A one-way road provides for vehicular traffic travelling in a single direction. It could have one or more lanes and could be in either an urban or rural environment.
The principles for road marking and delineation for one-way roads should be similar to that described for two-lane two-way roads, or multi-lane roads except where otherwise stated in Table 2‑40.

There may be situations where a contra-flow cycle lane could be used to provide for cycling on a route, for example, on one-way streets where a bylaw allows this. This treatment should only be applied in low speed and low-volume environments, and where a suitable transition at each end of the street can be achieved. Treatments at any side streets or driveways should also be considered carefully. For guidance on the provision of contra-flow cycling facilities, refer to contra-flow facilities.
