Car Accidents, Traumatic Brain Injuries, and Your Right to Full Compensation in California

Why TBI Claims After Car Accidents Demand Serious Legal Attention

I’m Michael Hackard, founder of Hackard Law. Over five decades of practice, I have fought for people who were hurt through no fault of their own  –  people whose lives changed in an instant because someone else was careless behind the wheel. I have written four books on protecting the rights of injury victims and heirs, and our firm has produced more than 1,000 educational videos that have reached over seven million viewers. We serve clients throughout California, including Sacramento, the San Francisco Bay Area, and Los Angeles.

Car accidents are one of the leading causes of traumatic brain injury in this country. When a crash changes your life, you deserve a legal team that understands what that injury actually costs  –  not just in medical bills, but in every dimension of your daily existence.

Hackard Law takes qualified injury cases on a contingency fee basis, meaning you pay nothing upfront. If we do not recover for you, you owe us nothing. To speak with our team, call (916) 313-3030.

Quick Summary

Car accidents cause roughly one in four traumatic brain injuries, and many victims do not connect their symptoms to the crash. California law allows injured people to pursue full compensation for both economic and non-economic losses.

• Car accidents account for approximately 25% of all TBI cases nationwide.
• Up to 90% of TBI patients experience vision-related problems, according to leading eye care professionals.
• Symptoms are often subtle and easily missed  –  or misattributed to stress or aging.
• A thorough legal and medical record is essential to building a strong compensation claim.
• Contingency fee representation means qualified victims can pursue justice without upfront legal costs.

The Hidden Scale of Brain Injuries in Car Crashes

Most people think of a brain injury as something obvious  –  a skull fracture, a loss of consciousness, a dramatic scene. The reality is far more complicated. A significant number of TBIs result from the rapid acceleration and deceleration forces in a car crash, even when there is no direct blow to the head. The brain moves inside the skull, and that movement causes damage that may not show up on a standard scan.

Car accidents are responsible for about one in four traumatic brain injuries in the United States. That statistic alone should change how insurers, courts, and families think about crash injuries. When someone walks away from a collision and says they feel fine, that assessment may be incomplete  –  and dangerously so.

For a deeper look at why so many survivors miss the signs, see why some brain injury survivors don’t realize they’re injured.

Vision Problems: The Overlooked Symptom

Some of the most respected professionals in eye care report that roughly 90% of TBI patients experience some form of vision disruption. That is not a minor footnote  –  it is a central feature of how brain injuries manifest.

Vision problems after a TBI can include blurry or double vision, sensitivity to light, eye strain, and unusual fatigue when reading or using a screen. People may find themselves avoiding crowded spaces, bumping into objects, or struggling to track moving items. These are not personality quirks or signs of anxiety. They are neurological symptoms tied directly to the injury.

The challenge is that many people  –  and many doctors  –  do not connect these symptoms to a car accident that happened weeks or months earlier. That gap in recognition can cost victims dearly when it comes time to document their losses.

Case Pattern: A driver rear-ended at moderate speed reported persistent headaches and difficulty working at a computer. For months, the symptoms were attributed to stress. A neuro-optometric evaluation later identified convergence insufficiency and other post-TBI vision deficits. Proper documentation of that diagnosis became central to the damages case.

Why Victims Don’t Recognize Their Own Injuries

One of the most frustrating realities in TBI litigation is that the injury itself can impair a person’s ability to recognize how impaired they are. This is not denial or exaggeration  –  it is a documented neurological phenomenon. The same damage that disrupts memory, attention, and processing speed can also reduce a person’s awareness of those deficits.

This creates a practical problem. Victims may delay seeking care, minimize their symptoms to family members, or fail to report the full scope of their limitations to a treating physician. By the time they consult an attorney, the early medical record may be thin  –  and insurance adjusters will use that gap against them.

Tools like the Brain Injury Visual Symptom Survey can help quantify the severity of visual and cognitive symptoms in a structured, documented format. That kind of objective measurement matters when building a credible claim. To understand what California courts and insurers look at when evaluating these cases, see what the average TBI settlement looks like in California.

Case Pattern: A passenger in a rideshare collision reported feeling mostly fine after the crash. Weeks later, she noticed she could no longer tolerate grocery stores or busy intersections. A neuropsychological evaluation confirmed significant processing speed deficits. The documented functional limitations  –  not just the initial injury report  –  drove the ultimate recovery in her case.

Building a Credible TBI Claim

Insurance companies are businesses. Their financial interest runs in the opposite direction from yours. When a TBI is involved, they will look for every reason to minimize the injury, question the connection to the crash, or argue that symptoms existed before the accident.

The answer to that pressure is a well-constructed record. That means prompt medical evaluation, consistent treatment, and documentation that ties every limitation  –  visual, cognitive, emotional, physical  –  back to the accident. It also means working with credible medical professionals whose opinions can withstand scrutiny in settlement negotiations or at trial.

Michael Hackard has spent decades understanding that credibility is not just a courtroom virtue. It shapes every stage of a case, from the first demand letter to the final resolution. The story of what happened  –  and what it cost  –  must be told clearly, completely, and honestly. If you are wondering whether you have grounds to pursue a claim, this resource on suing for brain damage is a useful starting point.

Documenting Every Loss  –  Economic and Beyond

A TBI settlement should reflect the full reality of what the injury took from you. That includes medical expenses, lost wages, and reduced earning capacity. It also includes what the law calls non-economic damages  –  pain and suffering, loss of enjoyment of life, the inability to participate in activities that once defined your days.

For many TBI survivors, the non-economic losses are the most significant. The person who could no longer coach their child’s team, maintain a career they had built for years, or simply sit in a restaurant without sensory overload  –  those losses are real, and they are compensable under California law.

Documenting non-economic losses requires more than a list of complaints. It requires a consistent narrative supported by medical records, witness accounts, employment records, and sometimes vocational or life-care planning assessments. Every piece of that record strengthens the claim.

Key Definitions

• Traumatic brain injury (TBI): A disruption in normal brain function caused by a bump, blow, or jolt to the head, or by a penetrating injury  –  including injuries from the rapid deceleration forces in a car crash.
• Post-concussion syndrome: A condition in which TBI symptoms persist for weeks or months beyond the initial injury, often including headaches, cognitive difficulties, and mood changes.
• Neuro-optometric rehabilitation: A focused area of eye care focused on diagnosing and treating vision problems that arise from neurological injury, including TBI.
• Brain Injury Visual Symptom Survey (BIVSS): A standardized questionnaire used to assess the type and severity of visual symptoms experienced by TBI patients.
• Non-economic damages: Compensation for losses that do not have a direct dollar value, such as pain and suffering, emotional distress, and loss of enjoyment of life.
• Economic damages: Quantifiable financial losses including medical bills, lost wages, future care costs, and reduced earning capacity.
• Contingency fee: A legal fee arrangement in which the attorney is paid only if the case is successfully resolved  –  no upfront cost to the client.
• Anosognosia: A neurological condition in which a person is unaware of their own cognitive or physical deficits, common in TBI patients.
• Convergence insufficiency: A vision condition frequently seen after TBI in which the eyes struggle to work together when focusing on close objects.

What to Do Next

• Get a medical evaluation as soon as possible after any car accident, even if you feel relatively fine.
• Look for vision-related symptoms in the weeks following a crash  –  blurriness, light sensitivity, difficulty with screens, or trouble in busy environments.
• Try to avoid waiting too long to document symptoms; early records are critical to a strong claim.
• Get copies of all accident reports, medical records, and correspondence with insurance companies.
• Consider a neuro-optometric evaluation if you are experiencing any visual or perceptual difficulties.
• Look for an attorney who handles TBI cases on a contingency basis so cost is not a barrier to representation.
• Keep a daily log of how your symptoms affect your work, relationships, and daily activities.
