How to use these rules

  1. Check the ceiling before you compare offers

    If a quoted APR looks extreme, compare it against the Washington cap above — and note that a specific statutory exemption can apply to a particular product.

  2. Verify the lender is licensed

    Use the regulator named in the table to confirm the lender or sales-finance company may legally serve borrowers in the state.

  3. Know what is secured against your car

    A vehicle title loan is secured by the car itself. If the state permits it, understand the repossession terms before you sign anything.

  4. Budget for tax and fees separately

    Sales tax and title fees are financed along with the car, so they raise the amount you borrow — and therefore the interest you pay on them.
