Terrain tags likely.
Certain terrain types (water, desert, grass, oceans) can have different terrain types which allow/disallow travel on these types. Not only do you consider terrain types which allows vehicles to travel along the terrain, but you also need to consider the terrain types for where vehicles are allowed to dock/disembark. You may have considered the movement terrain tag, but not the landing/docking tag.
