Multi-Vehicle Crashes on California Freeways, by the Numbers
According to the National Highway Traffic Safety Administration, an estimated 2,442,581 people were injured in traffic crashes in 2023. That figure includes the kind of multi-vehicle chain collision seen on freeways like SR-110, where sudden slowdowns or lane changes can pull a third or fourth car into what starts as a two-vehicle crash.
Freeway interchanges, like the one where SR-110 meets I-5, see a concentration of these crashes because traffic merges, weaves, and changes speed within a short stretch of road. A vehicle that slows or stops to avoid one collision can be struck from behind by traffic that has less time to react.
Injury severity in these crashes varies widely depending on speed differences between vehicles and whether occupants are struck from the side or rear. Many such crashes result in lane closures that last well beyond the initial impact, as responders work to clear vehicles and assess everyone involved.
Frequently Asked Questions

A large share occur on urban roads and freeway interchanges, where merging traffic, lane changes, and speed differences increase the chance of a chain-reaction collision.
How can drivers lower their crash risk?
Keeping a safe following distance, staying alert near interchanges, and avoiding distractions can help drivers react in time when traffic ahead slows suddenly.
What injuries are common in car accidents?
Whiplash, cuts, bruises, and head or neck injuries are common, ranging from minor to serious depending on speed and the angle of impact.
What usually causes car accidents?
Distracted driving, following too closely, speeding, and sudden lane changes are among the most frequently cited factors in freeway crashes.
What to Do After a Car Accident in Elysian Park, CA
If you're involved in a crash on a busy freeway, try to move to a safe location such as a shoulder if the vehicle is drivable, and turn on hazard lights to warn oncoming traffic. Call 911 to report the crash and request medical help if anyone appears hurt, even if injuries seem minor at first.
Exchange information with the other drivers involved and, if it's safe to do so, take photos of the vehicles and the surrounding area. Seek a medical evaluation soon after the crash, since some injuries like whiplash or concussions don't show symptoms right away. Keep a copy of the CHP incident report for your records once it becomes available.
