Generic Codes
Most manufacturers have specific codes assigned to them; however, generic codes are to be used in some instances. Ensure that if a generic code is used, whether for make, model, etc. that a more specific code is not available. If a specific code is available the entry should be updated to reflect this. The year of manufacture can make a difference in the code to be used; e.g., there are three or four different codes assigned to Jeep depending on the model year. All Terrain Vehicles must be entered using the related motorcycle make code. If the manufacturer of the ATV does not manufacture motorcycles and no Make code is assigned it must be entered with the generic code of "ATV". You must then specify the manufacturer of the vehicle in the Remarks field.
