Every local driver has a mental list of intersections they approach a little more carefully — the one where someone always runs the yellow, the one where the merge never quite works the way it’s supposed to. After 45 years handling serious cases across Orange County, I have come to trust those instincts. They usually match the data.
Statewide crash analysis built from California Highway Patrol collision records, covering 2020 through August 2024, ranks Newport Boulevard at 22nd Street/Victoria Street in Costa Mesa as the most dangerous intersection in all of California. Thirty-three crashes in five years, seven of them severe, are not unusual numbers for a busy intersection. What stands out is the cause: Newport Boulevard doubles as SR-55, and the intersection sits right where the surface street decides whether to become a freeway. Drivers have a split second to merge onto SR-55 North or get out of the way of someone who is, and that decision point produces a steady stream of collisions.
Not far behind in the same statewide ranking is Edinger Avenue and Ward Street in Fountain Valley — ninth overall, but first in a category no one wants to lead: it recorded more fatalities than any other intersection on the list, nearly all involving pedestrians. If you walk or bike through that intersection regularly, that’s worth knowing.
Beach Boulevard, California’s State Route 39, contributes its own cluster of hot spots: Beach and Edinger in Huntington Beach, Beach and Westminster in Westminster, Beach and Lincoln in Anaheim. Six lanes, high speed limits, and dense retail frontage are a difficult combination — drivers moving fast through a corridor full of people trying to cross on foot. T-bone collisions and pedestrian strikes are the predictable result.
Harbor Boulevard tells a similar story as it runs through Santa Ana, Costa Mesa, and Fullerton, with Harbor and Adams, Harbor and 17th Street, and Harbor and Chapman showing up again and again in collision data.
For freeway crashes, the interchange where the 405 meets the 5 in Lake Forest remains one of the busiest, most accident-prone junctions in Southern California: rush-hour stop-and-go traffic is practically a guarantee of rear-end and sideswipe collisions.
I want drivers to understand that location matters in these cases, sometimes more than people realize. A crash at a known high-collision intersection can raise questions that go beyond the two drivers involved: whether the signal timing was adequate, whether the city or Caltrans had notice of a dangerous condition, whether a left-turn pocket or sightline had already been flagged in prior complaints. Those questions can open up claims against a public entity that come with short deadlines and procedural traps — all the more reason to gather documentation (photos of the intersection, the signal phase, skid marks, witness contact information) while it’s still there to collect.
