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 is a Roadblock icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,900 icons, all in the same style and quality.
