38% of crashes here are rear end collisions. That concentration often points to inadequate signal timing, poor visibility of upcoming stops, or traffic volume that exceeds what the intersection was designed to handle. For someone injured in a crash at this intersection, this pattern is relevant because it can shift liability from the individual driver to the entity responsible for the road.

Crashes at Janss Road & SR-23 peak around 5 PM on Thus. If the city has traffic studies showing the same pattern, and they have not adjusted signal timing, added turn lanes, or improved sight lines in response, that is evidence of notice.

Senior Attorneys, Not a Call Center

I grew up in Thousand Oaks, graduated from Thousand Oaks High School and UCLA Law School, and I've spent my career fighting for people who were seriously hurt in crashes across the Conejo Valley and greater Los Angeles. These cases aren't just files on a desk. I know what families go through after a serious accident, and I take that responsibility seriously.

Dangerous road design

When the Intersection Itself Is the Problem

Not every crash is a driver's fault. Under California Government Code § 835, a public entity, whether it's a city, county, or Caltrans, can be held liable when a dangerous condition on public property causes injury. A "dangerous condition" can include poor sight lines, missing turn lanes, inadequate signage, confusing lane markings, or signal timing that doesn't account for actual traffic patterns.

What makes a road design case different from a standard auto accident claim is evidence of notice. If a city knew or should have known about a hazard and failed to fix it, they're on the hook. Crash history at a specific location is one of the strongest forms of evidence that a condition was known. When the same spot produces crash after crash, it becomes very difficult for a government entity to argue they had no idea.

Frequently asked questions

Janss Road & SR-23 Crash FAQs

How dangerous is Janss Road & SR-23?
CHP data shows 13 reported crashes at Janss Road & SR-23 in the last nine months, with an injury rate of 38%.
Can I sue the city for a crash at Janss Road & SR-23?
Potentially, yes. Under California Government Code Section 835, a public entity can be held liable for injuries caused by a dangerous condition of public property. The crash pattern at Janss Road & SR-23 may constitute evidence that the city had notice of a dangerous condition. You must file a government tort claim within six months of the accident, or you lose the right to sue.
Why are there so many rear end crashes at Janss Road & SR-23?
Rear End collisions account for 38% of crashes at this intersection. This often points to inadequate signal timing, poor visibility of upcoming stops, or traffic volume that exceeds what the intersection was designed to handle. An attorney can investigate whether the road design contributed to your crash and whether the city had prior notice of the problem.
What should I do after a crash at Janss Road & SR-23?
Get medical attention immediately, even if you feel fine. Document the scene with photos if you can. Get the other driver's insurance information and contact details for any witnesses. Request a copy of the police report. Do not give a recorded statement to the other driver's insurance company before speaking to an attorney. Evidence fades quickly, and the sooner an attorney can begin preserving it, the stronger your case will be.
How long do I have to file a personal injury claim in California?
For most personal injury claims in California, you have two years from the date of the injury to file a lawsuit (California Code of Civil Procedure Section 335.1). However, if you believe the road design contributed to your crash, you must file a government tort claim within six months. Missing either deadline can permanently bar your claim.
