Minimum Coverage Requirements in Montana
Montana requires minimum liability coverage of 25/50/20: $25,000 per person for bodily injury, $50,000 per incident, and $20,000 for property damage. Teen drivers in Montana move through a graduated driver licensing (GDL) program that begins with a learner license at age 14.5, an intermediate license at 15 (with restrictions on nighttime driving and passengers), and a full license at 16.5 after completing at least 50 hours of supervised driving. Montana law mandates that all insurers offer good student discounts to drivers under 25 who maintain a B average or equivalent, making this one of the most accessible teen driver discounts in the state. Parents adding a teen driver must verify their teen meets the supervised driving requirement before the intermediate license is issued.

Teen driver insurance in Montana is expensive because actuarial data shows drivers under 19 have crash rates three times higher than drivers in their 30s. Adding a teen to a parent's existing policy is almost always cheaper than purchasing a separate policy — typically by 30–50% — because the teen benefits from the parent's multi-car, tenure, and bundling discounts. Montana's state-mandated good student discount, driver training discounts, and telematics programs can reduce the teen driver premium increase by 15–30%, making discount stacking the most effective cost management strategy for parents.
What Affects Your Rate
- Montana law requires all insurers to offer good student discounts to drivers under 25 with a B average or 3.0 GPA, typically reducing premiums by 10–20%.
- Completing an approved driver training or defensive driving course in Montana can reduce teen driver rates by 10–15%, and some insurers extend the discount for multiple years.
- Telematics programs that monitor speed, braking, and nighttime driving are available from most major carriers in Montana and can reduce rates by 15–30% for safe teen drivers.
- The vehicle the teen drives has a significant impact on premiums — a 10-year-old sedan with good safety ratings costs far less to insure than a newer SUV or a vehicle with high theft or repair costs.
- Adding a teen to a multi-car policy with existing bundling and tenure discounts is typically 30–50% cheaper than purchasing a separate standalone policy for the teen.
- Montana's rural driving environment and wildlife exposure increase comprehensive claims, making vehicle choice and coverage decisions particularly important for teen drivers in less populated areas.

Liability Insurance for Teen Drivers
Liability covers injury and property damage the teen causes to others. Montana's 25/50/20 minimums are a legal floor, not a safe limit.
Collision Coverage for Teen Vehicles
Collision pays to repair the teen's vehicle after an at-fault accident. Whether to include it depends entirely on the vehicle's value and the family's ability to absorb replacement cost.
Comprehensive Coverage for Montana Conditions
Comprehensive covers non-collision damage: theft, hail, animal strikes, vandalism, and weather. It's typically less expensive than collision and protects against risks beyond the teen's control.
Uninsured Motorist Protection
UM/UIM coverage protects the teen and their family if injured by a driver with no insurance or insufficient coverage. Montana requires insurers to offer it, though it can be declined in writing.
Good Student Discount (State-Mandated)
Montana law requires all insurers to offer good student discounts to drivers under 25 who maintain a B average or 3.0 GPA. This is not optional — every carrier must make it available.
Telematics and Usage-Based Programs
Telematics programs use a mobile app or plug-in device to monitor driving behaviors like speed, hard braking, and nighttime driving. Safe driving results in premium discounts.
