The Los Angeles Police Department offers training in safe bicycling to its officers, and now the video is available on YouTube. The primary thrust of the video is the way traffic laws in California (and almost all other states) apply equally to automobiles and bicycles.
The organization of the video is fitted for classroom use: a short presentation of a unified concept of traffic law is followed by a set of multiple-choice questions. And its strength is that the video waits for the incorrect answers to be corrected before continuing to the next concept.
