Insuring a teen driver

Adding a teenager to a car insurance policy is one of the biggest single changes a household's premium ever sees. It isn't personal; new drivers, whatever their age, crash far more often per mile than experienced drivers, and the first months of solo driving are the riskiest of all. This guide covers what changes, the choices that soften the cost, the coverage decisions that matter more with a young driver in the house, and the habits that keep a teen's record clean for years.

Why the premium rises

Insurers price inexperience. A newly licensed driver has no track record, and the statistics for that group are poor, so the driver factor is high. The increase depends on which car the teen is assigned to, whether they're the primary or occasional driver of it, the coverages on that car, and the state. Boys' rates are often higher than girls' where state law allows gender to be used. The good news is that the driver factor falls steadily with each claim-free, ticket-free year.

Add them to your policy or buy a separate one?

In almost every case, adding a teen to a parent's policy costs less than a separate policy, because they benefit from the parents' discounts, driving history and multi-car pricing. It also keeps the household's liability coverage in one place. A separate policy is mainly worth considering if the teen owns a car titled in their own name and lives elsewhere, or if their record has become bad enough to drag the family premium up. If your teen is a licensed driver living in your household, most insurers expect them to be listed on the policy, whether or not they own a car.

The learner's permit stage

Many insurers cover a permit holder under a parent's policy without an added charge until the teen is fully licensed, but they want to be told. Call your insurer when the permit is issued and ask how they handle it, and again when the license is issued, because that's usually when the rate changes. Don't wait for the insurer to find out; an unlisted driver can complicate a claim.

The car matters

Which car a teen mainly drives changes the premium and, more importantly, their safety. A few principles hold across insurers:

• Assign the teen to the least expensive car to insure, if you have more than one, and tell the insurer that assignment honestly.
• Prefer a mid-size car with strong crash test ratings, electronic stability control and a full set of airbags. Very small cars protect occupants less; very large or high-performance vehicles are harder for new drivers to control.
• Avoid cars that invite speed. Sports cars and high-horsepower models cost more to insure for anyone and far more for a teen.
• An older car isn't automatically cheaper to insure if it lacks modern safety equipment, and it may not be safer.

The Insurance Institute for Highway Safety publishes recommendations for young drivers that are a useful starting point for choosing a car.

Discounts built for young drivers

• Good student. Full-time students under a set age with a B average or better, typically. Keep a transcript ready at each renewal.
• Driver training. Completing an approved driver education or defensive driving course.
• Student away at school. If the student attends school a set distance from home without a car, they're rated as an occasional driver.
• Telematics. Usage-based programs reward smooth, daytime, low-mileage driving and give parents visibility into how the teen is driving. Read the terms: some programs can raise a rate for poor scores.
• Multi-car and bundling. The household discounts continue to apply when a teen is added.

Coverage decisions that matter more now

A teen driver raises the chance that someone in your household causes a serious accident. Two decisions deserve a fresh look:

• Liability limits. If your limits are near the state minimum, consider raising them. The cost of a serious injury claim can exceed minimum limits quickly, and the parents' assets are exposed when a teen driver on the policy is at fault.
• Umbrella coverage. A personal umbrella policy adds liability protection above your auto and home limits. Many families add one when a teen starts driving. Insurers usually require the underlying auto policy to carry certain minimum limits first.

Collision and comprehensive on the teen's car are a judgment call based on its value, as with any car; our deductible guide walks through it.

Excluding a driver: think carefully

Some policies allow you to exclude a specific household member from coverage, which removes the rate increase. The trade-off is severe: if the excluded person drives the car for any reason and crashes, there is no coverage at all, and the parents may be personally liable. Some states don't allow driver exclusions, and some insurers won't write them. It's rarely the right answer for a teen who has access to the car keys.

Rules at home, and the value of a clean record

Every state has a graduated licensing system that limits new drivers' night driving and passengers for a period. Those limits exist because both factors sharply raise crash risk for teens, and enforcing them at home, along with a strict no-phone rule, does more for safety than any insurance feature. It also protects the premium: a ticket or an at-fault accident on a teen's record raises rates for several years and can cost far more than the original increase from adding them. A written agreement covering when the car can be used, passengers, phones and consequences is a common and effective tool.
