What to Do After a Car Accident in California: A Medical Checklist
The minutes after a crash are confusing, and the most important health decisions often come days later. This checklist walks you through the scene, the first 72 hours, the paperwork, and when to get examined.

In our Oceanside and Carlsbad offices, I often meet people a week or two after a crash who tell me the same thing: they felt shaken but fine, so they went home, and only later did the neck stiffness, headaches, or low back pain show up. By then they are hurting, unsure what to do, and worried they waited too long.
This checklist is meant to prevent that. It covers what to do at the scene, what to watch for over the next few days, which symptoms need the emergency room, the paperwork California expects from you, and how care is usually paid for. It is general information, not legal advice, so talk with an attorney about the legal side of your case.

Quick answer
After a car accident in California, check for injuries and call 911 if anyone is hurt, move to a safe spot, exchange information, and photograph the scene. Get a medical exam within a few days even if you feel fine, because whiplash symptoms are often delayed. File an SR-1 report with the DMV within 10 days if anyone was injured.
Key takeaways
- Call 911 for any injury, and go to the ER first for red flag symptoms such as confusion, numbness, or weakness.
- Feeling fine at the scene does not rule out a neck or back injury, so plan an exam within a few days.
- California requires an SR-1 report to the DMV within 10 days when anyone is injured or damage tops $1,000.
- A simple symptom log with dates protects both your health and any later claim.
- MedPay and third party claims on lien let most accident patients start care without paying up front.
At the scene: the first 30 minutes
Your health comes before the car, the paperwork, or the other driver. If you can move safely, work through these steps in order.

- Check yourself and your passengers for injuries. If anyone is hurt, call 911 right away and do not move someone with neck or back pain unless they are in danger.
- Turn on your hazard lights and move to the shoulder or a safe spot if the cars can be driven. California law requires drivers involved in a crash to stop.
- Exchange names, phone numbers, driver license numbers, insurance companies, and policy numbers with the other driver.
- Photograph both vehicles, license plates, the road, traffic signals, skid marks, and any visible injuries.
- Get names and phone numbers of witnesses before they leave.
- Write down how you feel right now, even if the answer is "a little sore" or "fine." That first note becomes the start of your symptom log.
The first 72 hours: watch for delayed symptoms
Adrenaline can hide pain for hours. As inflammation builds in strained muscles and ligaments, stiffness and soreness often peak one to three days after the crash. Our guide to whiplash explains why this delay is so common.
The National Library of Medicine's StatPearls review of cervical sprain notes that most people with whiplash recover within days to weeks, but symptoms that last beyond three months are less likely to resolve fully. That is one reason an early exam and an early plan matter.
| When | What to do | Why it matters |
|---|---|---|
| Day of the crash | Note every ache, rest if needed, keep moving gently | Creates a dated starting point for your symptoms |
| Days 1 to 3 | Watch for neck stiffness, headaches, back pain, arm tingling | This is when delayed symptoms most often appear |
| Within the first week | Get a hands on exam even if pain seems mild | Finds problems early and documents them |
| Weeks 2 to 6 | Follow your care plan and report any change | Most soft tissue injuries improve steadily in this window |
| After 3 months | Ask for a reassessment if you still hurt | Lingering symptoms need a more structured plan |
Symptoms that mean go to the ER first
A chiropractor is a good first stop for most muscle and joint injuries after a crash. Some symptoms are different and need emergency care before anything else.
Call 911 or go to the emergency room if you have
Loss of consciousness, confusion, a headache that keeps getting worse, repeated vomiting, trouble speaking, numbness or weakness in the arms or legs, trouble walking, loss of bladder or bowel control, chest or belly pain, or severe neck pain after a high speed crash. Once you are cleared, we can help with soft tissue injury care.
Why you should get checked even if you feel fine
Many crash injuries are soft tissue strains of the neck and upper back, and they do not show up on the day of the accident. Others start as a mild ache and grow into headaches at the base of the skull, neck pain that limits checking your blind spot, or lower back pain that makes sitting hard.
An exam within a few days does two things. It finds problems that respond best to early care, and it records your symptoms close to the date of the crash. Insurance adjusters often question a gap of several weeks between an accident and a first visit, so earlier is better for your health and your claim.
Keep moving in the meantime. Short walks and normal daily activity usually help more than staying in bed, while heavy lifting or hard workouts in the first week can aggravate injured tissue.
Paperwork that protects your health and your claim
The DMV's own SR-1 form instructions spell out the 10 day deadline, and the California Department of Insurance auto insurance guide explains coverage types, including MedPay.
- File an SR-1 Report of Traffic Accident with the DMV within 10 days if anyone was injured or killed, or property damage was over $1,000. This is your responsibility even if police came to the scene.
- Tell your own auto insurer about the crash promptly and ask whether your policy includes medical payments coverage (MedPay).
- Keep a symptom log with dates: what hurts, how much, and what makes it better or worse.
- Save every bill, receipt, mileage note, and appointment record in one folder.
- Do not sign a release or accept a settlement from the other driver's insurer before you know the full extent of your injuries.
How care is usually paid for after a California crash
MedPay is optional coverage on your own auto policy that can pay for medical care for you and your passengers no matter who caused the crash, up to your policy limit. If another driver was at fault, your care may also be paid from their insurance through a personal injury claim, often on a lien so you do not pay up front.
Pacific Spine & Rehab accepts MedPay and third party personal injury claims on lien. We do not participate with most health plans, including TRICARE. Our auto accident care page walks through the process, and our personal injury page explains how we work with attorneys and adjusters. You can also review our insurance and payment options.
What your first visit looks like with us
Your first visit starts with a detailed history of the crash and every symptom since, followed by range of motion, orthopedic, and neurological testing. If the findings suggest a fracture, disc injury, or nerve involvement, we refer you for imaging or to a medical specialist. When care is appropriate, plans usually combine gentle chiropractic care, soft tissue work, and rehab therapy that rebuilds strength so the injury is less likely to linger. Every visit is documented for your attorney or adjuster.
Our Oceanside auto accident office on Vista Way and our Carlsbad office in Bressi Ranch offer same day visits most weekdays. Hours are Monday to Friday 10 AM to 6 PM and Saturday 10 AM to 4 PM, with free parking and Spanish spoken.
Frequently asked questions
What should I do immediately after a car accident in California?
Check for injuries and call 911 if anyone is hurt, move to safety if you can, exchange driver and insurance information, photograph the scene, and get witness contacts. Then plan a medical exam within a few days.
Do I have to report a car accident to the DMV in California?
Yes, if anyone was injured or killed or property damage was over $1,000. You must file an SR-1 with the DMV within 10 days, even if police made a report.
How soon should I see a doctor after a car accident?
Go to the ER right away for red flag symptoms. Otherwise, an exam within a few days is a good goal, because whiplash symptoms are often delayed and early records help your claim.
Can I see a chiropractor after a car accident?
Yes. A chiropractor can evaluate and treat most muscle and joint injuries after a crash and will refer you for imaging or medical care if anything more serious is suspected.
Will I have to pay out of pocket for accident care?
Usually not. We accept MedPay and third party personal injury claims on lien, so qualifying accident patients can start care without paying up front.
