  • Green Driver State Incentives in Washington

    Washington entices locals to go green with numerous money-saving green driver incentives. These eco-friendly perks include emissions test exemptions for electric vehicles, hybrids, and other fuel-efficient vehicles, state and federal tax incentives, auto insurance discounts, and more.

    These incentives and related green vehicle laws are subject to change. Refer to the content below, your local Washington Department of Licensing branch , and the government's Alternative Fuels Data Center to keep pace with the latest.

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

    You might be eligible for an auto insurance discount if your Washington car insurance company rewards green driving habits and/or driving a fuel-efficient vehicle. Consult your auto insurance provider about potential green vehicle discounts such as:

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

    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.

    If your current Washington auto insurance carrier doesn’t offer such insurance rate discounts, find one that does. Compare auto insurance rates online and save some green for going green.
