How to Choose the Best Insurance Company in California
The cheapest insurance company isn’t automatically the best one. Before buying a policy, consider these factors.
1. Compare Multiple Quotes
Get quotes from several insurers instead of choosing the first company you find.
Rates can differ substantially between companies for the same driver.
2. Check Coverage Limits
Don’t compare policies based only on the monthly price. Make sure you’re comparing similar liability limits, deductibles, and optional coverage.
3. Look for Discounts
Ask insurers about discounts for things such as:
- Safe driving
- Multiple vehicles
- Bundling policies
- Vehicle safety features
- Defensive driving courses
- Paying premiums electronically or in full, where applicable
4. Consider Customer Service
Price matters, but so does the insurer’s ability to handle claims and provide support.
5. Check the Insurer’s Financial Strength
Financial strength can provide additional confidence that an insurer has the resources to meet its obligations.
California’s Department of Insurance publishes market-share information for licensed property and casualty insurers, which can also be useful when researching the insurance market.
