What does a blue parking sign indicate?

A blue parking sign indicates that parking is allowed with a valid parking ticket. This means that drivers are permitted to park their vehicles in the area designated by the blue sign, but they must first obtain and display a valid parking ticket. This can often involve paying a fee, and the ticket must be visible from outside the vehicle.

In many places, the blue sign helps to distinguish between different parking regulation zones, with blue often signaling paid parking areas or areas that require some form of payment or permit. Understanding this is essential for compliance and helps prevent fines associated with improper parking behavior.

The other choices imply different parking regulations that do not align with the meaning of a blue parking sign. For instance, signs that indicate no parking or free parking would use different colors or symbols to convey those rules, helping drivers to understand their parking restrictions clearly.
