Car insurance for teen drivers is expensive, but there are ways of saving money on a full coverage policy.

Must an 18-year-old have complete coverage?

There isn’t a regulation for underage drivers for maximum compensation. Getting just liability insurance won’t protect your car. We recommend the following conditions when choosing a full coverage policy:

  • Ensure you have comprehensive coverage to protect against storms, hail, arson, damage to your vehicle, and repairs due to theft.
  • Ensure that you have collision coverage, to protect from damage to your vehicle regardless of fault.

When a teen is driving, it’s best to have as much coverage as possible, even when they practice safe driving.

Which insurance is best for young drivers?

One aspect of auto insurance is liability coverage. This covers losses that a teen causes in an accident to individuals. States provide the minimum coverage for liabilities. That’s usually not enough auto insurance. Property damage liability, and hospital visits due to bodily injury add up quickly. You don’t want to be responsible for out-of-pocket costs.

Comprehensive coverage, and collision are important if you’re financing your car. If you want to lower your premium, it’s best to choose a higher deductible.

What Affects The Cost Of Car Insurance?

Many different factors affect how auto insurance companies determine your car insurance rate. When companies offer you a quote, things like age, gender, location, and even your credit score come into play.

Age of the driver

Younger drivers fall into a specific age group, which causes higher car insurance premiums. The better driver you’re, the better car insurance rates you have. Age comes into play because auto insurance companies see 18-year-olds as inexperienced drivers, and more likely to get into an accident. The average auto insurance for teen drivers is more than for older drivers.

Gender of the driver

Being a girl saves you from paying higher premiums, and deductibles. On average, an 18-year-old male pays more for car insurance than a female. That’s because statistically, women report fewer accidents, and have a lower number of DUIs than 18-year-old males. Some states have outlawed using gender as a factor in quoting car insurance, but not all of them.


Car insurance companies consider everything, including location, to give you the best car insurance quotes. Different cities have different rates, so it’s based on your zip code. They determine how much theft and vandalism there are, and the rate of accidents in your area.

Credit score

Your credit score is a factor in determining the average rates for car insurance. Insurers believe that drivers with excellent credit scores are more dependable drivers.
