San Francisco E-Bike Crashes Surge 28% by 2025

The SFMTA’s latest data shows a 28% jump in e-bike crashes with cars in San Francisco between 2023 and 2025. This isn’t just a number. This surge is a real problem for commuters and it brings up tough liability questions when an e-bike and a car get into it in this city’s traffic. Knowing the legal framework here is essential if you ride or drive on San Francisco’s streets.

28% Increase in E-Bike Collisions: The Reality on San Francisco Streets

That SFMTA data showing a 28% jump in e-bike collisions with cars just confirms what we see on the streets every day. This increase, which they tracked from 2023 to 2025, is a direct result of more e-bikes on the road mixed with our already gridlocked traffic. What this number signifies is a much riskier environment for anyone on an e-bike, especially in crowded areas like Market Street or the Embarcadero. When a car hits an e-bike, the rider is completely exposed and the injuries are often catastrophic. The legal side gets messy fast. Figuring out who’s at fault means we have to reconstruct the crash, looking at everything from who had the green light to whether someone made a sudden lane change without looking. This data backs up what we lawyers see in practice: e-bike accidents are more frequent and present unique challenges in proving liability to get our clients paid.

California’s Pure Comparative Negligence: Splitting the Blame

California works on a pure comparative negligence system, which is a legal doctrine that has a huge impact on how much money you can recover after getting hit by a car on your e-bike in San Francisco. It means that if you’re both partly to blame, your financial recovery gets cut by whatever percentage of fault is assigned to you. So if you have $100,000 in damages from a crash but you’re found 20% at fault (maybe you didn’t signal a turn), your recovery against the other driver is capped at $80,000. This is different from other states where you get nothing if you’re more than 50% at fault. Here in San Francisco, this rule is always in play because accidents are almost never 100% one person’s fault. A driver will say the e-bike was weaving, while the rider says the driver never checked their blind spot. Our job involves digging up all the evidence, traffic camera footage from an intersection like Van Ness and Geary, witness statements, and accident reconstruction reports, to push our client’s share of the fault as low as possible. The goal is simple: prove the driver was more at fault to maximize what you can recover.

E-Bike Riders as Vehicle Operators: The California Vehicle Code Perspective

Lots of people get this wrong, but California law treats e-bike riders like vehicle operators, not pedestrians. The California Vehicle Code Section 21207.5 lays out specific rules for e-bikes, covering everything from speed limits to where you can ride. This is important for liability. E-bike riders are expected to obey the same traffic laws as drivers, stop at red lights, yield the right-of-way, and signal your turns. If you’re found to have broken a traffic law, like running a red light at 5th and Market and getting hit, expect your share of the blame in an accident claim to go way up. On the flip side, if a driver doesn’t yield to you when you have the right-of-way, their liability is much clearer. I find many riders, particularly new ones, just don’t know their duties under the vehicle code and think they have pedestrian-like privileges. That kind of thinking contributes to accidents and really complicates a legal claim later. Knowing the rules of the road isn’t just about safety. It protects your ability to file a successful claim if something happens.

The Critical Role of Evidence: Post-Accident Actions

The immediate aftermath of an e-bike crash is chaotic. But the actions you take right there at the scene can make or break your liability claim. Cases with solid evidence gathered on the spot have a much higher chance of success in proving who was at fault. That means you need to pull out your phone and take pictures of everything: the scene from all angles, the damage to the car and your bike, the road conditions, and any injuries you have. Getting contact information from anyone who saw what happened is invaluable, even if they only saw part of it. A witness who saw a car blow a stop sign on Lombard Street provides powerful, unbiased testimony that an insurance adjuster can’t easily dismiss. You must also report the accident to the San Francisco Police Department (SFPD) and get a police report number. The police report provides an official record and an officer’s initial take. Go to a doctor immediately, even if you feel okay, because this creates a medical record linking your injuries directly to the crash. Without that proof from the scene, it just becomes a “he said, she said” argument, which is a mess.

Uninsured/Underinsured Motorist Coverage: A Rider’s Safety Net

Here’s something most e-bike riders don’t think about until it’s too late: uninsured/underinsured motorist (UM/UIM) coverage. While you don’t have insurance on your e-bike, your own car insurance policy (or a policy from someone in your household) might extend this coverage to you when you’re riding. This coverage is a safety net when the driver who hit you has no insurance or not enough to cover your medical bills and lost income. Relying on the at-fault driver’s policy is a huge gamble. We see it all the time, a driver’s minimum liability coverage in California is just $15,000 for bodily injury, and that amount vanishes instantly with the kind of serious injuries we see in e-bike wrecks. Using the UM/UIM coverage from your own policy lets you file a claim with your own insurance company, which is often a much more direct path to getting compensated. I tell every client to check their auto policy for this feature. It can be the difference between getting your bills paid and being left with a huge financial hole after a collision.

With so many e-bikes on San Francisco’s streets, all road users need to get the liability rules straight. If you’re an e-bike rider hit by a car, knowing your rights, your duties, and what to do in the moments after a crash can completely change the outcome of your case. So, ride safe, know the law, and if you get hit, document everything. It’s the only way to protect yourself.
