California’s Most Dangerous Highways

Fatal car crashes saw a big jump during the COVID-19 pandemic. And while the numbers may have peaked, they’re still well above pre-pandemic levels.

“It’s a crisis that needs to be reversed,” Timothy Weisberg, deputy director of marketing and public affairs at the California Office of Traffic Safety, told Consumer Affairs. “During the pandemic, we saw more of those dangerous driving behaviors.”

Consumer Affairs just released rankings of the top 10 deadliest freeways in California based on the number of fatalities in 2022 versus 2018. Southern California appears especially dangerous. The top four dangerous highways are in SoCal.

The rankings are as follows:

  1. San Bernardino County: I-15
  2. Riverside County: I-10
  3. San Diego County: I-5
  4. Orange County: I-5
  5. Santa Barbara County: US-101
  6. Alameda County: I-880
  7. Contra Costa County: SR-4
  8. Los Angeles County: I-10
  9. Kern County: SR-178 / SR-99 (Tie)
  10. Santa Clara County: US-101

There were 48 fatal crashes on the I-15 in San Bernardino County in 2022. Four years earlier, there were 33. The I-10 in Riverside had 31 fatal crashes in 2022 compared to 25 in 2018.
