有時候，從街道景照片看往人行道的視線完全被阻擋了，在這種情況下，您可以標記「看不見人行道」。這種情況應該不常見到，因此請只在當人行道、路緣斜坡或其他可及性問題，受阻礙物體（例如路邊停車）遮蔽而無法從任何角度觀察到時，才標記為「看不見人行道」。

Another rare case when you should use the "Can't See the Sidewalk" label is when a long stretch of sidewalk is totally blocked from view by a short wall between the road and sidewalk. Label this using the same technique as for extended missing sidewalks.
