LA Drivers: The First 72 Hours After a Car Accident Matter More Than You Think

Los Angeles personal injury attorneys see a recurring pattern after car accidents: drivers feel fine at the scene, skip a medical evaluation, and then run into trouble with their insurance claim days later when pain finally sets in.

The issue isn't just health. It's timing.

Why "Feeling Fine" Can Be Misleading

After a collision, the body releases a surge of adrenaline and endorphins that can mask pain for a day or two. Whiplash, concussions, and even herniated discs often don't produce noticeable symptoms until inflammation develops, sometimes 24 to 72 hours after the crash. A driver who walks away from an accident feeling normal isn't necessarily uninjured.

The 72-Hour Rule

There's no California law requiring accident victims to see a doctor within a specific number of hours. But insurance adjusters informally rely on what's known in the industry as the 72-hour rule when evaluating claims.

Treatment sought within the first 72 hours is rarely questioned by insurers. The picture changes as time passes:

• Four to seven days: adjusters typically view the claim with more skepticism and begin asking why treatment was delayed.
• One to two weeks: it becomes more common for insurers to argue that something other than the crash caused the injury.
• More than two weeks: claims face the steepest uphill climb, though a documented reason for the delay, such as a delayed concussion diagnosis or hospitalization, can still support a valid claim.

A Shorter Deadline for Accidents Involving Government Vehicles

Most California personal injury claims fall under a two-year statute of limitations, per California Code of Civil Procedure § 335.1. But that timeline shrinks dramatically when a government vehicle is involved, such as an LA Metro bus, a city sanitation truck, or a county-owned vehicle.

Under the California Tort Claims Act, accident victims in these cases must file a formal administrative claim within six months, not two years.

We've seen that early medical documentation and early legal consultation are especially important when a public entity may be at fault.

What This Means for LA Drivers

A delayed medical visit doesn't automatically end a claim. Many legitimate injuries take time to develop, and every case is evaluated on its own facts. But the earlier medical treatment begins, the easier it is to connect an injury to the collision when working with an insurance company.
