Hit While Stopped on the Shoulder in California

Your car died, or you had a flat, or you pulled over after a fender bender. You got onto the shoulder, turned on your hazard lights, and a passing driver hit your car, or hit you while you were standing next to it. Now the other driver's insurer is asking why you were stopped there in the first place.

This post explains what changed in California law on January 1, 2026, how it affects who is at fault, and what the insurer is likely to argue anyway.

The move-over law now covers ordinary drivers

For years, California's "slow down, move over" rule in Vehicle Code § 21809 protected a short list of vehicles: emergency vehicles with their lights on, tow trucks, and marked highway maintenance vehicles with flashing amber lights. A regular driver stranded on the shoulder was not on the list.

AB 390, approved on July 28, 2025 and effective January 1, 2026, added everyone else. Section 21809 now also applies when a driver approaches "any other stationary vehicle displaying flashing hazard lights or another warning device, including, but not limited to, cones, flares, or retroreflective devices."

When a driver comes up on a vehicle like that, the statute requires them to approach with due caution and, before passing in the lane right next to it, do one of two things:

Move into an available lane that is not immediately adjacent to the stopped vehicle, if that is safe and practicable, or
If a lane change is not safe, slow to a reasonable and prudent speed that is safe for the weather, road, and traffic conditions.

There is one built-in exception. The duty does not apply if the stopped vehicle is not adjacent to the highway or is separated from it by a protective physical barrier.

A $50 ticket, but a much bigger civil consequence

Standing alone, a violation of § 21809 is not dramatic. It is an infraction with a fine of no more than $50.

The ticket is not what matters in an injury claim. What matters is Evidence Code § 669. Under that section, negligence is presumed when someone violates a statute, the violation causes injury, the injury is the kind of harm the statute was meant to prevent, and the injured person is in the class of people the statute was meant to protect.

Put that next to the new version of § 21809. The statute exists to keep passing traffic from hitting stopped vehicles and the people around them. If you were stopped with your hazards on and a driver sideswiped you at full speed in the next lane over, the argument that you are exactly who the law was written to protect is a strong one. Before 2026, you had to prove ordinary carelessness from scratch. Now there is a specific rule the other driver was required to follow.

A presumption is not a win. Under § 669(b), the other driver can try to rebut it by showing they acted with ordinary prudence while trying to comply, for example that there was truly no room to move over and they had already slowed. That is a factual fight, and it is won or lost on evidence.

What the insurer will say about you

Expect the adjuster to turn the question around. The usual lines are:

You should not have stopped there.
Your hazards were not on, or not visible.
You were partly in the lane.
You got out of the car when you should have stayed inside.

Some of this is a real legal question. On a full-access freeway, Vehicle Code § 21718 generally prohibits stopping, parking, or leaving a vehicle standing, but it lists exceptions. Two that come up constantly: stopping "when necessary to avoid injury or damage to persons or property," and stopping when a vehicle is "so disabled that it is impossible to avoid temporarily stopping" and help has been summoned. A breakdown or a blown tire is the situation those exceptions describe.

The rest of it is an attempt to push some of the fault onto you. That is why the details of where your car was, whether your lights were flashing, and what you were doing when you were hit matter so much. Adjusters fish for exactly these admissions early, often in a recorded statement taken before you have seen any of the evidence.

Evidence that proves you were visible

Your claim will turn on showing that the other driver had every chance to see you and move over. As soon as you are able, or have someone do it for you:

Photograph your car where it came to rest, including the hazard lights if they still work, the shoulder width, and the lane markings.
Photograph any cones, flares, or triangles you set out. The statute now expressly names these.
Get the tow and roadside records. If you called a tow company, your auto club, or the free Freeway Service Patrol (reached by dialing 5-1-1 or using a freeway call box), those records put a time stamp on when you stopped and why.
Save your phone's call log showing when you called for help.
Ask for the crash report and check whether the officer noted your hazard lights and the other driver's lane.
Identify witnesses and nearby cameras. Other stranded drivers, tow operators, and businesses along surface streets are worth asking about quickly, because footage gets overwritten.

If the driver who hit you kept going, the claim runs through a different path. Our post on hit-and-run claims in California walks through it.

If you were outside the car

A lot of these crashes happen to someone changing a tire, checking damage after a minor collision, or walking to the passenger side. Being outside the vehicle does not make you automatically at fault. It does give the insurer more to argue about, which is another reason the evidence above matters.

Fault questions here work differently from a typical rear-end collision between two moving cars, but the medical side is the same: get care right away and keep going to follow-up appointments. Gaps in treatment are one of the first things an adjuster uses to discount a claim.

What this means in California

The rule changed on January 1, 2026. Crashes before that date are judged under the older, narrower version of § 21809. Crashes after it fall under the expanded rule.
Partial fault reduces, it does not bar. California follows pure comparative negligence. If you are found partly responsible, say for where you stopped, your recovery is reduced by your share rather than wiped out.
Two years, usually. Code of Civil Procedure § 335.1 generally gives you two years from the date of injury to bring a personal injury claim.
Six months if a public entity is involved. If a government vehicle hit you, or the shoulder itself was part of the problem, a government claim is normally due within six months.

Practical next steps

Write down what happened while you still remember the details: where you stopped, why, whether your hazards were on, whether you set out anything behind the car, and when you called for help. Gather the photos, call logs, and tow records into one place, and do not give a recorded statement to the other driver's insurer until you have.
