What must be ensured when placing temporary signs for public safety?

Ensuring visibility and clarity when placing temporary signs for public safety is essential because these signs need to communicate important information quickly and effectively to road users. When a sign is highly visible, it can be easily seen from a distance, allowing drivers and pedestrians to react appropriately. Clarity ensures that the message on the sign is straightforward and unambiguous, reducing the potential for confusion in critical situations, such as construction zones or detours.

Visibility can be achieved through factors such as placement height, reflective materials, and adequate lighting. Clarity involves using plain language and symbols that are universally understood. This combination plays a crucial role in maintaining safety and efficiency on the road during temporary traffic adjustments, which is the primary objective of Traffic Management in construction and maintenance scenarios.

Other factors like artistic design, color coding, and size variations may contribute to aesthetic appeal or specific functional needs, but they do not directly address the primary goal of ensuring that signs are safely and effectively communicating important information to the public.
