How to save money on car insurance in South Dakota

To save money on your car insurance premiums in South Dakota or anywhere else, follow these tips:

  • Decrease your deductible: Your premiums are partially based on your deductible — the amount of money you pay for repairs or injuries before your insurer starts paying out on a claim. The higher your deductible is, the lower your premiums will likely be. That means increasing your deductible can lower your current insurance premium.
  • Take a driving course: Some insurers offer discounts if you complete a qualifying defensive driver course. To find out if your insurer offers a defensive driving discount, contact your agent.
  • Ask about other discounts: Call, email, or visit your local agent to ask about other insurance discount programs. Most insurers offer several discounts, including good student, multi-policy, multi-vehicle, and accident-free discounts.
  • Do your homework: Before purchasing a policy, shop around and request quotes from several companies to find the best car insurance rates possible.
