Minimum Coverage Requirements in South Carolina
South Carolina requires all drivers to carry minimum liability coverage of $25,000 per person/$50,000 per accident for bodily injury and $25,000 for property damage (25/50/25). Teen drivers in South Carolina progress through a three-stage graduated licensing system: a learner's permit held for at least 180 days (starting at age 15), an intermediate restricted license with passenger and nighttime restrictions, and a full license at age 17. South Carolina law mandates that all insurers offer good student discounts to drivers under 25 who maintain a B average or better, making this one of the few states with a legally required teen driver discount.
How Much Does Car Insurance Cost in South Carolina?
Teen driver insurance costs in South Carolina are driven by crash statistics (16-year-olds have crash rates nearly 4 times higher than adult drivers), the three-stage graduated licensing system that affects risk assessment, and vehicle choice. South Carolina's mandated good student discount and widespread availability of telematics programs from major carriers create more discount opportunities than in most states, though the base rate increase for adding a teen remains substantial.
What Affects Your Rate
- Good student discount (mandated by South Carolina law): reduces premiums 10–25% for students maintaining a B average or 3.0 GPA, available through age 25
- Telematics programs: enrollment in usage-based insurance monitoring programs (offered by most major carriers in South Carolina) can reduce teen driver premiums 15–30% based on safe driving behavior including smooth braking, limited nighttime driving, and no speeding
- Vehicle type: insuring a teen on a used sedan with strong safety ratings costs 30–50% less than adding them to a new SUV or sports car; vehicles with automatic emergency braking and other advanced safety features may qualify for additional discounts
- Defensive driving course completion: South Carolina-approved defensive driving courses can reduce teen driver premiums 5–15% and may also qualify the teen for earlier progression through graduated licensing stages
- Graduated licensing stage: teens holding a learner's permit with supervised driving only see lower rate increases ($80–$150/mo) compared to intermediate license holders who drive independently ($250–$450/mo)
- Add-to-parent vs. standalone policy: keeping a teen on a parent's policy in South Carolina is typically 40–60% cheaper than a standalone policy due to multi-car discounts, loyalty discounts, and shared liability limits, though teens with their own vehicles or living separately may need standalone coverage

Adding Teen to Parent Policy vs. Standalone Coverage
The primary decision parents face: adding a teen to an existing policy is almost always cheaper than a standalone policy for the teen, typically by 40–60%. Multi-car discounts, policy bundling, and shared liability limits all reduce the per-driver cost.
Liability Coverage for Teen Drivers
South Carolina's 25/50/25 minimum is insufficient for most families with teen drivers. A single at-fault accident by an inexperienced driver can result in six-figure liability claims, and parents' assets are exposed if their teen causes serious injury or property damage.
Collision and Comprehensive (Full Coverage)
Full coverage protects the vehicle your teen drives. For vehicles worth less than $3,000–$5,000, some parents opt for liability-only coverage and self-insure collision risk, while parents with financed or newer vehicles maintain full coverage as required by lenders.
Uninsured Motorist Coverage
Protects your family when your teen is hit by an uninsured driver. South Carolina requires insurers to offer this coverage, though you can reject it in writing. Given teen drivers' elevated accident risk and the state's uninsured driver rate, most advisors recommend carrying UM coverage.
Good Student Discount (State-Mandated)
South Carolina is one of the few states that legally requires all insurers to offer good student discounts to drivers under 25 who maintain a B average or 3.0 GPA. This discount applies from the learner's permit stage through age 25, including college students.
Telematics and Usage-Based Insurance
Smartphone apps or plug-in devices monitor driving behavior (braking, acceleration, speed, time of day) and adjust premiums based on safe driving. For teen drivers, telematics programs create an incentive for safe habits and can significantly reduce premiums.
