How common are fatal bike crashes in California?
In California, a total of 145 cyclists were killed in motor vehicle crashes in 2023, according to a 2025 study by UC Berkley’s Safe Transportation Research and Education Center.
Los Angeles, San Bernardino and Sacramento counties reported the highest numbers of fatalities.
According to the study, unsafe speed was a factor in 16.5% of California bicycle crashes resulting in deaths or serious injuries, while vehicle right-of-way was involved in 16.3% of crashes and improper turning played a role in 15%.
Other key factors included traffic signs and signals.
Here’s rules of the road for cars and bikes in California:
Can cars pass bikes on the road in California?
Previously, California law allowed cars to pass bicycles at a safe distance of no less than three feet.
However, that rule was “difficult to enforce and not enough space for comfort in some situations,” California Bicycle Coalition.
Assembly Bill 1909, also known as the OmniBike Bill, makes it “easier for police to cite drivers who fail to give bikes room for safety,” the Sacramento-based nonprofit organization said.
AB 1909, which went into effect in 2024, additionally requires drivers to “move over to an adjacent lane of traffic … if one is available, before passing or overtaking the bicycle.”
The same rule applies when you’re passing another motor vehicle, according to Steven M. Sweat Personal Injury Lawyers in Los Angeles.
If an open lane is not available, you must “slow down and wait” until it is safe to pass the cyclist with at least three feet of clearance, Los Angeles law firm Rose, Klein & Marias LLP said.
It’s important to “slow down to a reasonable and prudent speed before passing,” Carlsbad’s Law Firm of Richard L. Duquette said on its website. “In other words, no tailgating or reckless passing is allowed.”
You could be found in violation of the law if you begin a pass, then “prematurely” move back into the lane, the Law Firm of Richard L Duquette said.

Drivers are not allowed to stop or park in bike lanes, according to the California Bicycle Coalition.
What are the penalties for improper passing?
If you’re caught improperly passing a bike on the road, you could face up to $982 in fines, according to Steven M. Sweat Personal Injury Lawyers.
You could also get a point on your California driver’s license, and may be required to go through a license re-exam.
Drivers who strike or sideswipe cyclists while passing are “presumed negligent” and can face litigation for personal injury claims, the Southern California law firm said.
Where are bikes allowed on California roads?
In California, cyclists are allowed to ride anywhere on the road as long as they are traveling at the same pace as cars, The California Bicycle Coalition said.
Bicyclists should stay near the right side of the road or in a bike lane if they cannot keep up with car traffic.
Although some roads may have separated bike lanes, bicyclists can ride outside these lanes “for any reason,” the California Bicycle Coalition said.
There are some limits, however.
Bikes are not allowed to on freeways or expressways, and cyclists cannot pass through tolls unless the signs nearby dictate otherwise.
According to California’s Vehicle Code, bikers can ride on the road when passing other bicyclists, making a left-hand turn and avoiding hazards.
Cyclists must obey traffic lights and signs and go in the direction of traffic, traveling on the right side of the roadway except when making a left turn.
Bicyclists may be allowed to ride on sidewalks in certain cities and counties as local governments oversee these regulations.
Are there exceptions for e-bikes?
E-bikes are not considered motor vehicles under California law, which means cyclists must follow standard bike laws.
However, e-bikes are not allowed to operate in bike lanes or bike and hiking trails.
