A 21-year-old driver typically pays around $365 annually for liability-only car insurance and $1,953 for full coverage under a family policy.
The main factors influencing car insurance costs for 21-year-olds include driving experience, the type of vehicle driven and the driver's location. Insurers generally view younger drivers as higher risk on the road, resulting in higher premiums.
While 21-year-olds can obtain their own insurance, many choose to stay on their families' policies to save substantially on costs.
