When is it illegal to pass another vehicle? Do not pass when:
• oncoming vehicles are too close. If you have any doubts about safely completing the pass, do not attempt to pass
• a solid yellow line is on your side of the centre line
• a sign indicates a no passing zone
• you are in a school or playground zone during school or playground zone times
• another vehicle is stopped to allow a pedestrian to cross at a marked or unmarked crosswalk
• a school bus has flashing red lights and the stop arm extended indicating the school bus has stopped. (It is not the safest choice to pass a school bus that has flashing amber lights, indicating that it is reducing speed, because it may be stopping to allow passengers on and off the school bus. If you do proceed, do it with caution.)Text extracted from the PDF for reference and may contain layout artefacts. The official PDF is authoritative.
