Car Accidents in Riverside County

Riverside County stretches 180 miles from the Orange County line to the Arizona border and has grown faster than almost any county in California, with 2.4 million residents and some of the state’s longest commutes. The SR-91 through Corona and Riverside, the I-15 from Corona to Temecula, the SR-60 through Moreno Valley and the I-215 through Perris and Menifee carry commuters toward Orange and Los Angeles counties and trucks toward the warehouses of the Inland Empire. The I-10 through the Coachella Valley carries desert resort and interstate traffic. The combination of long high-speed commutes, heavy truck volumes and rapidly built suburbs produces a distinctive mix of collisions.

The county has one of California’s highest uninsured-driver rates and, in the Office of Traffic Safety rankings, several cities consistently rank poorly for crashes involving alcohol, speed and unrestrained occupants. Many of its fastest-growing cities are policed under contract by the Riverside County Sheriff’s Office, which changes how reports are obtained.

Who investigates and where claims are filed

Freeway collisions are investigated by CHP’s Inland Division: the Riverside area office covers SR-91, SR-60 and I-215 around the city of Riverside and Moreno Valley; Temecula covers I-15 and I-215 in the southwest county; Indio covers the I-10 and the Coachella Valley; Blythe covers the eastern desert; Beaumont covers the San Gorgonio Pass.

City streets are policed by independent departments in Riverside, Corona, Murrieta, Hemet, Beaumont, Banning, Cathedral City, Desert Hot Springs, Indio, Palm Springs, Menifee (since 2020) and a few others. Moreno Valley, Temecula, Perris, Lake Elsinore, Jurupa Valley, Eastvale, Norco, Wildomar, Canyon Lake, San Jacinto, Coachella, La Quinta, Palm Desert, Rancho Mirage and Indian Wells contract with the Riverside County Sheriff’s Office; those reports come from the Sheriff’s station serving the city.

Injury lawsuits are filed in the Superior Court of California, County of Riverside. Unlimited civil cases are heard at the Riverside Historic Courthouse and the Palm Springs and Murrieta (Southwest Justice Center) courthouses depending on where the crash occurred. Government claims against the county go to the Clerk of the Board; against a city, to that city clerk; against the Riverside Transit Agency or SunLine Transit, to the agency.

Trauma and hospital care

Riverside University Health System Medical Center in Moreno Valley is the county’s Level I trauma center. Riverside Community Hospital (Level I), Desert Regional Medical Center in Palm Springs (Level I for the Coachella Valley) and Inland Valley Medical Center in Wildomar (Level II) complete the network. Loma Linda University Medical Center in neighboring San Bernardino County also receives serious Riverside County trauma, especially pediatric cases.

Collision patterns in Riverside County

SR-91 and I-15 congestion collisions

The SR-91 through Corona is among the most congested corridors in the country, and its interchange with the I-15 produces constant rear-end and lane-change collisions. See rear-end accidents and Corona rear-end collisions.

Truck traffic

The SR-60 and I-215 through Moreno Valley and Perris serve some of the nation’s largest logistics centers, including the Skechers and Amazon facilities and the March Inland Port area. See truck accidents.

Impaired driving

Temecula wine country and the Coachella Valley’s resort and festival calendar produce elevated DUI collision counts. See drunk driving accidents and Temecula DUI collisions.

Motorcycle crashes

The Ortega Highway (SR-74), SR-243 to Idyllwild, SR-74 through the Santa Rosa Mountains and the long straight desert highways attract riders and produce serious motorcycle collisions. See motorcycle accidents and Riverside motorcycle collisions.

Uninsured drivers

Riverside County’s uninsured rate is among the state’s highest, making UM/UIM coverage decisive in many claims. See uninsured motorist accidents.

Fractures and serious orthopedic injury

High-speed desert and freeway crashes and motorcycle collisions produce a large share of fracture claims. See fractures and Riverside fracture claims.

Riverside County questions

My crash was in Temecula or Moreno Valley. Who has the report?

Both cities contract with the Riverside County Sheriff’s Office, which operates as the Temecula Police Department and Moreno Valley Police Department. Request the report from the Sheriff’s station serving that city. Freeway crashes in either city are CHP reports.

Which courthouse hears a Riverside County injury case?

The Riverside Historic Courthouse for most of the western county, the Southwest Justice Center in Murrieta for the Temecula Valley, and the Palm Springs courthouse for the Coachella Valley, depending on where the crash occurred.

Does Riverside County really have more uninsured drivers?

Studies of uninsured rates by zip code consistently show Inland Empire communities above the statewide average. In practice, UM/UIM claims against the injured person’s own policy are a larger share of claims here than in coastal counties.
