This is the most up to date list (as of October 2016) of counties that have opened some level of county/local roads to OHV usage in Colorado.
Following text and list supplied by Stay The Trail Colorado.
Rules regulating the use of off-highway vehicles on public roadways often vary from one city or county to the next. Requirements regarding age of operation, insurance, OHV registration/permit, vehicle types, required equipment and other rules can change as you travel across boundaries between different jurisdictions and local, state, or federal lands. Please check with the local city, county, or land management office for specific rules regulating the use of off-highway vehicles in that area. Local governments often designate OHV routes with signs and/or provide OHV route maps to the public.
Riders should also consider that many off-highway vehicles will perform differently on paved or improved surfaces. Extra care should be taken when operating OHVs on public roads. Ride safe and be courteous when encountering vehicle traffic, bicyclists, and other road users. Remember that OHVs can be louder than most on road vehicles. Colorado Law limits sound emissions of all new OHVs to 96 decibels. Please be mindful of area residents and businesses. This list shows cities/counties that have opened roads to OHVs for transportation/recreation. OHVs used for agricultural purposes are still allowed on public roads and may have access to routes in jurisdictions other than those listed here.
