I’m confused about my insurance costs. I’m paying $600 every six months for liability only on my 2008 Chevy Cobalt, while my parents pay the same amount for full coverage on their newer vehicles, like a Jeep Wrangler and a Toyota Tundra. We’re all on the same plan, and I haven’t had any tickets or accidents. I’m 19 and female. My sister did recently get a ticket, and her insurance went up; could that be impacting my costs too? My premium used to be $400.
why am i paying the same insurance cost as my parents who have full coverage as i have liability only

It’s frustrating when insurance costs don’t seem to make sense, especially when you’re paying for liability only while your parents have full coverage. There are a few reasons why your rates might be higher:
Risk Assessment: Insurance companies assess risk based on various factors. As a younger driver, you may be seen as a higher risk compared to more experienced drivers, even if you have a clean driving record.
Family Plan Impact: Since you’re on the same plan, your sister’s recent ticket could be affecting the overall premium for the family. When one driver gets a ticket, it can raise the rates for everyone on the policy.
Vehicle Factors: The type of car you drive can impact your insurance costs too. Sometimes, even older cars like a 2008 Chevy Cobalt can have higher rates due to factors like theft rates or safety ratings compared to newer vehicles.
Policy Details: It’s possible that there are other details in your specific policy that could be influencing your rates. For example, differences in deductibles, coverage levels, or discounts.
Credit Score: In some states, your credit score can also affect insurance rates. If there are differences in credit scores among the family members, it could lead to variations in premiums.
To get a better grip on your situation, you might consider discussing it with your insurance agent. They can explain the specifics of why your rates are where they are and whether there are ways to reduce them, such as discounts for safe driving or bundling policies.
