Common Euclid Avenue Accident Types

T-Bone

Broadside Collisions

Red-light running at Euclid/Holt and Euclid/Foothill causes severe T-bone crashes. The struck vehicle's occupants have no protective crumple zone on the side door — resulting in serious injuries including fractured pelvis, TBI, and internal injuries.

Pedestrian

Pedestrian Knockdowns

Downtown Ontario's commercial core along Euclid Ave sees significant pedestrian activity. Drivers failing to yield at crosswalks — especially near Ontario City Hall and the Ontario Convention Center — cause serious pedestrian accident injuries.

Left-Turn

Left-Turn Failures

Left turns across Euclid Ave traffic are a major accident cause. Drivers misjudging oncoming vehicle speed — particularly motorcycles — cause serious broadside accidents at nearly every major Euclid Ave cross-street.

Truck

Commercial Vehicle Conflicts

The Euclid Ave / I-10 interchange area sees heavy truck traffic serving Ontario's industrial and logistics zone. Trucks making wide turns and merging onto I-10 on-ramps create dangerous conflicts with passenger vehicles.
