Frequently Asked Questions
Why do car insurance companies give a discount just for getting a quote 14 to 30 days early?
Actuarial loss data across millions of policies shows that drivers who plan ahead and shop 2 to 4 weeks before their renewal date file 11% to 16% fewer claims than drivers who buy a policy on the exact day their old coverage expires (or after receiving a traffic stop citation). Carriers reward that lower risk with an 8% to 12% Advance Quote discount.
Do I have to wait until my 6-month renewal date to switch car insurance companies?
No. In 49 states, you can switch auto insurers mid-term on any date you choose, and your previous insurer must refund 100% of your unused ('unearned') premium on a daily pro-rata basis. However, you should still set your new policy's start date 8 to 14 days in the future so you capture the Advance Quote discount.
What is 'Price Optimization' in car insurance?
Price optimization is the practice of using non-risk consumer data to estimate how much of a renewal rate increase a loyal customer will tolerate before shopping around. Although 20 states (including California, New York, Florida, Ohio, and Maryland) have banned price optimization, comparing quotes every 12 to 18 months is the only guaranteed defense against loyalty rate creep.
