Costco auto insurance?

a friend of mine the other day told me that she pays 90 dollars on her car insurance and she is 16 years aged. I just wanted to know if in that is a catch because it sounds too good to be true.
Answers:
Is that 90 dollars per month or per week? Or conceivably her parents pay most of the insurance and she only pays 90 dollars. It's true that feminine drivers under age 21 pay smaller amount for car insurance than males.
