Average car insurance rates by age group range from $716 per year for 45-year-old drivers to $3,343 per year for drivers who are 16 years old. Car insurance rates are highest for teens and seniors, on average, because they are considered high-risk due to an increased likelihood of accidents and expensive claims.

Auto insurance scores are ratings based on information from credit reports that insurers use to estimate how likely drivers are to file a claim. Insurance scores have different ranges depending on the scoring company, but lower scores always mean that drivers are riskier to insure and will likely pay a higher premium.
