What does a blue solid line parking space indicate?

[McJames]

Blue parking spaces indicate free motor vehicle or non-motor vehicle parking spaces, representing free parking markings. If the blue marking is a dashed line, it only allows limited-time free parking; a solid blue line indicates long-term free parking. Below is relevant information: Parking space markings: There are three types of parking space markings, namely blue, white, and yellow. Blue represents free parking spaces, white represents paid parking spaces (some of which may be free at night), and yellow represents special vehicle (such as fire trucks) parking spaces. Yellow-marked parking spaces usually allow temporary parking but absolutely prohibit long-term parking. Notes: It is important to note that even if the marking is a blue solid line, it is best not to exceed one hour of parking, otherwise a ticket may be issued. For limited-time free blue parking spaces, there will be signs next to the space indicating the free parking period, which is usually written on the sign. The free parking period is not uniformly regulated and depends on the specific circumstances of the location.
