You were sitting in traffic on the 405 somewhere between the Victory Blvd and Sherman Way exits, or maybe near the Burbank Blvd on-ramp, and the car behind you didn't stop. The impact came out of nowhere. Your head snapped back, your car lurched forward, and now you're on the shoulder with your hazards on, trying to figure out what just happened and what comes next.

Here's what comes next. Step by step.

Step 1: Get Safe and Call 911

If your car is drivable, pull to the right shoulder or the nearest exit. The 405 through Van Nuys carries enormous traffic volume and the shoulder is narrow in sections. Staying in an active lane after a crash is dangerous. Turn on your hazard lights, get out of the car if it's safe, and stand behind the guardrail if there is one.

Call 911. On the 405, CHP responds to collisions, not LAPD. Tell the dispatcher your direction of travel, the nearest exit or overpass you can see, and whether anyone is injured. CHP will dispatch an officer and, if needed, paramedics. Do not skip this step. The CHP collision report is the single most important document in your case.

Step 2: Document Everything at the Scene

While waiting for CHP, use your phone. Photograph the rear of your vehicle showing the impact damage. Photograph the front of the other car. Get both license plates. Photograph the road surface, any debris, skid marks, and your position on the freeway relative to exits and overpasses. Capture the traffic conditions, because stop-and-go traffic on the 405 through Van Nuys is the context that explains why this happened.

Exchange information with the other driver: name, phone number, insurance company, policy number, driver's license number. If other drivers stopped as witnesses, get their names and numbers now. Freeway witnesses don't stick around.

Step 3: Get Medical Attention the Same Day

This part is not optional, even if you feel okay right now. Rear-end crashes produce a specific injury pattern: whiplash, neck strain, upper and lower back injuries, and concussions. These injuries are caused by the sudden deceleration force that snaps your head and neck backward and then forward. The adrenaline from the crash masks the pain for hours, sometimes days.

Go to Valley Presbyterian Hospital on Vanowen St in Van Nuys the same day. Their emergency department sees a high volume of motor vehicle crash patients. If your injuries aren't emergent but you're still in pain, an urgent care visit the same day creates the medical record you need. That same-day record ties your injuries directly to the crash date. A gap of even a few days between the crash and your first medical visit gives the insurance adjuster ammunition to argue your injuries came from something else.

Why Rear-End Crashes Are Strong Cases

Here's something most people don't know: rear-end collisions are the strongest liability cases in California car accident law. There is a legal presumption that the following driver is at fault in a rear-end crash. The reasoning is simple. A driver has a duty to maintain a safe following distance and keep their vehicle under control. If they hit you from behind, they failed that duty.

This presumption doesn't mean the at-fault driver's insurer won't fight you. They will. Common defenses include arguing that you stopped suddenly without cause, that your brake lights were out, or that you cut into their lane and braked. These defenses are usually weak, especially in stop-and-go traffic on the 405 where everyone is braking constantly. But you need evidence to counter them, which is why the CHP report, your photos, and witness information matter.

One common issue in 405 rear-end crashes: the at-fault driver will claim traffic stopped suddenly. On the 405 through Van Nuys, traffic stops suddenly all the time. That's not a defense. Every driver on that freeway knows traffic is unpredictable, and maintaining a safe following distance is their responsibility regardless.

What Evidence to Preserve

The 405 corridor through Van Nuys has traffic monitoring cameras operated by Caltrans and LA Metro. Not all of them record continuously, but some capture footage that can show traffic conditions at the time of your crash. Your attorney can submit a request to Caltrans to preserve any available footage from the relevant cameras and time frame.

Dash cam footage from your own vehicle or the at-fault driver's vehicle is increasingly common and extremely valuable. If you have a dash cam, save the footage immediately. If the other driver had one, note the make and model of their vehicle and inform your attorney, who can subpoena the footage.

Keep all documentation from Valley Presbyterian Hospital, CHP, and any follow-up medical providers organized and accessible. Your medical records, the collision report, and photographic evidence form the core of your claim.

The Insurance Process After a 405 Rear-End

Report the crash to your own insurance company the same day. Provide the CHP report number and the other driver's information. Do not give a recorded statement to the other driver's insurer. They will call, probably within 24 to 48 hours. Be polite, give them your name and the CHP report number, and tell them you're not prepared to discuss the details or provide a statement.

The other driver's insurer will likely accept liability relatively quickly in a clear rear-end case. But accepting liability and offering fair compensation are two different things. They'll try to settle fast, before you know the full extent of your injuries. Do not accept an early offer without understanding your complete medical situation.

A Van Nuys car accident attorney who handles 405 rear-end cases can evaluate the offer against what your claim is actually worth and negotiate accordingly. Rear-end crash cases involving documented whiplash, physical therapy, and missed work routinely settle for significantly more than the insurer's first offer.

What You Can Recover

In a rear-end crash on the 405, compensation typically includes:

• Medical expenses: ER visit at Valley Presbyterian, imaging, specialist referrals, physical therapy, pain management, and future treatment.
• Lost wages: Income lost during recovery, plus reduced earning capacity if injuries are lasting.
• Pain and suffering: Physical pain, emotional distress, and disruption to your daily life.
• Vehicle damage: Repair or replacement of your car, plus a rental vehicle during repairs.

Rear-end crash cases in LA County regularly settle between $30,000 and $200,000 depending on injury severity and treatment duration. Cases involving surgery or permanent injury can go higher.

Don't Wait to Act

The CHP report, the camera footage, the witness recollections, and the medical connection between the crash and your injuries all degrade with time. The sooner you document everything and talk to an attorney, the stronger your case will be.
