There are 3 types of “road;” Pikes, Roads, and Trails.
Units utilize road movement by moving along the road, from one hex to another by way of a hexside crossed by that road. Units may use the rate of that road type so long as the unit is not in, nor enters a ZOI. A unit may combine different road types and non-road movement and it may enter a ZOI during its move, but it cannot use road movement rates in any hex that is within a ZOI. A unit that used any road movement rate at all may not enter a ZOC.
Roads may negate the effects of other terrain in the hex, even if not using the road movement rate. This is not considered using road movement in the case of entering a ZOC or cavalry charges. See the TEC for specific cases.
