In Michigan, 18-year-old drivers pay an average of $204 per month for liability-only car insurance and $353 for full coverage.
An 18-year-old in Michigan can typically buy their own car insurance policy without permission from their parents, but staying on a parent’s policy may cost less, depending on the insurer and household.
At 18, Michigan teens age out of the graduated driver licensing program. Their new licensing status may earn them slightly lower premiums.
Michigan car insurance for 18-year-olds costs an average of $204 per month for liability-only coverage and $353 for full coverage.
A recent speeding ticket, at-fault accident, or operating while intoxicated (OWI) conviction can push a teen driver’s rates even higher. But having good grades, completing a defensive driving course, and maintaining a clean driving record may help make coverage more affordable.
The average cost of full-coverage car insurance in Michigan for 18-year-old drivers is much higher than the cost of liability insurance, at $353 and $204 per month, respectively. At $149 more per month, that’s a 73% increase. That said, cheaper coverage isn’t automatically the best choice for teen drivers.
Liability coverage costs less, but it won’t pay to repair or replace your teen’s car after an at-fault accident. Full coverage adds more protection and often makes sense for financed, leased, or newer vehicles.
If your teen drives an older car with a low value, liability-only coverage may be enough. Still, families should consider buying more than Michigan’s minimum liability limits, as one serious crash can quickly exceed state-required coverage amounts.
Average liability quotes start at $68/mo.
Michigan doesn’t allow insurance companies to use gender when calculating car insurance rates.[1] That said, male teens in Michigan likely pay higher premiums due to their higher accident rates. In 2023, male drivers were in 71% of fatal crashes involving 16- to 20-year-olds, while female drivers only accounted for the remaining 29%.[2]
Below, you can compare average insurance costs for 18-year-olds in Michigan by gender and coverage level.
Gender | Michigan Average Liability-Only Cost | Michigan Average Full-Coverage Cost |
|---|---|---|
| Male | $212 | $367 |
| Female | $196 | $339 |
USAA, Auto-Owners, and Chubb offer the cheapest car insurance for 18-year-old drivers in Michigan, according to Insurify data. But the cheapest company won’t always be the best fit for your family. You may want to compare coverage limits, deductible options, customer service, and available discounts before choosing a policy.
The table below shows average monthly rates from affordable car insurance companies for 18-year-old drivers in Michigan with their own policies.
Insurance Company | Average Monthly Quote: Full Coverage | Average Monthly Quote: Liability Only |
|---|---|---|
| USAA | $205 | $117 |
| Auto-Owners | $225 | $128 |
| Chubb | $249 | $143 |
| Progressive | $268 | $184 |
| National General | $440 | $200 |
| Liberty Mutual | $373 | $206 |
| Safeco | $367 | $211 |
| Bristol West | $452 | $225 |
| Insurify Car | N/A | $247 |
| Nationwide | $436 | $250 |
| Direct Auto | $531 | $254 |
| State Farm | $441 | $254 |
| GEICO | $418 | $279 |
| Travelers | $552 | $315 |
Keep in mind that a clean driving record can make a big difference for 18-year-olds because some teens have already spent a few years behind the wheel. A driver with no tickets or claims may qualify for better rates than a teen with a recent violation.
Families may also see different prices based on whether the teen drives a family sedan, takes a car to college, or needs their own policy.
Staying on a parent’s car insurance policy is usually cheaper for an 18-year-old driver in Michigan than buying a stand-alone policy.
A shared policy can give families access to multi-car discounts, bundling discounts, and higher coverage limits at a lower overall cost. Adding an 18-year-old to a two-parent policy increases its average monthly cost by $222. But that increase still costs less than an 18-year-old’s own policy, which averages $292 per month.
Unlike newly licensed 16-year-old drivers, 18-year-olds can generally get their own policy without parental approval. Teen drivers who live independently, own their own car, or no longer qualify as a household driver on their parent’s policy may need to consider applying for separate coverage.
Below, you can see the best policy options for 18-year-old drivers in a few different living situations:
Situation | Policy Options | Cheapest Option | Average Monthly Cost |
|---|---|---|---|
| 18-year-old driver who lives at home | Stay on parent’s policy or get your own policy | Stay on parent’s policy | $471 |
| 18-year-old driver lives independently | Get your own policy | Get your own policy | $292 |
| 18-year-old away at college | Stay on parent’s policy or get your own policy | Stay on parent’s policy (if you don’t have a car in your name) | $471 |
Car insurance is expensive for 18-year-olds in Michigan because teens have less experience behind the wheel and higher accident rates than older drivers. Traffic deaths among people ages 13 to 19 increased by 17% in 2024, according to Michigan crash data.[3]
Rates usually start to ease up in a driver’s early 20s — especially when they avoid tickets, accidents, and coverage lapses.
Age matters when insurers calculate premiums, but insurance companies look at more than a driver’s birth date when setting rates.
For 18-year-old drivers in Michigan, the following details can also affect the cost of car insurance:
Driving record
Driving experience
Vehicle type
Coverage level
Deductible amount
Available discounts
Location

In Michigan, 18-year-olds can follow the adult licensing process if they don’t already have a full license.
New adult drivers must pass the knowledge and vision exams, get a temporary instruction permit, practice driving with a licensed adult for at least 30 days, and pass the driving skills test.[4] Getting an unrestricted license won’t automatically lower car insurance rates, but a clean driving record and more driving experience can help reduce premiums over time.
Michigan’s minimum auto insurance requirements apply to drivers of all ages, including 18-year-old drivers. State minimums may satisfy the law, but many families choose higher liability limits for teen drivers because one serious crash can exceed basic coverage amounts.
See the state’s minimum insurance requirements below:
Required Coverage | Michigan Minimum |
|---|---|
| Personal injury protection (PIP) | $250,000 to unlimited, $50,000 for drivers who qualify for Medicaid, or the option to opt out for drivers enrolled in Medicare Parts A and B |
| Property protection insurance | Up to $1 million |
| Bodily injury liability | $50,000 per person / $100,000 per accident |
| Property damage liability | $10,000 for out-of-state property damage |
Car insurance for 18-year-olds can be expensive. But Michigan families may be able to lower insurance costs by shopping around, asking about discounts, and making smart choices about their vehicle and coverage.
Here are a few ways 18-year-olds can save on coverage:
Ask about good student discounts. Many insurance companies offer good student discounts to teens who earn good grades. Ask your insurer what GPA or documentation it requires to qualify for savings opportunities.
Take a defensive driving course. A defensive driving course may help an 18-year-old qualify for savings and build safer driving habits at the same time. Check with your insurer before you enroll, though, since companies set their own rules regarding eligible courses.
Choose a higher deductible. A higher deductible can lower the cost of full coverage. Just make sure your family can afford the higher out-of-pocket cost after an accident if necessary.
Choose the right car. Safe, moderately priced cars usually cost less to insure than sports cars, luxury vehicles, and new cars. Compare car insurance rates before buying a vehicle for your teen to avoid expensive surprises later.
Bundle policies or join your parent’s insurance. Bundling auto insurance with homeowners or renters insurance may lower your overall coverage costs. It can also cost less to join your parent’s insurance policy instead of buying stand-alone coverage — especially if you’re a teen who lives at home.
Michigan’s no-fault insurance rules and higher costs for teen drivers can make shopping for coverage feel confusing. These quick answers can help young drivers and parents compare options with more confidence.
USAA has the cheapest average rates for 18-year-old drivers in Michigan, but it only serves eligible military members, veterans, and their families. Auto-Owners and Chubb offer the next-lowest averages, according to Insurify data.
Insurance companies charge 18-year-olds more because teens have less driving experience than older drivers. Michigan’s no-fault insurance requirements and higher teen crash risk can also affect rates.
An 18-year-old in Michigan can generally buy their own car insurance policy because Michigan considers people adults at 18 for most purposes. But joining your parent’s policy will likely cost your family less overall.
In many cases, yes. Adding an 18-year-old to an existing two-parent policy often costs less than buying a separate policy — especially if the teen still lives at home.
Insurance companies may consider driving record, driving experience, vehicle type, coverage level, deductible, location, and discounts. Tickets and accidents can increase premiums, and full coverage always costs more than liability-only insurance.
Insurify data scientists analyzed more than 250 million quotes served to car insurance applicants in Insurify’s proprietary database to calculate the premium averages displayed on this page. These premiums are real quotes that come directly from Insurify’s 500+ partner insurance companies in all 50 states and Washington, D.C.

Unless otherwise specified, quoted rates reflect the average cost for drivers between 20 and 70 years old with a clean driving record and average or better credit (a credit score of 600 or higher).
Liability-only premium averages correspond to policies with the following coverage limits:
