Stanford Right Hook warning sign

Warning sign at Stanford University. Taken from traffic engineer and cyclist advocate Robert Shanteau.


The city of San Francisco requested permission for an experimental sign on Market @ Octavia warning cyclists of "prohibited right turns", where motorists illegally turn right on Octavia and often hook cyclists passing on the right, in spite of the presence of signs, stripes and markings, posts and even a concrete median.
