There are a few ways the centre 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 centre 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
Turning Right
The first image shows a Single Solid White line down the centre 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.
Double Solid White Lines
Turning Right
The second image shows a Double Solid White Line down the centre of the road.
Neither of these cars are permitted to make the Right turn they are indicating as you are not permitted to turn over Double white lines unless:
- There is a break in the lines which you can cross through.
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.
