What happened on southbound US-101 in Larkspur
A black Toyota RAV4 and a black Infiniti sedan collided on southbound US-101 in Larkspur just north of the Sir Francis Drake Boulevard offramp. The crash happened on April 16, 2026, around 11:17 a.m., according to the California Highway Patrol.
The slow lane was blocked at first. Paramedics and other responders rushed to help at the scene.
Traffic in the Marin corridor quickly slowed to a crawl. Drivers between San Rafael and Corte Madera definitely felt the backup.
A tow crew eventually moved the badly damaged Infiniti to clear the road. Even after that, people in towns like Mill Valley and Novato kept checking CHP updates, hoping for no more delays.
Vehicle details and scene
The Infiniti took heavy front-end damage and needed a tow. The RAV4 was also involved in the crash.
Officials haven’t said much about injuries yet. It’s still not clear if anyone got hurt, as investigators are still reviewing what happened.
The California Highway Patrol wants to know exactly how the crash started. They’re asking anyone who saw it to reach out with information.
Folks in Ross, Fairfax, and San Anselmo paid close attention, along with commuters who depend on US-101 to get between Ross Valley and the Bay Area.
This whole scene really shows how important quick police reports and tow trucks are for keeping Larkspur streets and the US-101 corridor moving, especially for people heading toward Marinwood or the East Bay.
Investigation and witness information
CHP officers are digging into what led to the crash. They’re still hoping witnesses will come forward and help fill in the gaps.
The tow service cleared the damaged Infiniti, a reminder that any routine drive in Marin County can turn into a mess in seconds. There’s also a notice from a personal injury law firm, offering to get the police report and talk legal options with anyone hurt in the crash. That’s probably something to keep in mind for those involved or affected.
What this means for Marin commuters and residents
This incident really highlights how Marin County roadways—especially the busy US-101 corridor linking Larkspur, San Rafael, and Corte Madera—can change fast after a crash.
If you live or commute in the Sausalito–Marin City area, it’s smart to keep an eye on CHP updates and road conditions. Here are a few things to think about for the days ahead.
- Plan ahead for delays – Give yourself extra time if you’re heading through Larkspur, Mill Valley, or anywhere in the Marin urban triangle, especially in the morning or early afternoon. Nobody likes being late, right?
- Check traffic updates – Watch CHP advisories and Marin County transportation feeds for real-time info on lane reopenings and detours. Sometimes the official Twitter accounts are faster than the apps.
- Be mindful of responders – Slow down in work zones. Tow trucks and emergency crews need space to clear the scene and get things moving again.
- Witness tips – If you saw the crash, consider reaching out to CHP with what you know. Even small details might help improve safety in San Rafael and Larkspur.
- Know your rights – If you got hurt, talk to a local personal injury attorney. They can walk you through getting police reports or making a claim, especially if several Marin jurisdictions are involved.
Communities like Novato and South San Francisco are watching this story too. The April 16 crash is a reminder—vigilant driving and good communication with the CHP and tow operators really do matter.
