California Personal Injury Law in Ontario Cases

All accident injury claims arising in Ontario are governed by California state law. The key parameters:

Statute of limitations: Two years from the date of injury under CCP section 335.1. Claims against the City of Ontario, Omnitrans, or San Bernardino County require a government tort claim within six months under Government Code section 945.4. Missing this deadline permanently bars the government entity claim.

Comparative fault: California pure comparative fault applies throughout Ontario. An injured party can recover even if partially at fault, with recovery reduced proportionally. A claimant found 30% at fault in a $100,000 case recovers $70,000.

Insurance minimums: California's mandatory minimums of $30,000 per person / $60,000 per occurrence / $15,000 property damage apply (effective January 1, 2025).

Special consideration: Ontario sits at the center of one of the world's largest inland logistics complexes. The I-10/I-15 interchange — which Ontario straddles — is a critical freight interchange for cargo moving between the Ports of Los Angeles and Long Beach and the rest of the United States. The commercial truck density on I-10 through Ontario is among the highest in California.
