Traumatic brain injuries are among the most complex and consequential injuries that can result from a motor vehicle accident. They're also among the most difficult to navigate from a legal and insurance standpoint — especially in a large urban area like San Diego, where accidents range from freeway pile-ups on the I-5 to low-speed intersections collisions that can still produce serious head trauma.
This page explains how TBI claims generally work, what factors shape outcomes, and why brain injury cases are treated differently than other personal injury claims.
Most soft-tissue injuries — strains, sprains, bruising — resolve within weeks or months. The medical picture is relatively predictable, and insurance adjusters have experience valuing them.
TBI cases are different for several reasons:
Like other accident claims, a TBI case in San Diego generally begins with identifying who was at fault and what insurance applies. California is an at-fault state, meaning the driver responsible for the crash is generally liable for resulting injuries — including brain injuries.
Key coverage types that may apply:
| Coverage Type | What It Covers |
|---|---|
| At-fault driver's liability insurance | Medical costs, lost wages, pain and suffering up to policy limits |
| Your own UM/UIM coverage | Applies if the at-fault driver is uninsured or underinsured |
| MedPay | Pays your medical bills regardless of fault, up to policy limits |
| Health insurance | May cover treatment, but often subject to subrogation claims |
When damages exceed the at-fault driver's policy limits — which is common in serious TBI cases — underinsured motorist (UIM) coverage through your own policy becomes critically important. The gap between a $50,000 liability policy and a $500,000 medical bill is a situation TBI claimants regularly face.
California allows injured parties to seek both economic and non-economic damages in personal injury claims.
Economic damages include:
Non-economic damages include:
California does not cap non-economic damages in most motor vehicle accident cases (unlike medical malpractice). That said, the value of any individual claim depends heavily on documented severity, expert testimony, and the specific facts of the case. 🧠
California follows pure comparative negligence, meaning your compensation is reduced by your percentage of fault — but you can still recover even if you were partly responsible. If a jury found you 30% at fault for a crash that caused your TBI, your damages would be reduced by 30%.
This matters in TBI cases because insurers frequently investigate whether the injured party contributed to the accident or failed to wear a seatbelt — both of which can affect how fault is allocated.
Brain injury claims involve high stakes and significant complexity. Most TBI attorneys in San Diego — and elsewhere — work on a contingency fee basis, meaning they receive a percentage of any recovery (commonly 33–40%, depending on whether the case settles or goes to trial), and collect nothing if the case doesn't result in compensation.
What an attorney typically handles in a TBI case:
California's statute of limitations for personal injury claims is generally two years from the date of injury — but exceptions apply depending on who is at fault, whether a government entity is involved, and when the injury was discovered. These timelines are case-specific and can be shorter or longer depending on the facts.
The severity of your TBI, the coverage available, who bears fault, and what California law allows in your specific circumstances — these aren't abstract variables. They're the factors that determine what happens next and how different outcomes become possible.
General information explains the framework. What happens in a specific claim depends on details that no overview can substitute for.
