This page provides general information about California law and local procedures as they apply to injuries in Corte Madera. It is not legal advice, and reading it does not create an attorney-client relationship. Every case depends on its own facts. For advice about your specific situation, consult a licensed California attorney.
Corte Madera is small, but a lot of traffic passes through it: Highway 101, the Tamalpais Drive interchange, two shopping centers, and some of the busiest bicycle routes in Marin. That mix shows up in the collision data. Compared with the rest of the county, a much larger share of the serious crashes in Corte Madera involve someone on a bike or on foot.
I’m Sami Sedghani, a personal injury lawyer. My office is in downtown San Rafael on 4th Street, a few miles north on Highway 101. This page covers what is specific to injury claims in Corte Madera: which agency writes the report, what the County’s safety data says about local streets, and where a claim against the Town goes. For the general California rules, see our car accident page.
Two agencies, and the CHP office is in town
Corte Madera does not have its own police department. Town streets are patrolled by the Central Marin Police Authority, a joint agency formed in 2013 by Corte Madera, Larkspur, and San Anselmo. A crash on Tamalpais Drive, Paradise Drive, or another town street is generally a Central Marin Police Authority report.
Highway 101 is different. Crashes on the freeway and its ramps are handled by the California Highway Patrol, and the CHP’s Marin Area office happens to sit in Corte Madera, at 53 San Clemente Drive. That office covers freeway crashes and crashes in unincorporated areas throughout Marin County, not just Corte Madera.
Getting the report
- Central Marin Police Authority: reports are requested from the Records Office at the Larkspur station, 250 Doherty Drive, Larkspur, in person or by mail, fax, or email. The department’s public records page lists a $10 fee for reports, payable by cash or check, and contact within 10 business days of a written request.
- CHP Marin Area: reports are requested through the CHP crash report request process, online, by mail, or in person at the San Clemente Drive office.
- Who can get it: collision reports are released only to people with a proper interest under Vehicle Code § 20012, such as the drivers and injured people involved, a parent of an involved minor, their attorneys, and their insurers.
What the County’s data says about Corte Madera streets
The 2024 Marin County Local Road Safety Plan, prepared for the Transportation Authority of Marin and the County, has a chapter on Corte Madera. It counts 74 injury collisions on the Town’s arterial and collector streets from 2017 through 2021. Eight caused severe injuries, and none were fatal. Unsafe speed was the primary factor in 30 percent of them, compared with 26 percent countywide. Freeway crashes are not included in those numbers.
The figure that sets Corte Madera apart is who gets hurt. From 2012 through 2021, bicyclists were involved in about 20 percent of the Town’s injury collisions and 42 percent of its fatal and severe-injury collisions. Countywide, the same figures were 9 percent and 17 percent. Pedestrians were involved in 33 percent of Corte Madera’s fatal and severe-injury collisions.
The plan identifies these locations:
- Tamalpais Drive, Willow Avenue to the Highway 101 ramp. 22 injury collisions from 2017 through 2021, about 60 percent of them involving a pedestrian or bicyclist. Collisions in dark conditions clustered on Tamalpais Drive between Willow Avenue and Lakeside Drive.
- Tamal Vista Boulevard and Fifer Avenue, Wornum Drive to Lucky Drive. Part of the Town’s High Collision Network.
- Park Madera Shopping Center on Tamalpais Drive. A hotspot for bicycle collisions and for improper-turning collisions.
- Corte Madera Avenue. A bicycle collision hotspot. Its intersection with Redwood Avenue is one of three Town intersections in the plan’s High Collision Network, along with Tamalpais Drive and Willow Avenue and Tamal Vista Boulevard and Fifer Avenue, although the plan notes their collision rates are low by countywide standards.

When you are hit on a bike in Corte Madera
Bicycle crash claims turn on a few rules that come up again and again on Corte Madera’s streets:
- Passing distance. A driver passing a bicyclist in the same direction must leave at least three feet, under Vehicle Code § 21760, and must slow down or wait when three feet is not possible. Since 2023, a driver passing a bicyclist in the same lane must also change lanes when another lane is available and it is practical to do so.
- Opening a car door. No one may open a vehicle door into traffic unless it is reasonably safe to do so, under Vehicle Code § 22517. Shopping center parking and curbside parking near the Town’s commercial blocks make door collisions a real risk.
- Turning across a bike. Right-hook and left-turn crashes, where a driver turns across a bicyclist’s path, are the improper-turning pattern the plan flagged at Park Madera Center. The turning driver’s duty to yield is usually the central question.
- The driver has little or no insurance. Your own uninsured and underinsured motorist coverage on your auto policy can apply even though you were on a bicycle, not in your car. Check your declarations page before assuming there is no coverage.
California uses comparative fault, so a rider who was partly at fault can still recover, reduced by his or her share of responsibility. Expect the driver’s insurer to look closely at lights, lane position, and speed. Bike computer data, a helmet camera, or a ride-tracking app can answer those questions, so save the file before the device syncs or overwrites it.
Road projects, flooding, and claims against public agencies
Several Corte Madera projects affect how crashes happen and who may share responsibility:
- The Town’s Paradise Drive Complete Street Project covers about 1,700 feet from Westward Drive to the town limit. It adds a multi-use path and an enhanced crosswalk between Marin Montessori and Marin Country Day School, and it raises part of the roadway against flooding. The Town lists construction for spring 2027.
- Caltrans plans repair and seismic work on the Highway 101 overcrossing at Tamalpais Drive. The Town’s project page says the structure is at risk of seismic failure because it cannot be fully inspected, and construction has been postponed to about 2028.
- In early January 2026, king tides, storm surge, and runoff caused extensive tidal flooding in low-lying parts of Corte Madera.
- The Central Marin Regional Pathway Gap Closure at the Highway 101 interchange (Wornum Drive, Nellen Avenue, and Fifer Avenue) was completed in October 2024.
When a roadway condition contributes to a crash, the claim depends on who owns the road. A Town street goes to the Town. A state highway, including the 101 interchange and overcrossing, goes to the State through the Department of General Services. Either way, a government claim for personal injury is generally due within six months (Government Code § 911.2), and the claimant must usually show a dangerous condition that the agency created, or knew or should have known about in time to fix (Government Code § 835). Flooding and construction are not automatic proof of either. They are reasons to find out who controlled that stretch of road and what the agency knew.
Flooded roads and weather: what public agencies are and are not responsible for
Low-lying Corte Madera streets flood during king tides and storms. Under Government Code § 831, a public entity is not liable for the effect of weather conditions as such, including fog, rain, and flood, on the use of streets. The same section does not protect the agency when the effect would not be reasonably apparent to, or anticipated by, a person using due care, and it does not cover physical damage to or deterioration of the street itself.
In practice, a driver who hydroplanes through obvious standing water usually has a claim only against another driver, if anyone. A hidden washout, a pothole created by flooding, or a closure that was not signed can be different. Photographs of the water line, barricades, and signs at the scene are often the deciding evidence.
Bicycle rules that come up in Corte Madera claims
- Lane position. Vehicle Code § 21202 generally requires a bicyclist moving slower than traffic to ride as close as practicable to the right edge, with exceptions for passing, turning left, avoiding hazards such as fixed or moving objects, vehicles, pedestrians, and surface hazards, and lanes too narrow to share. Insurers raise this rule often; the exceptions frequently apply on Tamalpais Drive and Paradise Drive.
- Helmets. California requires helmets for riders under 18 (Vehicle Code § 21212), not for adults. An adult rider’s choice not to wear a helmet is sometimes argued as comparative fault for a head injury, but it does not excuse the driver who caused the crash.
- Group rides. Paradise Drive is a popular route for group and recreational riding. When a crash involves several riders, each rider’s position and speed, and any ride-tracking data, can matter as much as the driver’s account.
Paths and crossings around the Highway 101 interchange
The Town describes the active transportation routes connected by its Central Marin Regional Pathway Gap Closure project as carrying more than 1.6 million trips a year. That project, completed in October 2024, closed gaps at Wornum Drive, Nellen Avenue, and Fifer Avenue near the interchange. A crash on a path, at a path crossing, or where a path meets a street can involve the Town, Caltrans, or another agency depending on exactly where it happened, so the precise location is one of the first facts to pin down.
Filing a claim against the Town of Corte Madera
Claims against the Town are made on the Town’s claim form and sent to the Town Clerk at Corte Madera Town Hall, 300 Tamalpais Drive, Corte Madera, CA 94925, according to the Town’s claims page. Sanitary District No. 2 has its own claim process. A lawsuit, if one follows, is generally filed in the Marin County Superior Court, 3501 Civic Center Drive, San Rafael.
E-bikes and riders under 16
Corte Madera’s ordinance limiting Class 2 (throttle) e-bikes to riders 16 and older took effect July 1, 2025, according to the County of Marin’s youth e-bike safety page. If a young rider is hurt, the two-year lawsuit deadline is generally paused until age 18 under Code of Civil Procedure § 352, but a claim against the Town, Caltrans, or a school district still runs on the six-month government claim clock, subject to a possible late-claim application.

How we prepare a bicycle or pedestrian injury case
Riders and pedestrians tend to suffer the injuries that insurers dispute most: fractures that heal but leave lasting limitation, shoulder and knee injuries with arguably pre-existing wear, and concussions that never show on a scan. I am a former clinical pharmacist, and I read those medical records asking the questions the defense expert would ask, looking at medication history, gaps in care, and whether the notes tie the crash to the diagnosis.
Before founding Synergist Law, I spent nine years at large law firms handling complex and product liability litigation on behalf of companies, so I know how the other side builds its evaluation. Neither background predicts any outcome. It shapes how I prepare a case.

Frequently asked questions about Corte Madera injury claims
Who handles a car accident in Corte Madera?
On town streets, the Central Marin Police Authority, which serves Corte Madera, Larkspur, and San Anselmo. On Highway 101 and its ramps, the California Highway Patrol’s Marin Area office, which is located at 53 San Clemente Drive in Corte Madera.
How do I get a Central Marin Police Authority accident report?
Requests go to the Records Office at the Larkspur station, 250 Doherty Drive, in person or by mail, fax, or email. The department lists a $10 report fee, payable by cash or check, and contacts the requester within 10 business days. Reports are released only to people with a proper interest under Vehicle Code section 20012.
Are bicycle crashes common in Corte Madera?
Compared with the rest of Marin, yes. The 2024 Marin County Local Road Safety Plan found bicyclists were involved in 42 percent of Corte Madera’s fatal and severe-injury collisions from 2012 through 2021, versus 17 percent countywide. Tamalpais Drive between Willow Avenue and the Highway 101 ramp had 22 injury collisions from 2017 through 2021, about 60 percent involving a pedestrian or bicyclist.
Does my car insurance cover me if I was hit while riding a bike?
Often, yes. Uninsured and underinsured motorist coverage on your own auto policy can apply when you are injured by an uninsured or underinsured driver while on a bicycle. Policy terms vary, so the declarations page and policy language control.
Is the CHP office in Corte Madera only for Corte Madera crashes?
No. The California Highway Patrol Marin Area office at 53 San Clemente Drive covers freeway crashes and crashes in unincorporated areas throughout Marin County. Crashes on Corte Madera town streets are handled by the Central Marin Police Authority instead.
Can I sue the Town if I crashed on a flooded Corte Madera street?
Usually not for the weather itself. Government Code section 831 protects public entities from liability for the effect of weather conditions such as rain and flood on the use of streets, but not when the danger would not be reasonably apparent to a careful person, and not for physical damage to the road. A claim against the Town is generally due within six months. Because the deadline depends on the facts, it is better to have a licensed California attorney determine the deadline that applies than to calculate it yourself.
Do adult cyclists in California have to wear a helmet?
No. Vehicle Code section 21212 requires helmets for riders under 18. An insurer may argue that an adult’s lack of a helmet contributed to a head injury, but that argument goes to comparative fault and does not excuse the driver who caused the crash.
