Zig-zag lines on the road can be white or yellow and indicate that parking in that area is prohibited. Yellow zig-zag lines are typically found outside schools, police stations and hospital.

Can you park on zig zag lines?
The simple answer is no; you can’t park on zig-zag lines. Both yellow and white zig-zag lines mean that parking is prohibited; however, they are enforced differently.
Yellow zig-zag lines
Yellow zig-zag lines need to have a sign in place to be legally enforceable. The local council enforces yellow zig-zag lines any fine received is a civil matter rather than a criminal one.
White zig-zag lines
White zig-zag lines are enforced 24 hours a day, seven days a week and can be enforced either by the council or by the police. White zig-zags do not need a sign for enforcement, and parking on them at any time is prohibited.
