Diagnoses

Here is how rule engines diagnose the autoplay issue for HTML element 267 of the Clean Air Task Force (CATF) page.

1. You have defined <code>autoplay="true"</code>. Individuals who use screen reading software can find it hard to hear the speech output if there is other audio playing at the same time. Allow the user to turn off videos/sounds (especially if they last more than 3 seconds) that start automatically when a page loads.
