Hit by a vehicle at a crosswalk This happened today in L.A. county in los angeles (just outside culver city). I was walking my bicycle down the sidewalk on the left side of the road, saw the green light and white pedestrian icon. I hopped on, and proceeded to bike down the crosswalk slowly. A man was stopped at the red light looking left for about five seconds. I assumed he was waiting since he probably saw the pedestrians behind me and the white light. He turned right without looking right and collided with me. My bike slammed against the road, and my leg twisted a bit. I had some scrapes and scratches but I didn't land on my head. I got his information and a couple of people saw it.

He apologized, and admitted that he didn't look before turning on red.

I read online that it's illegal to cycle through a crosswalk at an intersection, and that it also wasn't illegal. (so which is it?)

My bike has some damages and i want to get my foot checked out, but what is exactly is the law in this case? I was walking and then once it was green with the pedestrian icon, i hopped on and cycled.

Thanks
I don't know the specific laws in CA for riding in a crosswalk, but here in AZ (both CA and AZ are in the USA) it is actually ambiguous. While on a bicycle, you become not a pedestrian, which in AZ means that you aren't afforded the legal protections of a pedestrian, which means that in cases like yours there is no legal recourse.

However, riding a bicycle on a sidewalk here in AZ is illegal, and for good reason.

Section 275 of the CA motor vehicle code states that the crosswalk is an extension of the sidewalk, so if riding on the sidewalk is legal where you live, then you had the right of way.

After looking around, it appears that CA has a hodge podge of local ordinances pertaining to the legality of riding on the sidewalk.

Culver city ordinance §7.04.250  RIDING ON SIDEWALKS. states


  A.   No person shall ride a bicycle upon a sidewalk within any
  business district or upon the sidewalk adjacent to any public school
  building, church, recreation center or playground or upon a walkway
  specifically designated by resolution of the City Council as closed to
  all vehicular or bicycle traffic. B.   Whenever any person is riding a
  bicycle upon a sidewalk such person shall yield the right-of-way to
  any pedestrian and when overtaking and passing a pedestrian, after
  giving an audible signal, shall at all times pass to the left of such
  pedestrian.


while the ordinance for LA county, §15.76.080 Driving or riding vehicles on sidewalk. states 


  A person shall not operate any bicycle or any vehicle or ride any
  animal on any sidewalk or parkway except at a permanent or temporary
  driveway or at specific locations thereon where the commissioner finds
  that such locations are suitable for, and has placed appropriate signs
  and/or markings permitting such operation or riding.


and for the City of Los Angeles SEC. 56.15.  BICYCLE RIDING – SIDEWALKS. states 


  
  No person shall ride, operate or use a bicycle, unicycle, skateboard, cart, wagon, wheelchair, rollerskates, or any other device
  moved exclusively by human power, on a sidewalk, bikeway or boardwalk
  in a willful or wanton disregard for the safety of persons or
  property.  (Amended by Ord. No. 166,189, Eff. 10/7/90.)
  
  
  No person shall ride, operate or use a bicycle or unicycle on Ocean Front Walk between Marine Street and Via Marina within the City
  of Los Angeles, except that bicycle or unicycle riding shall be
  permitted along the bicycle path adjacent to Ocean Front Walk between
  Marine Street and Washington Boulevard. (Amended by Ord. No. 153,474,
  Eff. 4/12/80.)
  No person shall operate on a beach bicycle path, or on an area of a beach which is set aside for bicycle or unicycle use, any bicycle
  or tricycle which provides for side-by-side seating thereon or which
  has affixed thereto any attachment or appendage which protrudes from
  the side of the bicycle or tricycle and is used or designed to carry
  another person or persons thereon.
  For the purposes of this section motorized bicycles as defined by Section 406 of the California Vehicle Code shall be included within
  the terms “motor vehicle” as defined in Section 415 of the Vehicle
  Code and as used in Section 21663 of the Vehicle Code.
  
  


So it appears that it depends...
