There are a few ways the center line markings can be used to indicate what rules are relevant when it comes to turning and overtaking. Some quieter, less used roads don't have a line at all, more frequented roads have a dotted or broken center line.

In this article we will be looking at the difference between a Single Solid White Line and Double Solid White Lines. Do you know the difference?

Single Solid White Line

Single Solid CloseTurning Right

The top image on the right shows a Single Solid White line down the center of the road.

Both of these cars ARE permitted to turn right as you are allowed to cross a Single Solid White Line if you are entering or leaving the road. Turning into another road is counted.

Overtaking

You are not permitted to overtake another vehicle where you must cross a Single Solid White Line to do so unless:

  • You need to cross the line to avoid a hazard or obstruction.
  • You are obeying a traffic control device.
  • You are overtaking a bicycle.

But then ONLY if it is SAFE to do so.
