How to Use Digital Billboards for Public Service Announcements

People usually see a billboard for only a few seconds, so PSA messages should be short, clear and easy to understand at a glance. Use a few strong words, keep the tone consistent, and use strong contrast between text and background. On screens visible to drivers, avoid animation, flashing or rapid changes, and follow local rules on moving content.

Some best practices:

• Font selection: Use clean, sans-serif fonts for easy reading from a distance.
• Colour: Choose colours that suit the message and keep strong contrast for readability.
• Calls to action: Use a simple, memorable, real resource, such as an official helpline number or short web address provided by the responsible authority or organisation. Roadside screens should not ask drivers to text, call or scan while driving.

A quick reference for PSA content:

Placement determines who sees your PSA. Busy roads, city centres and intersections with heavy footfall reach many people. For local messages, community hubs and places where people gather may work better. Match the location to your audience’s routines.

Factors to consider when choosing locations:

• Audience: Choose areas where the people your PSA is meant for actually pass.
• Commuter Behaviour: Morning and evening rush hours bring many viewers, but also busy traffic, so keep messages simple.
• Seasonal Relevance: Festivals and events can bring larger crowds to certain areas.

Because digital billboards can be updated remotely, PSAs can be kept current, for example with weather safety advice, air-quality information or local notices. Emergency warnings and safety instructions should come only from the responsible authorities and be published under an agreed procedure between the authority and the screen operator, with checks to prevent mistakes. How quickly a message can appear depends on that procedure and the operator’s systems.

• Prompt Updates: Revised messages can be published without reprinting.
• Weather-Related Content: Safety advice can be shown when official forecasts or warnings are issued.
• Local Notices: Road closures, event changes or missing-person appeals issued by the relevant authorities.

Static posters compared with digital billboards:

Effective PSA designs catch attention quickly. Keep the message clear and concise, use bold typography and keep text short. Use contrasting colours for readability at a distance, and use simple, relevant images or icons rather than clutter.

Interactive elements such as QR codes or countdown timers can work on screens that pedestrians can stop and look at, such as in malls or plazas. On roadside screens, avoid elements that encourage drivers to look for longer or use their phones. Guidelines:

Balancing these elements helps your PSA stand out and reach its audience safely.
