Anyone doing so would have to ignore these sections of the MV Act...at their peril.
Passing on right
158 (1) The driver of a vehicle must not cause or permit the vehicle to overtake and pass on the right of another vehicle, except
(a) when the vehicle overtaken is making a left turn or its driver has signalled his or her intention to make a left turn,
(b) when on a laned roadway there is one or more than one unobstructed lane on the side of the roadway on which the driver is permitted to drive, or
(c) on a one way street or a highway on which traffic is restricted to one direction of movement, where the roadway is free from obstructions and is of sufficient width for 2 or more lanes of moving vehicles.
(2) Despite subsection (1), a driver of a vehicle must not cause the vehicle to overtake and pass another vehicle on the right
