From 2018 to 2022, approximately 2,500 individuals sustained injuries annually in bicycle accidents in Southern California, with about 35 fatalities each year. These incidents predominantly occur on roads with speed limits exceeding 35 miles per hour.
They also often occur on routes with at least three lanes of traffic in each direction. A significant proportion, over half, of these accidents and injuries happen in the evening, often in areas lacking bike infrastructure, such as dedicated bike lanes.
