It's country specific. In Australia one-lane roads are the norm in rural areas and are tagged tertiary if they go somewhere and 'unlassified' if the don't. We use tracks for gravel fire trails, forest trails, National park trails, 4WD trails etc. Basically something you think twice about taking a 2wd on after rain.
