What are the rules for bicycle riders in California?

This is from the

California Driver Handbook Sharing the Road with Other Vehicles Slow Moving Vehicles Animal Drawn Vehicles and Cycles



Bicyclists on public streets have the same rights and responsibilities as automobile and motorcycle drivers. Respect the right-of- way of bicyclists because they are entitled to share the road with other drivers. Here are some critical points for drivers and bicyclists to remember:

A sign telling drivers to share the road with bicyclists.
Motor vehicle drivers must:
  • Pass a bicyclist as they would a slow moving-vehicle. Pass with caution, and only when safe.
  • Look carefully for bicyclists before opening doors next to moving traffic or before turning.
  • Safely merge toward the curb or into the bike lane.
  • Not overtake a bicyclist just before making a turn. Merge first, then turn.
  • Be careful when approaching or passing a bicyclist on a freeway.
Bicyclists:
  • Must obey all traffic signals and stop signs.
  • Are lawfully permitted to ride on certain sections of freeways, in some rural areas where there is no alternate route.

  • Must ride in the same direction as other traffic, not against it.
  • Shall ride as near to the right curb or edge of the roadway as practical– not on the sidewalk.
  • May legally move left to turn left, to pass a parked or moving vehicle, bicycle, animal, make a turn or avoid debris and other hazards.
  • May choose to ride near the left curb or edge of a one-way street.
  • Should ride single file on a busy or narrow street.
  • Must make left and right turns in the same way that drivers do, using the same turn lanes. If the bicyclist is traveling straight ahead, he or she should use a through traffic lane rather than ride next to the curb and block traffic making right turns.
  • Must signal all their intentions to motorists and bicyclists near them.
  • Must wear a helmet if under the age of 18.
  • Should carry identification.
  • Shall not operate a bicycle on a roadway during darkness unless the bicycle is equipped with:
    • A brake which will enable the operator to make one braked wheel skid on dry level, clean pavement.
    • A front lamp emitting a white light visible from a distance of 300 feet.
    • A rear red reflector visible from a distance of 500 feet.
    • A white or yellow reflector on each pedal visible from a distance of 200 feet.

What should you do when you get bitten by a venomous snake?

P8140641


According to the U.S. National Institutes of Health:

1. Keep the person calm, reassuring them that bites can be effectively treated in an emergency room. Restrict movement, and keep the affected area below heart level to reduce the flow of venom.
2. If you have a pump suction device (such as that made by Sawyer), follow the manufacturer's directions.
3. Remove any rings or constricting items because the affected area may swell. Create a loose splint to help restrict movement of the area.
4. If the area of the bite begins to swell and change color, the snake was probably poisonous.
5. Monitor the person's vital signs -- temperature, pulse, rate of breathing, and blood pressure -- if possible. If there are signs of shock (such as paleness), lay the person flat, raise the feet about a foot, and cover the person with a blanket.
6. Get medical help right away.
7. Bring in the dead snake only if this can be done safely. Do not waste time hunting for the snake, and do not risk another bite if it is not easy to kill the snake. Be careful of the head when transporting it -- a snake can actually bite for up to an hour after it's dead (from a reflex).

Human speech is like a cracked kettle on which we beat out tunes for bears to dance to

 P1020325


… one had to discount, he thought, exaggerated speeches that concealed mediocre affections; as if the fullness of the soul did not sometimes overflow in the emptiest of metaphors, since none of us can ever express the exact measure of our needs, or our ideas, or our sorrows, and human speech is like a cracked kettle on which we beat out tunes for bears to dance to, when we long to move the stars to pity.

(part of the original, in French)

troisième partie , Chapitre 7, Emma à Maître Guillaumin,


"...comme si la plénitude de l'âme ne débordait pas quelquefois par les métaphores les plus vides, puisque personne, jamais, ne peut donner l'exacte mesure de ses besoins, ni de ses conceptions, ni de ses douleurs, et que la parole humaine est comme un chaudron fêlé où nous battons des mélodies à faire danser les ours, quand on voudrait attendrir les étoiles. "


- from Lydia Davis's new translation of Madame Bovary by Gustave Flaubert
