Car Accidents in Riverside: Freeways, Arterials and Your Claim

Riverside is the largest city in the Inland Empire and its county seat. Three freeways define it: SR-91 carries Orange County commuters through the city’s center and the Santa Ana Canyon, SR-60 crosses the north side toward Moreno Valley, and I-215 runs along the east toward San Bernardino and Perris. The 60/91/215 interchange east of downtown is one of the busiest junctions in Riverside County.

Riverside’s arterials are long and wide. Van Buren Boulevard, Magnolia Avenue, Arlington Avenue, University Avenue, Alessandro Boulevard and Central Avenue carry commuters, UC Riverside students, and traffic to the March Air Reserve Base area and the warehouses of the eastern county. Long distances between signals and high posted speeds contribute to severe intersection collisions.
