MILL VALLEY, Marin County, Calif., Oct. 21, 2026 — Two juveniles suffered head injuries Tuesday morning, October 20, after a two-vehicle crash on the Redwood Highway Frontage Road in Mill Valley, according to the California Highway Patrol.
The crash, involving a gray Toyota Prius and a black Honda CR-V, was reported to the California Highway Patrol shortly before 6:05 a.m. near the 600 block of Redwood Highway Frontage Road. Young passengers in the Prius reportedly had head injuries and visible bleeding, the CHP log shows.
One vehicle came to rest in the roadway, and crews reportedly worked to move it into a nearby McDonald's parking lot while fire and medical units responded, per dispatch notes. The CHP classified the collision as a minor-injury crash, though the reported head injuries to the children raised concern among responding units.
Fire crews arrived on scene within roughly ten minutes of the initial call, and the CHP later confirmed all units had cleared the crash scene by mid-morning. No further details on the drivers, the cause of the collision, or the children's conditions have been released.

Frequently Asked Questions
What can drivers do to help keep young passengers safer in a crash? Making sure children are properly secured in age-appropriate car seats or seat belts remains one of the most effective ways to reduce the risk of head and neck injuries in a collision.
What are the most common injuries in two-vehicle collisions? Head injuries, cuts from broken glass, and whiplash-type neck injuries are frequently reported, especially in side-impact or intersection-style crashes.
What usually causes crashes like this one? Common factors include distracted driving, failure to yield, and misjudging another vehicle's speed or position, though the specific cause of any crash is determined only after investigators review the evidence.
Does speed make a difference in how severe a crash is? Yes. Higher speeds give drivers less time to react and increase the force involved in a collision, which often leads to more serious injuries.
What to Do After a Car Accident in Mill Valley, CA
If you're involved in a crash, check on any children or passengers first and call 911 right away, even if injuries aren't immediately obvious. Head injuries in particular can take time to show symptoms, so it's wise to have kids evaluated by a doctor as soon as possible after any collision. Try to move vehicles out of traffic only if it's safe to do so, and stay put until officers arrive to document the scene. Keep a record of what responders tell you, and follow up with your own doctor in the days after, since adrenaline can mask pain or discomfort until later.
