The lane is where you drive. A verge is the grass edge of a road. A pathway is where pedestrians walk. The road edge might have a kerb made from raised concrete or stone. Roads are marked with lines. Lanes are formed either between kerbs, verges, painted lines, a kerb and painted line or a verge and painted line.
