trafficable

Open to vehicles

Trafficable describes terrain, roads, or routes that can be traveled or passed through.

The word appears most often in military and engineering contexts: The muddy roads were barely trafficable.

A trafficable surface supports vehicle movement; an untrafficable one doesn't.
