It’s important to know these laws and rules for your safety, the safety of other cyclists and the safety of drivers as well. Are bicycle helmets required in California?

Invest in Yourself:

Before we move into bike safety rules in California, consider investing in yourself. You will want to:

• Cyclist Helmet: Protect your head
• Rear Light [At least 100 Lumens]: Allow a car see when they are coming behind you
• Rear View Mirror: See when a car is coming behind you
• Bicycle Car Awareness Radar: Know when a car is coming behind you

This will be your survival kit for riding in the Bay area. Many places in the bay area have cycling friendly rules, though your safety is still paramount, and it is important to have these items to make sure you’re always safe

Are Bicycle Helmets Required in California?

No, bicycle helmets are not required in California if you are over the age of 18. Bicycle helmets are required if you are under the age of 18. So, if you are over the age of 18, the choice of wearing a bicycle helmet is an option available to you. However, we would urge you to wear a helmet. 

Wearing a helmet in many nationally recognized races is compulsory and although northern California is one of the most biker friendly places in the states regarding traffic laws, bike routes and the general temperament of drivers; a helmet typically is the deciding factor that allows a cyclist to walk away from a nasty fall with a large amount of scrapes, bruises and lashes versus the possibility of a fatal accident.

Helmets:

Why are Bicycle helmets useful?

There were many cyclists who believed that wearing a helmet was an inconvenience – like a car seatbelt in the 80’s. The times have changed and is now understood that Bicycle helmets are very useful. The role of a helmet is to allow the impact of whatever object against it to take the force and allow it to reverberate through the enter surface area of the helmet and padded material before approaching the skull. Not only does this spread the force out evenly across the head, but it also decreases the amount of force substantially which ultimately hits the head. This is what is the factor that makes a hammer to a helmet become a loud annoyance as opposed to a hospital visit.

The reality is that any type of fall at any speed when you are mounted on your bicycle can lead to a potentially life altering brain injury.

Can I cycle without a helmet?

It is recommended that you do not cycle without a helmet, even it is allowed in California after the age of 18. Cycling helmets will protect your head from skull and brain injury, and help you avoid life altering events if you were to fall.

Road Rules:

Is it illegal to ride a bike on the Sidewalk in California?

No, it is not illegal to ride a bike on a sidewalk in California. Typically, if you are a child, or riding a bicycle that can not approach high speeds then it is not recommended to ride on the sidewalk. Many sidewalks have pedestrians who are not expecting a cyclist. Further for your own safety many cars are not expecting any moving objects to move from the sidewalk onto the road. It is far safer to stay on the shoulder, bike lane, or in the road with a capable backlight, than to ride a bike on the sidewalk in California.

Further, this also includes riding in the opposite direction. It is far more dangerous for you to ride the opposite direction of the road. The rational of being able to see a car coming will do you no good if they need to change a lane and are not looking for a cyclist coming in a direction towards them. It is very unsafe to do so. If concerned about seeing cars, car radars that can detect a car from 400+ feet away and bicycle mirrors are available to cyclists.

Can Cyclists Ride in the Middle of the Road in California?

Yes, cyclists can ride in the middle of the road in California. As long as you are not on a highway, you are able to ride in the middle of the road. However, you should take advantage of this ability cautiously. There are some roads where you won’t see a car, or civilization for hours and it is advantageous for you to take the entire road. There are other options as well in the bay area where traffic is not for the faint of heart. Use your senses and wits to make the right decision for your own safety.

Do cyclists have to let cars pass?

No, there is no law that states a cyclist must let cars pass. However, if you are on a one lane road and you noticed that 4 cars are riding politely behind you, it is best practice to allow the cars to pass when it’s safe.  

Conclusion

Riding with a helmet is entirely important to keep yourself safe. There is no law in California stating that it is compulsory to ride with a helmet, though it is more than recommended that you should. A collision at any speed – including at 0mph can lead to a life altering injury when on a bike, so it is in your best interest to think about the safety as you ride.
