Are farm trucks subject to over-dimension permit requirements?
Yes, farm trucks of a certain size, weight, or height must obtain an over-dimension permit and safe routing instructions. Farmers with questions about truck size and weight limits, and highway routing for over-dimension loads, should contact the MCTD Over-Dimension Permit Unit at 503-373-0000 (use phone Option #1). 15. Do farmers have to pay Oregon’s weight-mile (road-use) tax or post a bond to insure payment of taxes and fees? Farmers do not have to pay road-use (weight-mile) taxes and they don’t have to file a surety bond if they use trucks for the farm-related purposes permitted by Oregon law (see Question #4). Farmers have to pay road-use taxes when they use their farm-plated trucks to provide a for-hire transportation service * (hauling things for others for compensation). At what point do operations become subject to weight-mile tax if a farmer hauls for-hire one week and for his farm the next? When did the for-hire hauling actually end and when did the farm-related hauling begin
