How much is car insurance for an 18 year old?

Car insurance for a 18-year-old driver is nearly $5,190, on average, for a year of full coverage on their own policy. That’s more than $3,430 over the national average ($1,758) for drivers age 30. Newly licensed drivers are expensive to insure. They are inexperienced, naturally, and have a high rate of accidents. Auto insurance companies view that as risky. So, they charge new, teen drivers much higher rates. Here we will provide average car insurance rates for 18-year-old males and females by state, as well as by coverage level, and show how a parent's rates are affected when you add a teen to your policy. You'll also get expert advice on how much coverage to buy and discounts for young drivers.

How much is car insurance a month for an 18-year-old?

On average, teen drivers age 18 will pay about $430 a month for car insurance for a full coverage policy.  If you buy just enough insurance to drive legally in your state, it’s about $160 a month. Below are car insurance costs per month for common coverage levels:

• State minimum policy: $158
• Full coverage, 100/300/100 liability with comprehensive and collision: $432

Concord, USAA, Liberty Mutual, Geico, Erie, Travelers, State Farm, Progressive and Nationwide are the national carriers that have the cheapest car insurance for 18-year-olds, among companies surveyed by CarInsurance.com.

How much does it cost to add an 18-year-old to car insurance?

Though adding a teen to a parent policy is cheaper than the teen having his or her own separate policy, the cost of adding a teen driver can still be pricey. Below are the average annual costs to add an 18-year-old man or woman to your coverage.

Every situation is different, but to get an idea of what you can expect to pay, CarInsurance.com compared rates in 10 ZIP codes in each state. The family profile we used owned a 2018 Honda Accord driven by a 45-year old man buying full coverage. Then we added an 18-year old teen to the policy. Here's what happened:

• The average household's car insurance bill rose by about 90% to add a teen age 18.
• An 18-year-old male son was more expensive. The average bill rose 101%, compared with 80% for women age 18.

How much you save by adding an 18-year-old to your insurance vs. teen’s own policy

You’ll see in the chart below how much it costs to add a teen driver to a parent policy and how much you save doing so:

When it comes to car insurance for young drivers, most parents take the easier, and far more common, approach of adding a teen to their policy. For one thing, it's likely to be cheaper.

Insurers base premiums on several factors, including the experience and driving record of the policyholder. An 18-year-old won't have that, which means higher rates.

Also, as CarInsurance.com Senior Consumer Analyst Penny Gusner points out, the teen won't be eligible for rate reductions the parent may qualify for, including multi-vehicle, multi-policy and loyalty discounts. Still, adding an 18-year-old driver to your policy means a significant hike in your rates.

Car insurance for 18-year old: State minimum coverage

The cheapest car insurance you can get is a policy that meets just your state’s minimum car insurance requirements. Typically, buying just the state mandated coverage to legally drive means your insurance will pay for others’ injuries and car damage, but not for your own injuries or car repairs. You’ll see in the charts below how much minimum coverage costs, on average, per year in each state, for a teen buying his or her own policy.

Does an 18-year-old have to have full coverage?

There is no law requiring teen drivers to have full coverage. However, if the car being driven is leased or financed, the lender will mandate that you have full coverage, which includes comprehensive and collision insurance.

To drive legally, you only need state required liability insurance, which pays for damage and injuries of others in accidents you cause. It doesn’t cover your own car. However, because teens are inexperienced, and as a demographic have more accidents than experienced drivers, it’s wise to have full coverage on the car your teen drives.

Insurance applies to the car, not the driver. That means the coverage on the car that the teen is driving will apply to accidents and damage caused by the teen.

Gusner recommends a full coverage policy of the following:

• $100,000 for injury liability for one person, to pay for medical bills for those injured in an accident you cause
• $300,000 for all injuries in one accident that’s your fault
• $100,000 for property damage you cause, for instance, to repair a car you hit
• Collision insurance, to pay for damage to your car regardless of fault in an accident
• Comprehensive, to pay for damage to your car from hail, flooding, fire, vandalism, animal strikes, and to replace it if stolen

It really is worth the extra money to be fully protected during the time your teen is driving your car. Otherwise, you can be on the hook to pay out of your own pocket for even minor accidents that can exceed a bare-bones policy. The cost to jump from state minimum to full coverage with an 18-year-old daughter on your policy is about $1,672, but that’s just $139 a month for peace of mind. For an 18-year-old son, the extra cost to buy full coverage with him on your policy instead of state minimum is $1,884, or $157 a month.

The 18-year-old lives with parents and has a clean driving record

Gusner says that teens living at home with no major traffic violations or accidents should definitely be on the parent's policy.

"It's typically less expensive to stay on the parent's policy for as long as possible," she says.

The 18-year-old can actually help lower a parent's premiums by maintaining a good driving record for every year on the policy.

The 18-year-old has a good record but doesn't live with parents

Gusner says it's usually a good idea to get teens a separate insurance policy if they have a car and don't live at home.

They should also have coverage if they don't own a car but drive another vehicle. For instance, a roommate's vehicle.

In that case, she says a good option is a non-owner car insurance policy, which will provide protection and also continual coverage, resulting in lower premiums over time. "Or, if the 18-year-old has a roommate and uses that person's vehicle regularly, he should be added to the owner's car insurance policy," Gusner adds.

The 18-year-old lives with parents but has a bad driving record

Much will depend on the teen's driving record. That includes the number and frequency of moving violations and accidents.

Gusner advises parents and teens to shop around and compare how much it would be to keep the 18-year-old on the family policy versus a separate policy for the teen. "Normally, it's still cheaper for the 18-year-old to be on the parent's policy and take advantage of discounts the parents have that trickle down to the kid, such as multi-car, multi-policy and others," she says.

The 18-year-old has a bad record and doesn't live with parents

Gusner says parents should remove a teen with a poor driving record from the family policy if he or she no longer lives with them. The teen should, instead, get his or her own policy.

"The parent's rates should go down if (the teen) is taken off," she says.

Car insurance discounts for 18-year-old

Rather than skimping on coverage, a better idea is to maximize discounts. Discounts vary by company and state. Here are typical car insurance discounts for teens:

• Good student: A savings up to 15 percent may be available for drivers who maintain a 3.0 or "B" average in the classroom. Gusner says this applies to students in either high school or college.
• Driver education: You may be able to get a 5 percent discount if your teenager completes a driver education course. A state may require the class as a step toward getting a license.
• A driving contract between parents and teen: An insurer may give a discount up to 5 percent to teens who sign a contract with their parents about driving rules, such as limiting hours on the road and the number of passengers.

Shop around for car insurance

Adding a teen to an insurance policy or teens getting their own car insurance is costly. The best way to minimize the pain is to shop around. Compare car insurance quotes from multiple insurance companies. Each insurer uses its own method for calculating what you pay, so prices for the same policy vary.

There is some good news. Car insurance gets cheaper as you age. Average car insurance rates by age show that premiums begin to decrease significantly when drivers turn 26.
