Class II ATV, as defined in ORS 801.193 means any motor vehicle that weighs more than a Class I all-terrain vehicle; Is designed for or capable of cross-country travel on or immediately over land, water, sand, snow, ice, marsh, swampland or other natural terrain; and Is actually being operated off a highway or is being operated on a highway for agricultural purposes under ORS 821.191. Most riders refer to a Class II ATV as a Truck or Jeep (SUV), Dune Buggy, Sand Rail, or Side-by-Side UTV vehicles. Side-by-sides are Class II All-Terrain Vehicles because they are either too wide (greater than 50 inches) or too heavy (over 800 pounds) to be classified as Class I All-Terrain Vehicles.
All riders any class ATV under the age of 18 must wear a helmet. Not only is it the law in Oregon, it is also a good idea!
