Which of the following statements correctly describes the function of a roadblock ad?

A roadblock ad is designed as a powerful advertising tool that takes over a user's screen, occupying the entire screen before any other content is visible. This type of ad is intended to capture the user's full attention, ensuring that they see the message without distractions from other background content. By blocking all other ads, it creates a high-impact experience, often used for brand awareness or major announcements.

The characteristics of roadblock ads include their ability to cover the full visual field of the display, making them particularly noticeable. This contrasts with other types of ads that may appear in less prominent positions or that allow for user interaction, such as scrolling or immediate skipping. Roadblock ads are effective in ensuring that users engage with the promoted content solely and can create an impression that is difficult to ignore. Thus, the correct description of a roadblock ad highlights its capacity to occupy the entire screen, making it a compelling choice for advertisers seeking maximum visibility and impact.
