About this icon

Use the Bus Alert Outline icon

The Bus Alert Outline icon from Material Symbols fits naturally in travel booking platforms, fleet management dashboards, logistics apps, ride-hailing UIs, and route planners. Its outline style makes it ideal for app navigation bars, toolbar buttons, form labels, and UI controls where clarity at 16–24px is critical.

Open it in IconStash to set stroke color via presets or a custom hex value, choose an exact pixel size (16–512px), control stroke width (0.1–3px), and preview against dark, light, or checkered backgrounds before downloading.

Export formats

Copy clean SVG vectors with one click, generate custom-size PNG files from 16px to 512px, export JSX/React components ready to paste into your project, or use the icon as a CSS background-mask for flexible theming.

All exports are based on the same editable vector — so the Bus Alert Outline icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.

Design & UX integration

Aesthetic characteristics

Bus Alert Outline belongs to Google's Material Symbols, which replaces static icon files with a variable font. Weight, Fill, Grade and Optical Size are all adjustable axes, so one file covers what used to need five. Optical Size is the most useful: the glyph is subtly redrawn for small sizes rather than just scaled down.

UX best practices

In booking, fleet and logistics interfaces, use the Bus Alert Outline icon as a supporting glyph beside a text label. Mode-of-transport shapes are genuinely ambiguous across regions — a "train" glyph is drawn differently in Europe, Japan and North America — so never let the icon carry the meaning on its own.
