If you were rear-ended on the I-8 in El Cajon, call 911, get medical attention, and contact an attorney before speaking to any insurance company. And make sure you do that all within the first 24 hours. In California, the driver who rear-ends you is almost always at fault under California Vehicle Code Section 21703, but the steps you take right now determine how strong your claim will be.
The I-8 through El Cajon is one of the most congested and unpredictable stretches of freeway in San Diego County, and right now, while you are still figuring out how you feel, the other driver’s insurance company has already started building their case.
Attorney Daniel Petrov knows this playbook inside out, and this guide will walk you through exactly what to do before they get the upper hand.
Why the I-8 in El Cajon Is a High-Risk Corridor
The I-8 through El Cajon is one of the most congested stretches of freeway in San Diego County. Heavy commuter traffic, frequent lane merges, and the interchange with SR-67 create conditions where rear-end collisions happen regularly, particularly during morning and evening rush hours and in the stop-and-go traffic near the El Cajon Boulevard and Mollison Avenue exits.
If you were hit on this stretch of road, you are far from alone. And the steps you take in the first 24 hours will shape everything that follows.
Step-by-Step: What to Do in the First 24 Hours
1. Stay at the Scene and Call 911
Do not move your vehicle unless it is creating a safety hazard. Call 911 immediately. A police report is one of the most important pieces of evidence in a rear-end accident claim as it documents the scene, records the other driver’s information, and creates an official record of what happened before memories fade and evidence disappears.
2. Check for Injuries and Do Not Refuse Medical Attention
Many rear-end accident victims feel fine at the scene and only begin experiencing pain hours or days later. Whiplash, herniated discs, and traumatic brain injuries are among the most common rear-end collision injuries, and all of them can have delayed onset.
If paramedics offer to evaluate you at the scene, accept their help. If you decline and symptoms appear later, the insurance company will use that gap against you.
3. Document Everything at the Scene
While you are waiting for police to arrive, if you are physically able:
- Photograph the damage to both vehicles from multiple angles
- Photograph the road conditions, skid marks, and traffic signals
- Capture the other driver’s license plate, insurance card, and driver’s license
- Get the names and contact information of any witnesses
- Note the exact location, time, and direction of travel
On a busy freeway like the I-8, traffic camera footage may also be available. Your attorney can move quickly to request this footage before it is overwritten.
4. Do Not Admit Fault or Apologize
Even a casual “I’m sorry” at the scene can be used against you later. California follows a pure comparative negligence standard, which means any statement that suggests you contributed to the accident could reduce your compensation. Say as little as possible beyond exchanging information and cooperating with law enforcement.
5. Seek Medical Attention Within 24 Hours
Even if you feel relatively okay after the accident, see a doctor before the end of the day. Tell your doctor exactly what happened and describe every symptom, however minor it seems. This visit creates a medical record that directly links your injuries to the accident, which is something insurance companies will look for ways to challenge if there is any gap in care.
6. Notify Your Insurance Company
Report the accident to your insurer as soon as possible. Most policies require prompt notification. However, do not give a recorded statement, do not describe your injuries in detail, and do not accept any settlement offer before speaking with an attorney.
7. Contact a Car Accident Attorney
The single most important call you can make in the first 24 hours is to an attorney. Insurance adjusters begin building their case the moment a claim is filed. Having legal representation from the start means someone is preserving evidence, handling communications with the insurer, and making sure you do not say or sign anything that reduces your claim.

Who Is at Fault in a Rear-End Accident in California?
California Vehicle Code requires all drivers to maintain a safe following distance. A driver who rear-ends you has almost certainly violated this statute. That said, insurance companies will still attempt to assign partial fault to you, claiming you braked suddenly, had a broken brake light, or cut off the other driver.
Under California’s pure comparative negligence standard, your total compensation is reduced by your percentage of fault, but you are not barred from recovering anything. So do not accept any fault determination from an insurer without speaking to an attorney first.

Frequently Asked Questions About Rear-End Accident on the I-8 in El Cajon
1. What should I do immediately after being rear-ended on the I-8?
Call 911, stay at the scene, document everything you can, and seek medical attention within 24 hours even if you feel okay. Do not give a recorded statement to any insurance company before speaking with an attorney. Evidence on a busy freeway like the I-8 disappears quickly, including camera footage, witness accounts, and physical evidence; all need to be preserved fast. Contact Petrov Personal Injury Lawyers for a free consultation now.
2. Can I still recover compensation if I was partly at fault for the rear-end accident?
Yes. California follows a pure comparative negligence standard, meaning your compensation is reduced by your percentage of fault, but you are not barred from recovering anything. Insurance companies frequently try to assign partial fault to the front driver, so having an attorney push back on that determination makes a significant difference. If the driver who hit you was uninsured, find out who pays for your injuries and what your options are.
3. Who is at fault in a rear-end accident in California?
In almost all cases, the driver who hits you from behind is at fault. California Vehicle Code Section 21703 requires drivers to maintain a safe following distance at all times. A driver who fails to do so and rear-ends your vehicle has violated this statute, which is strong evidence of negligence.
4. What injuries should I watch for after a rear-end accident?
Whiplash, herniated discs, and traumatic brain injuries are the most common rear-end collision injuries, and all of them can have delayed onset. If you experience neck or back pain, headaches, dizziness, numbness, or difficulty concentrating in the hours or days after your accident, see a doctor immediately and tell them about the collision.
5. How long do I have to file a rear-end accident claim in California?
You generally have two years from the date of the accident under California Code of Civil Procedure Section 335.1. If a government vehicle or poorly maintained road contributed to the accident, the deadline may be as short as six months.
6. Why should I contact a lawyer before talking to the insurance company?
Insurance adjusters are trained to minimize payouts. Anything you say in a recorded statement can be used to reduce your claim, including casual descriptions of your injuries or how the accident happened. An attorney handles all communications with the insurer on your behalf and makes sure you do not say or sign anything that affects your recovery. Daniel Petrov offers free consultations with no fees unless you win.
