PassNo Overtaking Lines
Where: Down the centre of a two-way road wherever sight distance is too short to overtake safely — approaching blind rises, bends, bridges, intersections and pedestrian crossings.
Purpose: To prohibit overtaking and crossing. A double solid line binds traffic in both directions: neither side may cross it. Where only one of the pair is solid and the other broken, the rule applies to the side with the solid line nearer to it.
Action Required by Driver: Stay in your lane. You may not cross or straddle these lines to overtake, and you may not cross them to turn across oncoming traffic except where a break in the marking allows it. If you are already committed to an overtake when the line begins, complete it and return to your lane as quickly as it is safe to do so.
A regulatory marking, not a suggestion
Road markings fall into the same legal class as signs. Disregarding a regulatory marking is an offence in exactly the way that disregarding a stop sign is, and the absence of a sign on a pole changes nothing.
