What are 'sandwich board signs' used for in parking management?

Sandwich board signs are commonly used in parking management primarily to provide information about parking restrictions or events. These signs are portable and often placed on sidewalks or near parking areas to effectively communicate important details to drivers. For instance, they might inform motorists about temporary changes in parking rules, special events that could affect parking availability, or other relevant notifications that help manage parking usage in a specific area.

The versatility of sandwich board signs allows for dynamic updates, making them an effective tool for managing compliance with parking regulations and responding to special circumstances. This feature enables authorities to rapidly convey changing information, which can enhance the overall flow and organization of parking in dynamic environments such as urban centers or event venues.
