I-10 San Gorgonio Pass Accident Guide: Banning, Beaumont and Cabazon

Where the Pass Begins and Ends

• The summit is in Beaumont, just east of the junction of I-10 and State Route 79, at about 2,600 feet. SR-60 merges into I-10 in Beaumont too.
• Banning is about 6.5 miles east of the summit. SR-243 starts here and climbs to Idyllwild.
• Cabazon is where the passage between the mountains is narrowest. It’s home to the Cabazon Dinosaurs, Desert Hills Premium Outlets and Morongo Casino, Resort & Spa, all of which send shoppers and visitors on and off the freeway.
• The east end is generally taken to be the junction of I-10 and Highway 111 near Whitewater Canyon. From Cabazon east, the freeway drops steeply toward the desert.

The speed limit on I-10 throughout Riverside County is 70 mph.

Wind

The tall ranges on both sides make the pass one of the windiest places in the United States. That’s why the San Gorgonio Pass Wind Farm is here. The CHP’s Indio office tells westbound visitors they’re entering its area “when you see windmills.”

The National Weather Service regularly issues wind alerts for the “San Gorgonio Pass near Banning.” Its October 15, 2026, High Wind Warning called for gusts of 50 to 65 mph and warned that “travel will be difficult, especially for high profile vehicles.” Wind can push trucks, RVs, trailers and vans out of their lanes, and it can blow sand across roads on the desert side.

Trucks and Visitors on the Same Grade

I-10 is a coast-to-coast trucking route, and through the pass it carries big rigs alongside commuters, RVs, and weekend traffic to Palm Springs and the festivals in Indio. Trucks slow on the climb westbound and pick up speed on the descent eastbound, so speed differences between lanes can be large. Add casino and outlet traffic at the Cabazon exits, and lane changes come fast.

Under California law, every driver must drive at a speed that is safe for conditions, including wind. A trucking company may also be responsible for how its driver handled the conditions. See our truck crash lawyer page.

Who Writes the Report

• CHP San Gorgonio Pass Area, 195 Highland Springs Avenue, Beaumont, (951) 846-5300. It covers more than 860 square miles, including Banning, Beaumont, Cabazon, Hemet, San Jacinto and Winchester.
• CHP Indio Area, 79650 Varner Road, Indio, (760) 772-5300, patrols I-10 farther east into the Coachella Valley.

CHP collision reports cost $10 for 1 to 25 pages. If your crash was on a city street after you left the freeway, Banning or Beaumont police may have the report instead. Our Banning and Beaumont pages explain how to request those.

After a Crash in the Pass

1. Get out of traffic if you can do so safely, and call 911. Shoulders are narrow in places and traffic is fast.
2. Save the weather alert on your phone and note the time. Wind conditions can change in minutes.
3. Photograph the vehicles, any truck’s company name and DOT number, and the road.
4. Get names of witnesses before they drive off.
5. Don’t give a recorded statement to the other driver’s insurer before talking to a lawyer. See insurance adjusters after a car accident.

California uses comparative negligence, so you may recover even if you were partly at fault. Most injury lawsuits must be filed within two years. See the statute of limitations for car accidents in California.

Where the Case Is Filed

It depends on where the crash happened. Under the Riverside Superior Court’s civil filing order (effective August 1, 2026), unlimited civil cases from Banning, Beaumont and Cabazon ZIPs go to the Riverside Historic Courthouse, and limited civil cases go to the Moreno Valley Courthouse. Cases from North Palm Springs and the rest of the Coachella Valley go to the Palm Springs Courthouse.
