In Oregon, fault in a car accident is determined through a combination of police reports, witness statements, and evidence from the accident scene. Oregon follows a “modified comparative negligence” rule, meaning that if you are found to be more than 50% at fault, you cannot recover damages. Insurance companies and legal professionals analyze the details to establish liability. It’s crucial to gather as much evidence as possible, including photos, videos, and contact information of witnesses, to support your claim. Consulting with an experienced Oregon car accident attorney can also help navigate the complexities of fault determination and ensure you receive fair compensation.
