Car Insurance Terms to Know When Your Teen Drives

Teens are the costliest drivers to insure, and the policy paperwork comes with its own language. Here is what the terms mean and what to ask your agent.

What to remember

1. Insurance agents in California report that adding a 16-year-old male driver typically raises a family premium by 50 to 120 percent, and a 16-year-old female by 30 to 70 percent.
2. A teen with a learner’s permit can usually stay on your existing policy at no extra cost, but teens must have insurance in almost every state once licensed.
3. Raising a deductible from $200 to $500 can cut collision and comprehensive costs by 15 to 30 percent, and a $1,000 deductible can save 40 percent or more.
4. Excluding a licensed teen from your policy means they have no coverage if they drive, which can leave your family responsible for crash damages.
5. Get at least three quotes and ask about good student, driver training, multi-car, and bundling discounts before you sign or renew.

Adding a teen driver to your auto policy is one of the bigger cost changes a family budget can take, and it comes with a vocabulary all its own. Insurers use words like liability, surcharge, and primary driver in specific ways, and misunderstanding one of them can leave your teen underinsured. This glossary explains the terms you will meet, why they matter more with a teenager behind the wheel, and what to ask your agent before you sign or renew.

Why Teen Drivers Change Your Insurance Picture

Teens are the most expensive drivers to insure for a plain reason: insurers expect to pay more claims when an inexperienced driver is on the policy. The size of the jump varies by insurer, state, and vehicle, but the pattern is consistent. Insurance agents in California, for example, report that adding a 16-year-old male driver typically raises a family’s premium by 50 to 120 percent, and adding a 16-year-old female by 30 to 70 percent. A policy that cost $2,400 a year could run $3,800 to $4,800 after a teen is added.

There is some good news built into the numbers. The surcharge usually drops each year your teen keeps a clean record, and it falls significantly by age 25. Waiting to get licensed helps too, since premiums for 19-year-olds are often up to 8 percent lower than those for 16-year-olds.

The permit phase also costs less than you might expect. Most insurers will add a teen with a learner’s permit to an existing policy at no extra charge, because permitted drivers must be supervised by a licensed adult, typically over 21. The real increase comes once your teen passes the driving test and becomes a licensed driver, which is when teens must be insured in almost every state.

The Coverage Types on Every Policy

• Liability coverage. The part of the policy that pays for injuries and property damage your teen causes to other people. It does not pay to repair the car your teen was driving.
• Bodily injury and property damage limits. Liability coverage is usually split into separate maximums, one for injuries to people and one for damage to property. The limits appear as numbers on your policy’s declarations page.
• Collision coverage. Pays to repair or replace your own car after a crash with another vehicle or object, no matter who was at fault.
• Comprehensive coverage. Pays for damage to your car from things other than crashes, such as theft, fire, or storm damage.
• Coverage limit. The most the insurer will pay on a claim. Anything above the limit comes out of your own pocket, which is why very low limits are a poor fit for a household with a new driver.
• Standalone policy. Insurance bought only for your teen rather than adding them to yours. It is usually more expensive, because a teen on their own policy gets none of the benefit of your driving record and your history with the insurer.

Deductibles, Premiums and Costs

• Premium. The amount you pay for coverage, whether monthly, every six months, or yearly. Premiums are based in part on the car’s price, the cost to repair it, its overall safety record, and how likely it is to be stolen.
• Deductible. What you pay out of pocket before the policy pays on a claim. Raising a deductible from $200 to $500 can cut the cost of collision and comprehensive coverage by 15 to 30 percent, and moving to a $1,000 deductible can save 40 percent or more. Before you raise it, make sure you have enough set aside to pay it after a crash.
• Surcharge. The extra amount added to a premium because the insurer considers a driver higher risk. The teen surcharge typically shrinks each year your teen ages and stays ticket-free and accident-free.

Terms That Come Up With Teen Drivers

• Listed driver. A household member formally added to your policy. Once your teen has a license, not just a permit, they generally need to be listed on your policy or covered another way. In California, drivers are required to list all licensed household members on the policy or exclude them explicitly.
• Excluded driver. A household member named on the policy as having no coverage at all. Excluding a teen leaves them with no insurance if they drive your car, which creates a serious gap if they cause a crash.
• Primary driver. The person who drives a particular vehicle most of the time. Assigning your teen as the primary driver of a sports car or a late-model vehicle with high repair costs pushes the premium up sharply.
• Secondary or occasional driver. A driver who uses the car less often. Adding your teen as a secondary driver on a family vehicle, instead of a primary driver on their own car, usually keeps the premium lower and avoids paying to insure an extra car altogether.
• Graduated driver licensing (GDL). State laws that phase in driving privileges for new teen drivers. GDL rules commonly restrict night driving and the number of teen passengers allowed in the car, targeting the conditions where teen crashes are most likely. Passenger limits affect the whole family carpool, too; if younger siblings ride along, our guide to choosing the right car seat for each stage covers how they should be buckled at every age.
• Permit coverage. The way insurers treat a teen who is still driving on a learner’s permit. Tell your agent when your teen gets a permit so it is noted on file, even though most insurers do not charge extra until the license arrives.

Safety alert: Leaving a licensed teen off the policy on purpose, called exclusion, means they have no coverage when they drive. If they cause a crash, your family could be personally responsible for the damages.

Discounts and Savings Terms

• Good student discount. A rate break for students with strong grades, usually a B average or higher. Insurers typically want proof, so keep the report card handy when you call.
• Driver training discount. A discount some insurers offer to teens who complete an approved driver’s education or safety course. Ask which programs qualify before you pay for a class.
• Multi-car discount. A price break for insuring more than one vehicle on the same policy. These discounts can disappear when vehicles are registered at different addresses, which is worth knowing in cases of divorce or shared custody.
• Bundling. Buying more than one type of policy, such as auto and homeowners, from the same insurer to lower the combined price.
• Teen driver discount. A discount some insurers give simply for adding a young driver, often after the family has been with the company for a set period. It never hurts to ask.

Questions to Ask Before You Sign or Renew

Getting a fair deal on insurance follows the same habits as any other purchase your teen talks you into. Verify the details, compare more than one option, and get things in writing, whether the purchase is a policy or a used phone. Our checklist for a teen’s first used phone covers the research routine that transfers well here.

Before you sign or renew, ask your agent:

• How much will adding my teen cost while they hold a permit, and after they get a license?
• Should my teen be a primary driver or a secondary driver, and on which vehicle?
• Which discounts apply to us: good student, driver training, multi-car, bundling, safe driving?
• Does collision and comprehensive coverage still make sense on our oldest car? If the car is worth less than 10 times the premium for that coverage, keeping it may not be cost effective.
• What happens if my teen owns a car? A vehicle registered in your teen’s name generally needs its own policy, while keeping the registration in your name lets you add them as a listed driver on yours.
• If we share custody after a divorce, will my teen be listed on the policies in both households?
• What rate decrease can we expect as our teen builds a clean record?

Finally, shop around. Prices differ from company to company, so get at least three quotes before you commit, and check whether your state insurance department publishes price comparisons and consumer complaint information. Coverage needs shift as your family changes, so an annual review before renewal is a good habit. Timing matters for the rest of the teen budget too, and our guide to buying school gear for less all year long shows how planning purchases around the calendar saves money.

Parents also ask

Do I have to add my teen to my policy once they get a license?

In almost every state, a teen driver must have car insurance, and most insurers cover permitted drivers under your existing policy without a charge. The requirements change once your teen passes the driving test and becomes a licensed driver.

Is it cheaper to add my teen to my policy or buy a separate one?

Adding your teen to your existing policy is usually more affordable. A standalone policy costs more because your teen gets none of the benefit of your driving history and rate.

How can we lower the cost of insuring our teen driver?

Raise your deductible only if you have savings to cover it, list your teen as a secondary driver on a sensible family car, and ask about good student and driver training discounts. Prices vary widely by company, so get at least three quotes.

What happens if we share custody of our teen after a divorce?

Expect your teen to be listed on the auto policies in both households, which can cost more. Multi-car discounts often no longer apply once vehicles are registered at different addresses.
