  1. Bicyclists' Code of Conduct

    1. Never ride against traffic.
    2. Ride as near to the right as practicable*.
    3. Stop at stop signs and red lights*.
    4. Honor others' right of way.
    5. Use hand signals.
    6. With traffic, ride single file.
    7. Be predictable; don't weave.
    8. Follow lane markings.
    9. Don't needlessly block the road*.
    10. Use lights at night.

    *Note that the two most common offenses of bicyclists are running stop signs, and groups of cyclists blocking the road.

    1. Stop at stop signs/lights: Stop at all stop signs and red lights. If two vehicles arrive at an intersection at the same time, the vehicle to the right has the right of way. Politely indicate others' right of way with a hand gesture. For your own safety, never insist on your own right of way. Pedestrians always have the right of way. Your courtesy will be noticed and appreciated by other road users.

    2. Group riding: a) The California Vehicle Code (CVC sec. 21202(a) and sec. 21750) states that bicyclists are entitled to the full width of the road for at least purposes of overtaking, left turns, avoiding obstacles, when approaching a place where a right turn is authorized, and when riding in a substandard width lane. Generally, it is prudent to stay as far to the right as practicable. When riding with others do not block traffic and ride single file. Be aware of other road users at all times. b) When stopping for a stop sign in a group, queue up in small numbers and proceed when it is your turn, allowing other road users their right of way. The idea is to cross the intersection as safely and quickly as possible without testing the patience of other road users. Self-policing and courteous riding will go far.

    Wear a helmet, bright clothing, and keep your bicycle in good working order. Helpful hint: Modern, good quality brakes along with good technique make stopping at stop signs much easier.

    Bicyclists and any passengers under 18 years of age (including children in attached bicycle seats or in or on towed trailers) are required to wear a properly fitted and fastened bicycle helmet. This helmet must be labeled to show that it meets applicable safety standards.

    Youngsters under the age of nine lack the physical and mental development to interact safely in a complex traffic environment.

  2. Laws and Safety Tips
  3. Bicyclists on public roadways assume all the same rights and responsibilities as automobile drivers, and are subject to the same state laws and local ordinances. For everyone's safety, observe these bicycling rules:

    • BE PREDICTABLE

    • Never ride against traffic. Motorists aren't looking for bicyclists riding on the wrong side of the road. Many other hazards threaten the wrong-way rider.

      Obey traffic signs and signals, and basic right-of-way rules. Cyclists must drive like motorists if they want to be taken seriously. Doing so is also the safest behavior. When approaching a stop sign or red light, you are required to come to a complete stop and proceed only when safe to do so.

      Use hand signals. Hand signals tell other road users what you intend to do. Signal as a matter of law, of courtesy, and of self-protection.

      Ride in a straight line. Whenever possible, ride in a straight line, to the right of traffic but about a car door's width away from parked cars.

      Don't weave between parked cars. Don't ride to the curb between parked cars, unless they are far apart. Motorists may not see you when you try to move back into traffic.

      Follow lane markings. Don't turn left from the right lane. Don't go straight in a lane marked "right-turn-only." Stay to the left of the right-turn-only lane if you are going straight.

      Choose the best way to turn left. There are two ways to make a left turn. 1) Like an auto. Signal, move into the left lane, and turn left. 2) Like a pedestrian. If you are with-in a designated crosswalk, dismount and walk your bike across.

    • BE ALERT

    • Watch for right-turning traffic. Motorists turning right may not notice cyclists on their right. Watch for any indications that a motorist may turn into your path. When approaching intersections try to stay far enough from the curb to allow cars to turn right on your right. Motorists may not look for or see a bicycle passing on the right. Look back before you pass or merge. Leave a good 3-4 feet when passing a pedestrian or another bicyclist. A rear-view mirror is a good idea, but don't rely on it alone.

      Respect pedestrian's rights. Pedestrians have the right of way. Don't cross sidewalks via driveways without yielding to pedestrians. Don't ride on sidewalks. Use the street, bike lane, or bike path. Give a warning: use your bike bell, or call out "Passing on your left".

      Keep both hands ready to brake. You may not stop in time if you brake one-handed. Allow extra distance for stopping in rain, since brakes are less efficient when wet.

      Avoid road hazards. Watch out for streetcar tracks and old railroad tracks. Cross them perpendicularly. Avoid parallel-slat sewer grates, slippery manhole covers, oily pavement, gravel, and potholes. All are hazardous, especially when wet.

      Watch your speed. Observe posted speed limits and obey the basic speed law: Never ride faster than is safe under the existing conditions.

    • BE EQUIPPED

    • Use good lights at night. Front light, wheel and pedal reflectors are required. The front light must be visible from 300 feet. Use a rear red light for enhanced visibility. Wear light-colored or reflective clothing.

      Ride a well-equipped bike. Be sure your bike is adjusted to fit you properly. For safety and efficiency, outfit it with bells, rear-view mirrors, racks or baskets, lights and reflectors.

      Be visible. Wear light or bright-colored clothing.

      Wear a helmet when you ride. Helmets that have passed Snell Foundation or ANSI Z90.4 standard crash tests should be worn. Bike helmets may need to be replaced after a fall. All youths 18 and under must wear a bicycle helmet when operating a bicycle or when riding as a passenger.

      Passengers must ride on a separate attached seat. If the passenger is 4 years old or younger, or weighs 40 pounds or less, the seat shall adequately retain the passenger in place and protect him/her from the bike's moving parts. In addition, this passenger must wear a helmet of good fit, fastened securely, and meet ANSI Z90.4 helmet standards or Snell Memorial Foundation's 1984 Standard for protective headgear.

      Keep your bike in good repair. Maintain your bike in good working condition. Check brakes regularly and keep tires properly inflated. Learn to do routine maintenance yourself or leave it to the experts at your local bike shop.

      Get in shape. Before riding, spend a few minutes stretching your legs and body. If you are not an experienced cyclist, start with short trips and work up to longer distances.

    • RIDE SAFELY AND COURTEOUSLY

    • Probably the single most important thing a bicyclist can do to earn bicyclists greater respect on the road is to obey stop signs and traffic signals.

  4. Motorist Protocol Regarding Bicyclists
  5. From the California Driver Handbook

    SHARING THE ROAD WITH OTHER VEHICLES: BICYCLES

    Bicycle riders on public streets have the same rights and responsibilities as automobile drivers. Drivers of motor vehicles must treat bicycle riders the same as drivers of other motor vehicles. Bicyclists are not out of place on the roadway -- they are part of the traffic and share the road with other drivers. They must obey stop signs, traffic lights, and most other traffic laws and signs. Special care must be used near them because any accident with them will probably result in serious injury. This means that automobile drivers must leave safe passing room and must not turn so close to them that the bicyclist is in danger of being hit.

    Although bicyclists will normally ride near the right hand curb or edge of the roadway, they can legally move left to turn left, to pass another vehicle or bicycle, or to avoid debris or parked cars. They may have to swerve to avoid a car door suddenly opening. Expect any of these moves by bicyclists in a main traffic lane. Remember, on one-way streets, this can be the left hand lane.

    When the lane is too narrow to pass a bicyclist safely, wait until the next lane is clear and give the bicyclist all the rights of any other slow moving vehicle.

    A motorist parked at a curb must not open a door on the traffic side of a vehicle without looking for other vehicles, including bicycles or motorcycles.

    Bicycle riders may give right turn signals with their right arm held straight out, pointing right. Remember, bicycles are small and sometimes drivers do not see them.

    Note that the two most common misconceptions of motorists
    are assuming that roads were built for cars only,
    and that bicyclists are not paying their way.

  6. California Vehicle Code regarding bicycles
    1. CALIFORNIA VEHICLE CODE SECTION 21200-21212

For purposes of this section, a "substandard width lane" is a lane that is too narrow for a bicycle and a vehicle to travel safely side by side within the lane. (4) When approaching a place where a right turn is authorized. (b) Any person operating a bicycle upon a roadway of a highway, which highway carries traffic in one direction only and has two or more marked traffic lanes, may ride as near the left-hand curb or edge of that roadway as practicable.

      21203. No person riding upon any motorcycle, motorized bicycle, bicycle, coaster, roller skates, sled, or toy vehicle shall attach the same or himself to any streetcar or vehicle on the roadway.

      21204. (a) No person operating a bicycle upon a highway shall ride other than upon or astride a permanent and regular seat attached thereto. (b) No operator shall allow a person riding as a passenger, and no person shall ride as a passenger, on a bicycle upon a highway other than upon or astride a separate seat attached thereto. If the passenger is four years of age or younger, or weighs 40 pounds or less, the seat shall have adequate provision for retaining the passenger in place and for protecting the passenger from the moving parts of the bicycle.

      21205. No person operating a bicycle shall carry any package, bundle or article which prevents the operator from keeping at least one hand upon the handlebars.

      21206. This chapter does not prevent local authorities, by ordinance, from regulating the registration of bicycles and the parking and operation of bicycles on pedestrian or bicycle facilities, provided such regulation is not in conflict with the provisions of this code.

      21207. (a) This chapter does not prohibit local authorities from establishing, by ordinance or resolution, bicycle lanes separated from any vehicular lanes upon highways, other than state highways as defined in Section 24 of the Streets and Highways Code and county highways established pursuant to Article 5 (commencing with Section 1720) of Chapter 9 of Division 2 of the Streets and Highways Code.
