That is true if the terrain is agreeable. Often it is steep and a
very loose rocky surface so 4wd is necessary. Even if it isn't very
steep, since it is not maintained very often, if at all, erosion
creates hazards in the road also requiring 4wd or at least a very
high clearance vehicle. <br>

<div dir="auto">I would think that an unimproved track across
naturally solid rock or naturally well-compacted gravel would
not be tracktype=grade5 - while it might be bumpy, it’s
probably passable by any vehicke with sufficient clearance and
tire size, even when wet, unlike a track of unimproved clay,
silt or loam which requires 4wd or is simply impassable when
it rains? But I’m not an expert on 4wd.</div>
