A crash on the I-15 or I-215 near Murrieta or Temecula can turn your day upside down in seconds. These freeways carry heavy commuter, truck and weekend traffic through the Southwest Riverside County corridor, and the stop-and-go backups near the I-15/I-215 split, Murrieta Hot Springs Road, Winchester Road and Temecula Parkway lead to many rear-end and lane-change collisions. If you were hurt, the steps you take in the first hours and days can affect your health, your insurance claim and your rights under California law.
This guide explains what to do after a car accident on the I-15 or I-215 in Murrieta and Temecula, who handles the report, which deadlines apply, and when it makes sense to talk with a Murrieta car accident lawyer. For a deeper look at the corridor itself, see our I-15 & I-215 Murrieta–Temecula accident guide.
1. Get to Safety and Call 911
If your car can move and no one is seriously hurt, California law encourages drivers to move vehicles out of traffic lanes to the shoulder or the next exit. Freeway shoulders are dangerous, so stay inside the vehicle with your seatbelt on if you cannot get safely behind a barrier. Turn on your hazard lights and call 911. Report injuries, your direction of travel and the nearest exit or mile marker (for example, “southbound I-15 just past Clinton Keith Road”).
Never leave the scene of a crash that involves injury or property damage. California Vehicle Code sections 20001 and 20002 require drivers to stop and exchange information.
2. Know Who Writes the Report
Crashes on the I-15 and I-215 freeway lanes are usually handled by the California Highway Patrol (CHP), Temecula Area office. Crashes on surface streets inside Murrieta are generally handled by the Murrieta Police Department, and Temecula city streets by Temecula Police (served through the Riverside County Sheriff). Ask the officer for the report number and the agency name before you leave. You will need it to request the collision report later.
3. Document Everything You Can
- Photos of all vehicles, license plates, damage, skid marks, debris and road conditions.
- The other driver’s name, phone, license, insurance company and policy number.
- Names and phone numbers of witnesses. Freeway witnesses often drive away quickly, so ask early.
- Notes on traffic, weather, lighting, construction zones and lane closures.
- If a commercial truck or rideshare vehicle is involved, the company name and any DOT number on the cab.
Do not argue about fault or apologize at the scene. Simple statements can be twisted later by an insurance adjuster.
4. Get Medical Care Right Away
Adrenaline hides pain. Neck, back and head injuries from rear-end crashes often show up hours or days later. Get checked at an emergency room or urgent care the same day if you can. Hospitals serving the area include Inland Valley Medical Center, Loma Linda University Medical Center–Murrieta, Rancho Springs Medical Center and Temecula Valley Hospital. Follow your doctor’s treatment plan and keep every record and bill. Gaps in treatment are one of the most common reasons insurers offer less.
5. File an SR-1 With the DMV Within 10 Days
California requires every driver involved in a crash to file an SR-1 report with the DMV within 10 days if anyone was injured or killed, or if property damage was more than $1,000. This is required even if police came to the scene and even if the crash was not your fault. Failing to file can lead to a license suspension.
6. Notify Your Insurance — Carefully
Tell your own insurer about the crash promptly, as your policy requires. Be careful with the other driver’s insurance company. Their adjuster may call quickly and ask for a recorded statement. You are not required to give one to the other side’s insurer, and it is usually wise to speak with a lawyer first. Do not sign medical releases or accept a quick check before you understand the full extent of your injuries.
If the at-fault driver has little or no insurance, your own uninsured/underinsured motorist (UM/UIM) coverage may help. California’s minimum liability limits are low compared to the cost of a serious injury, so this coverage matters.
7. Understand California Fault Rules
California follows pure comparative fault. That means you can recover damages even if you were partly at fault, but your recovery is reduced by your share of the blame. For example, if you are found 20% at fault, your damages are reduced by 20%. Insurers often try to push more blame onto injured drivers in freeway lane-change and merge crashes, which is why evidence from the scene and the CHP report is so important.
8. Watch the Deadlines
Under California Code of Civil Procedure section 335.1, the general statute of limitations for personal injury is two years from the date of the crash. Property damage claims generally have three years. If a government agency may be responsible, such as a city, county or Caltrans for a dangerous roadway condition or a public vehicle, the timeline is much shorter: under the Government Claims Act (Government Code section 911.2), a written claim usually must be filed within six months. Missing these deadlines can end your case, so do not wait.
9. Where a Murrieta or Temecula Case Is Filed
Under the Riverside County Superior Court civil filing order in effect since August 1, 2026, larger (unlimited) civil cases from Murrieta are filed at the Riverside Historic Courthouse, while smaller (limited) civil cases go to the Menifee Justice Center. Most injury claims settle without a trial, but knowing where a case would be filed helps you plan. Our Temecula personal injury page and Menifee personal injury page explain more about nearby communities.
