You're shaking. Your heart's racing. You just got hit, and your mind is spinning with a thousand questions. What do I do? Who do I call? Am I okay?
Here's the truth: what you do in the next few minutes can make or break your injury claim. We've seen it happen hundreds of times. Good people make simple mistakes right after a crash: and those mistakes cost them thousands of dollars in compensation they deserve.
We're Fairmont Law Firm. Since 2012, we've fought for California accident victims across all 58 counties. We've secured hundreds of millions in settlements and verdicts. And we've seen every mistake in the book.
Today, we're breaking down the seven biggest errors people make after a car accident in California: and exactly how to fix them before it's too late.
Mistake #1: You Leave the Scene Too Early
The Problem: You think the accident is minor. Maybe just a fender bender. You exchange a quick "sorry" with the other driver and head home. No big deal, right?
Wrong. Leaving before you've fulfilled your legal obligations can turn you into a hit-and-run suspect. California Vehicle Code § 20001 is crystal clear: if your accident causes any injury, death, or property damage, you must stop and remain at the scene.
Leaving early doesn't just put you at legal risk. It also destroys your injury claim. Insurance companies will argue you weren't really hurt. They'll say if you were injured, you would've stayed.
How to Fix It:
☑ Stop your vehicle immediately in a safe location
☑ Check yourself and others for injuries
☑ Call 911 if anyone is hurt or if there's significant damage
☑ Stay at the scene until police arrive and complete their report
☑ Exchange information with all parties involved
☑ Wait for law enforcement to tell you it's okay to leave
Don't let fear or confusion turn a fixable situation into a criminal charge. Stay put. Protect yourself.

Mistake #2: You Don't Call the Police
The Problem: The other driver seems nice. They apologize profusely. They promise their insurance will handle everything. You shake hands and go your separate ways without calling the cops.
This is a massive mistake. Without an official police report, you have no neutral documentation of what happened. It becomes your word against theirs. And guess what? When it's time to file a claim, that "nice" driver suddenly has a completely different story.
California law requires you to report any accident involving injury, death, or property damage over $1,000. You must file a written report with police or the California Highway Patrol within 24 hours if there's an injury. For property damage crashes, you have 10 days to file with the DMV.
Skip this step, and the DMV can suspend your license. Insurance companies can deny your claim. You lose credibility and leverage.
How to Fix It:
☑ Call 911 or the non-emergency police line immediately after the accident
☑ Request an official police report, even if the crash seems minor
☑ Get the report number and the officer's name and badge number
☑ File the required DMV SR-1 form within 10 days for property damage cases
☑ Keep copies of all documentation for your records
A police report is your foundation. It establishes the facts before anyone has time to change their story.
Mistake #3: You Delay Getting Medical Treatment
The Problem: You feel okay. A little sore, maybe, but nothing serious. You tell yourself you'll see a doctor "if it gets worse." Days turn into weeks. Then the pain hits hard: and suddenly you're facing a destroyed injury claim.
Insurance companies are ruthless about medical gaps. They'll argue that if you were really injured, you would've gone to the hospital immediately. They'll claim your injuries came from something else. They'll use your delay as a weapon to pay you nothing.
Many serious injuries don't show symptoms right away. Whiplash. Concussions. Internal bleeding. Soft tissue damage. These injuries can take hours or even days to manifest.
How to Fix It:
Step 1: Get checked out at the scene by paramedics if they're available.
Step 2: Go to the emergency room or an urgent care clinic within 24 hours: even if you feel fine.
Step 3: Tell the doctor about every symptom, no matter how minor it seems.
Step 4: Follow all treatment recommendations and attend every appointment.
Step 5: Keep detailed records of all medical visits, bills, and prescriptions.
Early medical documentation creates an unbreakable link between the accident and your injuries. It proves causation. It shows the insurance company you're serious: and you deserve full compensation.

Mistake #4: You Apologize or Admit Fault
The Problem: You're a good person. The accident just happened. Your instinct is to say "I'm sorry" or "I didn't see you." It feels natural. It feels polite.
But those words can destroy your case. In California, any statement that sounds like an admission of fault can be used against you. The insurance company will twist "I'm sorry" into "I accept full responsibility." They'll reduce or deny your claim based on your own words.
California operates under pure comparative negligence law. That means your compensation gets reduced by your percentage of fault. If you're found 30% at fault, you lose 30% of your settlement. Every word you say at the scene can shift that percentage against you.
How to Fix It:
☑ Do not apologize, even if you feel bad
☑ Do not speculate about what happened or who's at fault
☑ Stick to the facts when speaking to police: "The light was green" or "I was stopped when they hit me"
☑ Exchange information politely but don't discuss the accident details
☑ Let investigators and lawyers determine liability based on evidence
☑ If the other driver tries to get you to admit fault, simply say: "I need to speak with my attorney"
Your compassion is admirable. But save it for after your case is resolved. At the scene, silence protects you.
Mistake #5: You Fail to Document the Scene
The Problem: You're rattled. You just want to get out of there. You exchange insurance cards and leave. Later, when you try to remember what happened, the details are fuzzy. Where was the stop sign? What color was the traffic light? Who had the right of way?
Without documentation, you're fighting blind. Photos and witness statements are evidence. They lock in the truth before memories fade and stories change.
Insurance adjusters will use any gap in evidence against you. They'll claim you're exaggerating. They'll argue their driver's version of events. Without proof, you lose.
How to Fix It:
Step 1: If you're physically able, use your phone to photograph everything:
- All vehicle damage from multiple angles
- The position of the vehicles on the road
- Skid marks, debris, and broken glass
- Traffic signs, signals, and road conditions
- Your visible injuries
- License plates of all vehicles involved
Step 2: Look for witnesses. Get their names, phone numbers, and brief statements about what they saw.
Step 3: Make voice notes on your phone describing the accident while it's fresh in your mind.
Step 4: Request a copy of the police report as soon as it's available.
Step 5: Don't move the vehicles until you've documented everything: unless they're blocking traffic and creating a safety hazard.
Evidence wins cases. The more you collect, the stronger your claim.

Mistake #6: You Don't Exchange Complete Information
The Problem: You're stressed. You grab the other driver's insurance card, snap a quick photo, and assume that's enough. Later, you realize you're missing their driver's license number. Or you forgot to get the VIN. Or you didn't write down their actual name: just a first name.
Incomplete information makes filing a claim nearly impossible. Insurance companies will use it as an excuse to delay or deny payment. You'll waste weeks tracking down details that should've taken 60 seconds to collect.
California Vehicle Code § 16025 spells it out: you're required to exchange specific information with all drivers involved in the accident.
How to Fix It:
Collect the following from every driver:
☑ Full legal name
☑ Current address
☑ Driver's license number and state
☑ Vehicle identification number (VIN)
☑ License plate number
☑ Insurance company name
☑ Insurance policy number
☑ Phone number
Also note:
☑ Make, model, color, and year of all vehicles
☑ Location of the accident (street names and intersection)
☑ Time and date of the collision
☑ Weather and road conditions
Take photos of insurance cards and driver's licenses. Don't rely on memory. Get everything in writing.
Mistake #7: You Settle Before Knowing Your Claim's Full Value
The Problem: You're in pain. Medical bills are piling up. You can't work. Then the insurance company calls with an offer. It sounds like a lot of money. You're desperate. You accept.
Two months later, your injuries are worse than you thought. You need surgery. You're facing permanent disability. But you already signed the release. You gave up your right to any future compensation.
Once you settle, it's over. You can't go back for more money, even if your condition deteriorates. Insurance companies know this. They lowball you early, hoping you'll take the bait before you understand the full extent of your damages.
How to Fix It:
Option 1: Wait until you reach maximum medical improvement (MMI) before settling. This means your condition has stabilized, and doctors know the full extent of your injuries.
Option 2: Consult with an experienced California car accident lawyer before accepting any offer. We review settlements for free and tell you if you're being shortchanged.
Option 3: Consider all compensable damages, including:
- Past and future medical expenses
- Lost wages and diminished earning capacity
- Pain and suffering
- Emotional distress
- Loss of enjoyment of life
- Property damage
Don't let the insurance company pressure you into a quick settlement. They work for their bottom line, not your recovery.
