Does credit history determine auto insurance rates?

It depends on the state where you live. Most states allow auto insurance companies to use credit to determine your risk.

Excellent credit generates cheap auto insurance because the insurance company connects an excellent credit score to a low risk of filing claims. But bad credit does the opposite.

Let’s examine how the top car insurance companies calculate rates based on credit.

Full coverage auto insurance is the most expensive, but it provides the most coverage. Liability insurance is required in most states but has the least coverage.

Collision and comprehensive are optional, but they cover vehicle damage in incidents.

Collision insurance covers an accident regardless of fault, and comprehensive coverage pays for damage from unforeseen accidents, such as sudden fires, flooding, storms, vandalism, and car theft.
