Bicycle Laws and Regulations in San Diego

Traffic Laws for Cyclists: Bicycles Are Considered Vehicles

In San Diego, bicycles are legally considered vehicles, meaning cyclists are required to follow the same traffic laws as motorists. (Cal. Veh. Code § 21200.) Here are some key traffic laws that apply to cyclists:

• Roadway: Bicyclists traveling slower than normal traffic must stay as close as practicable to the right-hand curb or edge of the road, except when passing, turning, or avoiding hazards. Bicyclists moving at the speed of traffic can ride within the travel lane. (Cal. Veh. Code § 21202.)
• Use of Bike Lanes: When a bike lane is available, cyclists are generally required to use it. However, they may leave the bike lane to pass, make turns, or avoid hazards. (Cal. Veh. Code § 21208.)
• Obey Traffic Signals and Signs: Cyclists must stop at red lights and stop signs, yield where appropriate, and follow all posted traffic signs and signals. Running a red light or stop sign is illegal and dangerous for cyclists.
• Ride in the Direction of Traffic: Cyclists must ride in the same direction as car traffic, not against it. (Cal. Veh. Code § 21650.) This is critical for safety, as it makes cyclists more predictable to drivers. 
• Signaling: Cyclists are required to signal their intentions when turning or stopping, similar to motorists. For instance, extending the left arm straight out indicates a left turn, and a bent arm with the hand pointing up indicates a right turn.
• Riding Side by Side: Cyclists may ride side by side (two abreast) on the road, but only if it does not impede traffic. If riding in traffic, cyclists should stay in single file to allow cars to pass safely.
• Sidewalks: Local cities and counties regulate whether bicycles may ride on sidewalks. In San Diego, you can ride on sidewalks, except for in business districts. In Carlsbad, El Cajon, Vista, and Poway, sidewalk riding is prohibited.

Helmet Requirements: Safety First

Helmet use is an essential aspect of cycling safety and is mandated by law for certain age groups:

• Under Age 18: California state law requires that all cyclists under 18 years old wear a helmet while riding a bicycle, whether on streets, bike paths, or trails. The helmet must fit properly and meet safety standards set by the U.S. Consumer Product Safety Commission. (Cal. Veh. Code § 21212.) 
• Over Age 18: While helmet use is not legally required for adults over 18, it is strongly recommended. Wearing a helmet significantly reduces the risk of head injuries in an accident, and many San Diego cyclists choose to wear one for their protection.
• E-Bikes and Electric Scooters: Riders of Class 3 e-bikes (those that can reach speeds up to 28 mph) must wear helmets, regardless of age. This applies to e-scooter riders as well. (Cal. Veh. Code § 21212.) 

Helmet use is critical for safety, as head injuries are one of the most common injuries in bicycle accidents. Even experienced cyclists are encouraged to wear helmets, as the unexpected can happen on the road.

Right-of-Way Rules: Ensuring Safe Interaction with Motor Vehicles and Pedestrians

The rules governing the right of way help to prevent collisions and ensure the safe sharing of roads between cyclists, motorists, and pedestrians. Key right-of-way rules for cyclists include:

• Yielding to Pedestrians: Cyclists must always yield to pedestrians in crosswalks and on shared paths. It’s important to be cautious and courteous when approaching intersections or shared spaces, as sudden movements can cause accidents. (Cal. Veh. Code § 21950.) 
• Respecting Crosswalks: Cyclists are encouraged to walk their bikes across crosswalks if they are crossing as pedestrians. However, if riding across, they must yield to pedestrians. (Cal. Veh. Code § 21950.) 
• Right of Way in Bike Lanes: When riding in a bike lane, cyclists have the right of way over motor vehicles that may cross the lane to turn. However, it’s essential for cyclists to remain alert to avoid conflicts with turning vehicles.
• Passing and Being Passed: When riding on a roadway without a bike lane, cyclists should stay as close to the right as is safe. Drivers passing cyclists must provide at least three feet of clearance, as required by California’s “Three Feet for Safety” law.
• Turning and Merging: When making a left turn, cyclists should merge into the left-turn lane, following the same rules as vehicles. It’s crucial to signal intentions early and be aware of traffic behind and beside them.

Right-of-way rules are essential for maintaining a predictable flow of traffic and reducing the likelihood of accidents involving cyclists and other road users.

Night Riding and Visibility: Lights and Reflectors Are Required by Law

Visibility is a significant concern for cyclists, especially when riding at night or in low-light conditions. To enhance safety and visibility, San Diego enforces specific requirements:

• Front Light: Cyclists must equip their bicycles with a white light visible from at least 300 feet when riding in the dark. (Cal. Veh. Code § 21201.) This helps motorists see cyclists approaching or crossing intersections.
• Rear Reflector: Bicycles are required to have a red reflector on the rear, visible from 500 feet when illuminated by headlights. (Cal. Veh. Code § 21201.) A rear red light, while not legally required, is highly recommended for added visibility.
• Pedal and Wheel Reflectors: Bicycles must have reflectors on both the pedals (or the cyclist’s shoes) and the side of the wheels to ensure visibility from different angles. (Cal. Veh. Code § 21201.) 

Following these visibility laws helps prevent nighttime accidents, which often occur because drivers fail to see cyclists in the dark. Investing in high-quality lights and reflective gear can make a big difference in cyclist safety.

Additional Safety Recommendations: Best Practices for San Diego Cyclists

While not necessarily laws, several best practices are recommended for cyclists in San Diego:

• Stay Alert and Avoid Distractions: Just like drivers, cyclists should avoid distractions like headphones or cell phones that take their attention away from the road. Like drivers, cyclists are prohibited from wearing headphones in both ears while riding. (Cal. Veh. Code § 27400.) 
• Be Aware of “Dooring”: Cyclists riding near parked cars should stay far enough to avoid being hit by an opening car door. Motorists are encouraged to use the “Dutch Reach” (opening the door with their far hand) to check for approaching cyclists.
• Follow Safe Passing Protocols: If passing another cyclist or pedestrian on a path, announce your intentions verbally or with a bell.
• Alcohol and Drugs: Bicyclists may not ride under the influence of alcohol or drugs. (Cal. Veh. Code § 21200.5.)
