For 17-year-olds, Nationwide emerges as the cheapest car insurance provider when adding the driver to a family policy, with average monthly rates of $224 and yearly rates of around $2,685. In contrast, the average car insurance premium for a family plan for a 17-year-old driver is $252 monthly, amounting to about $3,027 annually.
Car insurance for 17-year-old drivers is typically more expensive because younger drivers are statistically more likely to get into accidents. Their lack of driving experience means insurance companies take on more risk insuring them, resulting in higher premiums.
