The One-Way sign indicates to drivers that traffic is allowed to travel only in the direction of the arrow, on the road or section of road.

One-Way signs must be placed on the near right
and far left corners of the intersection to face traffic entering or crossing the one-way road. Where the intersection is signalized, signs must be placed as close as practicable to the appropriate traffic control signal faces.

One-Way signs may also be placed parallel to the one-way road directly opposite the exits from driveways, alleys and other public vehicle access places. The One-Way sign must always be used in these situations rather than a turn control sign.
