Idea of Roadblock Icon
A roadblock is something to stop people from going on it. If you didn't want someone to go on a road, you'd put a roadblock to block off anyone from getting on it. It's a sturdy piece of wood, all put together with yellow warning flashing things to say don't get on this road!
This Roadblock icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 6,200 icons, all in the same style and quality.
