Green Driver State Incentives in South Carolina

South Carolina's green drivers have plenty of opportunities to save time and money with eco-friendly incentives. These perks include auto insurance discounts, state and federal tax incentives, weight exemptions for having idle reduction technology, and more.

Keep in mind these green driver incentives and related vehicle laws might evolve as SC focuses even more energy on the environment. Also periodically consult your local Department of Motor Vehicles (DMV) branch and the Alternative Fuels Data Center for the latest.

SC Auto Insurance Discounts for Eco-Friendly Driving and Green Vehicles

Certain South Carolina auto insurance providers offer insurance discounts for having green driving habits and/or driving a fuel-efficient vehicle. Check with your current provider on green vehicle discounts such as:

  • Hybrid auto discounts.
  • Alternative fuel vehicle (AFV) discounts.
  • Economy car discounts.
  • Low-mileage discounts.
  • Pay as you drive discounts.

Of course, auto insurance discounts vary by provider and circumstances. For example, you might receive a 10% discount on car insurance for owning or leasing a hybrid car, while maintaining low mileage can earn you up to a 30% auto insurance discount.

South Carolina Idle Reduction System Weight Exemption

If your vehicle is equipped with an idle reduction system, South Carolina allows it to exceed the maximum gross vehicle weight and axle weight limit by up to 400 pounds. This weight exemption covers the extra weight added by such idle reduction technology. However, if law enforcement requests proof that this technology is fully functional, and that the added weight can be attributed to your idle reduction system, you must comply.

For complete details on vehicle weights and loads, and the penalties attached to violating such laws, refer to South Carolina Code of Laws 56-5-4160.
