California is home to one of the most dangerous roads in the United States, according to a study of deadly highways by the consumer website ValuePenguin. That road is Highway 99, which runs through the Central Valley and had a rate of 62.3 fatal accidents for each 100 miles of its length from 2011 to 2015.
We have our fair share of dangerous roads in Southern California, as well. Each red dot on the map below shows the site of a fatal crash in 2016, the most recent year for which statistics are available. That year, 3,623 fatal crashes occurred in the state. The top three counties for fatalities on the road were Los Angeles (794), Riverside (262) and San Bernardino (256).
In 2016, 56 fatal crashes occurred on I-10 between Santa Monica and Beaumont, a distance of about 100 miles.
The National Highway Traffic Safety Administrations interactive map of road fatalities can be found here. The map can show locations within a few feet and has totals from 2014, 2015 and 2016. The full report on Californias roads with data from 2007 to 2016 is here.

Where crashes occur
The Transportation Injury Mapping System by SafeTREC and UC Berkeley has a collection of crash data from 2006 to 2017. One aspect of the mapping system indicates which intersections have had the most accidents by city. Here is a look at the most dangerous intersections in select cities in Orange, Riverside, San Bernardino and Los Angeles counties. Collision data is from 2015 through 2017.
