As bicycle-friendly as some parts of the state are, significant numbers of accidents involving cyclists take place on California roadways. In 2013 alone, bike riders accounted for almost 5 percent of all traffic fatalities in the state, which was more than double the national average. In the three years prior, the number of such fatalities rose by almost 20 percent nationwide.
According to analysts, cycling accidents may result in more serious injuries when they involve riders decelerating rapidly. These types of incidents can cause a cyclist's brain to impact the inside of their skull and result in cerebral trauma. Some victims even sustain fractured skulls, spinal cord damage or external injuries due to sliding friction.
