 /**
- * Whether to draw unpaved roads regardless of the town zone.
- * By default, OpenTTD always draws roads as unpaved if they are on a desert
- * tile or above the snowline. Newgrf files, however, can set a bit that allows
- * paved roads to be built on desert tiles as they would be on grassy tiles.
+ * Should the road be drawn as a unpaved snow/desert road?
+ * By default, roads are always drawn as unpaved if they are on desert or
+ * above the snow line, but NewGRFs can override this for desert.
  *
  * @param tile The tile the road is on
  * @param roadside What sort of road this is
- * @return True if the road should be drawn unpaved regardless of the roadside.
+ * @return True if snow/desert road sprites should be used.
