California has one of the largest populations of cyclists in the nation, thanks to its mild climate and urban commuting culture. Unfortunately, it also ranks among the highest states for bicycle accidents and fatalities. Understanding the data helps highlight the dangers cyclists face and the importance of legal protection when accidents happen.
