California collision coverage will pay for the repairs to a vehicle if the owner is the one at fault in the accident. Ideally, if the other party is at fault, their property damage liability insurance will cover the cost of repairs. If you have questions about insurance coverage or your legal rights after a crash, an experienced car accident attorney can help you understand your options. Collision coverage is usually the most expensive type of auto insurance and generally pays for damage to your vehicle caused by the owner, regardless of fault.
