind of clinical record that documents what happened to a person rather than what showed up on a film.
