WCAG 3.0 is an active W3C Working Draft in development by the AGWG. Requirements, assertions, the conformance model and reporting tiers are still being developed and may change. The latest published draft is the 10 September 2026 Working Draft; this site follows the editorsโ€™ draft, which also includes exploratory provisions.

developing Core requirement

Trigger Warning Available

Group: animation-and-movement • Guideline: avoid-physical-harm

Summary in Plain English

Where content contains triggers, a warning comes before the user reaches them, and there is a way to get the same information without the triggering content.

Why It Matters

A warning alone still forces a choice between the content and the trigger. Providing an alternative route means people with PTSD, anxiety disorders or phobias can get the information without the exposure.

Scope: When This Applies

The draft's own conditions, quoted from guidelines/groups/animation-and-movement/avoid-physical-harm/trigger-warning-available.md.

Applies when

  • triggers are present.

Notes in the draft

Triggers are flashing, motion lasting more than 5 seconds, and pseudo-motion.
