Let's think about this folks.
This is a summary showing the type of violation cited as the cause of accidents involving bicycles and automobiles. The California Highway Patrol is a state organization that is responsible for traffic enforcement outside of city limits where local police departments have primary jurisdiction.
These are cases involving injury or death to the cyclist involved, so I would think that they would be of significant interest when determining strategies for reducing the number of such incidents in the future.
Note that violations were not cited in all accidents. It has not been written but should also be noted that the CHP also has the freedom to cite multiple violations, and/or violations involving both parties when indicated.
Unsafe Speed violations are typically applied "after the fact" and are determined by three factors: 1) Posted speed limits, 2) Environmental considerations at the time of the incident (darkness, rain, fog, etc.) and 3) Characteristics of the specific vehicles involved.
If person A conducts their vehicle in a manner which is completely within both the letter and spirit of the law, and person B collides with person A at least in part because they were going too fast to stop, it is likely that person B may have been traveling at an unsafe speed.
Look at the rest of the violations by bicycles and think about what the cyclists could have done to reduce the number of injuries and deaths. If they had not ridden on the wrong side of the road, made sure not to challenge when automobiles really did have the right of way and ridden in accordance with traffic signals and signs about 25% of the injuries and deaths could have prevented.
As cyclists we pay a lot of attention to how the actions of automobile drivers put us at risk. I'm not saying that we shouldn't continue to do that, but doing what we can to foster safe behavior among our fellow cyclists can also be helpful.
