Success Criterion · WCAG 2.2.2
For moving, blinking, scrolling, or auto-updating information that starts automatically, lasts more than five seconds, and is presented in parallel with other content, there is a mechanism to pause, stop, or hide it, or to control the frequency of the update.
Goal
Give users control over moving, blinking, scrolling, or auto-updating content.
What to do
If content moves/updates automatically for more than 5 seconds (and is not essential), provide controls to pause, stop, or hide it.
Why it matters
Movement and auto-updates can distract users, make reading difficult, and interfere with assistive technology.
Success criterion
Summarized directly from the official Understanding document so teams can quote the requirement accurately.
For moving, blinking, scrolling, or auto-updating information, all of the following are true: (1) Moving, blinking, scrolling: For any moving, blinking or scrolling information that (a) starts automatically, (b) lasts more than five seconds, and (c) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it unless the movement, blinking, or scrolling is part of an activity where it is essential; and (2) Auto-updating: For any auto-updating information that (a) starts automatically and (b) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it or to control the frequency of the update unless the auto-updating is part of an activity where it is essential.
Intent
Benefits
Why it matters
Summaries drawn from the Understanding document help you socialize impact statements with product stakeholders.
Carousels may rotate before users finish reading.
Auto-refreshing lists may change under focus, causing users to lose place.
Moving banners may obscure other content or make it hard to concentrate.
Exception guidelines
Document the rationale for each exception and note which alternative support you provide.
Movement or auto-updating is essential to the activity.
Requirement
Only when essential to the activity itself.
Users need control over content that moves or updates automatically (carousels, tickers, live-updating panels). Provide pause/stop/hide controls (or update frequency controls) unless the motion/update is essential.

Examples
Share pass/fail snapshots to coach designers, engineers, QA, and content authors.
Pass
Carousel includes Pause button and does not auto-advance when paused.
Fail
Carousel auto-advances every 3 seconds with no pause control.
Pass
Live feed has “Pause updates” toggle or “Update every: 10s/30s/Off.”
Fail
Feed refreshes automatically and reorders items while user is reading.
Pass
Scrolling ticker can be paused or hidden.
Fail
Ticker scrolls continuously with no way to stop it.
Evidence to keep
Capture artifacts for VPATs, procurement reviews, and regression testing.
