If you see single YELLOW straight line by the side, or no line at all that means FREE and you can park there.
But for single YELLOW straight line it’s illegal to park between 7am and 7pm except on Sundays and public holidays!!! It’s is only free after 7pm.
But take note that you cannot park at the side if the centre line is a white unbroken line, and along bends, narrow roads, and near intersections.
Watch this video to see where you CAN or CANNOT park for free!!
