(1) When may I change my vehicle registration from a nonfarm use class to a farm use class?

You may change your vehicle registration from a nonfarm to farm use class when the vehicle is being used solely for farm purposes as defined in RCW 46.16.090.

(2) When is the best time to change my vehicle registration from a nonfarm use class to a farm use class?

The best time to change your vehicle registration from a nonfarm to a farm use class is at the time you are purchasing gross weight. Changing use class from nonfarm to farm results in a forfeiture of gross weight fees paid. You may increase your declared gross weight to make up the difference between the nonfarm and the farm gross weight fees if the increased gross weight does not exceed the maximum legal limit of the vehicle.

(3) What would the gross weight expiration date be when I change my vehicle registration from a nonfarm use class to a farm use class? The expiration date of the gross weight license would remain the same as the current gross weight license.

(4) What will be the start date of the gross weight license when I change my vehicle registration from nonfarm use class to a farm use class? The start date of the gross weight license would remain the same as the current gross weight license.

(5) How many months gross weight must I purchase when I change my vehicle registration from nonfarm to farm?

You will need to purchase the number of months remaining on the current gross weight license. Credit will be given as provided in subsection (6) of this section. You will also be charged for the permit fees as defined in RCW 46.16.135, in addition to all other fees required to license the vehicle.

(6) Will I receive credit for gross weight fees that I have already paid?

You will receive dollar value credit for the number of months and at the rate of the declared gross weight previously purchased for the period between the effective date of the change in use class and the expiration date of the previously issued gross weight license. At the time of application for change of use class from nonfarm to farm, any excess credit accrued as a result of such change may be applied toward the payment of gross weight license fees for the gross weight license months between the nonfarm gross weight license expiration date and the registration expiration date. Credit may not be carried over to the next registration year and any credit still remaining after purchasing gross weight license to the registration expiration date forfeit. You must surrender the current gross weight license in order to receive credit. If the gross weight license is lost, stolen or destroyed, you must sign an affidavit of loss and a statement that the gross weight license has not been transferred to another vehicle. You will not receive credit for the monthly gross weight permit fees as defined in RCW 46.16.135.
