The Most Dangerous Roads in the Inland Empire — 2025 Data

The Inland Empire — San Bernardino and Riverside Counties — has some of the most dangerous roads in California. With high truck traffic, sprawling freeway interchanges, and rapidly growing population, serious accidents happen here every day. Knowing the most dangerous corridors can help you drive more defensively — and if you've been injured on these roads, knowing their history can strengthen your claim.

Interstate 10 (San Bernardino Freeway)

The I-10 through San Bernardino County is one of the deadliest freight corridors in the United States. Stretching from Los Angeles through Fontana, Ontario, and into the desert, it carries enormous volumes of commercial truck traffic 24 hours a day.

Highest-risk segments:

• The I-10/I-15 interchange in Ontario/Fontana — one of the busiest and most crash-prone intersections in the IE
• The Fontana/Rancho Cucamonga stretch between Haven Ave and the I-15 merge
• The Banning Pass near Cabazon — high winds and steep grades cause frequent truck rollovers

Interstate 15 (Barstow Freeway / Ontario Freeway)

The I-15 runs from San Diego through the heart of the Inland Empire to Las Vegas. It serves massive warehouse and logistics traffic, with hundreds of semi-trucks per hour in peak periods.

Highest-risk segments:

• The Cajon Pass (north of Devore) — steep 6%% grade, frequent runaway truck accidents, and weather-related multi-car pileups
• The I-15/I-215 split in Murrieta/Temecula — high-volume merging traffic
• The Jurupa Valley/Riverside stretch near the 60 interchange

Interstate 215

The I-215 cuts through San Bernardino, Colton, Riverside, Perris, and Murrieta. It serves as a major commuter and freight route connecting the northern and southern IE.

Highest-risk segments:

• The San Bernardino/Colton interchange near the I-10 junction
• The Perris Boulevard corridor — high pedestrian and bicycle conflict zones
• Construction zones between Murrieta and Menifee have elevated crash rates

State Route 60 (Pomona Freeway)

SR-60 links Los Angeles County to the Inland Empire through Pomona, Ontario, and Riverside. It is frequently congested and has a high rate of rear-end crashes during peak commute hours.

State Route 91 (Riverside Freeway)

SR-91 connects Orange County to Corona and Riverside. The Orange County/Riverside County border crossing is consistently ranked among the most congested freeway segments in Southern California, with stop-and-go traffic creating constant rear-end collision risk.

Surface Street Hotspots

Beyond the freeways, several Inland Empire surface streets generate disproportionate crash numbers:

• Foothill Blvd (Rialto / Fontana) — high-speed arterial with multiple at-grade crossings
• Baseline Road (San Bernardino / Highland) — frequent pedestrian accidents
• Valley Blvd (Colton / Bloomington) — truck traffic mixing with residential streets
• Perris Blvd (Moreno Valley) — high pedestrian and cyclist fatality rate
• Van Buren Blvd (Riverside) — multiple fatal crash clusters

Common Causes of IE Freeway Accidents

• Distracted driving (phone use) — accounts for est. 20%% of all crashes
• Truck driver fatigue (HOS violations on I-10 and I-15)
• Speeding — particularly in the 75–90 mph range on I-10 and I-15
• Drunk and drugged driving — especially late night on weekends
• Sudden braking in construction zones
• Tire blowouts from large commercial vehicles leaving debris
• Wrong-way drivers on I-215 and SR-60
