Two-vehicle freeway crashes
The 5700 Bay Area freeway crashes 2013-2017 were one-third of all police-reported motorcycle crashes in the region. Of those, 20% were single vehicle (the subject of an upcoming post), 60% were 2-vehicle (the subject of this post), and 20% were 3+ vehicle (no post since the crashes are much harder to evaluate). While I refer to the other vehicles involved in these crashes as "cars", they comprise every kind vehicle on the road: cars, SUVs, vans, trucks, buses, etc. However, I have not included bike-vs-bike crashes.
Fault in two-vehicle freeway crashes was nearly equally divided between the driver (51%) and the rider (49%).
Half of crashes were sideswipes, usually caused by the car. Close to 40% were rear-end, usually caused by the motorcycle. The remainder was distributed among several different categories.
This graph shows the pre-crash movement by the party at fault. When the motorcycle was at fault, it was going straight 68% of the time. When the car was at fault, it was changing lanes 85% of the time.
Finally, here are the primary factors behind the at-fault assessment. When the motorcycle was at fault, it was due to unsafe speed 70% of the time. For the car, it was an unsafe lane change 85% of the time
