What’s the best car insurance for 25-year-old drivers in South Dakota?
By the age of 25, many young adults begin to build their finances and can afford more than liability car insurance, which covers injuries and damage inflicted on others in an accident up to your policy’s limits. However, state-mandated minimum coverage often falls short, particularly as medical costs can add up significantly in case of a severe accident.
As young adults start to have more disposable income, it’s wise to consider adding comprehensive and collision coverage, especially if they’re financing a car. Opting for a higher deductible can reduce your insurance premium, but remember, you’ll need to cover the deductible if you file a claim.
Ultimately, the best car insurance for a 25-year-old driver is the one that fits their specific needs. CarInsurance.com’s Best Insurance Companies survey found that the American Family is the best insurance company for young drivers and teens.
To make an informed choice, consider a company’s National Association of Insurance Commissioners (NAIC) score, which ranks an insurer based on the number of customer complaints it receives, its J.D. Power auto claims satisfaction rating and AM Best data, which evaluates financial stability.
Car insurance discounts for 25-year-olds in South Dakota
Kevin Lynch, an assistant professor of insurance at The American College of Financial Services in Bryn Mawr, Penn., stresses that the three biggest favors any young adult can do for themselves in terms of getting the lowest insurance rates are to stay accident-free, have a clean driving record and maintain a good credit score.
“They’re the essentials of getting affordable insurance,” he says. “After that, you can look at a variety of other things such as affiliated discounts, bundling insurance policies and perhaps an in-car monitoring device.”
Other car insurance discounts that might be available:
- Good driver/safe driver: Up to 30%
- Multi-policy discounts: Up to 13%
- Lower annual mileage/driving less: Up to 9%
- Usage-based discount programs/telematics: Up to 10%
- Paperless discount/autopay: Up to 4%
- Loyalty discount: Up to 11%
- Anti-theft devices: Up to 2%
Beyond discounts, be mindful of the type of car you buy. A practical, safe and reliable car will have a much lower insurance rate than a sports or luxury vehicle.
