Idea of In Transit Icon
It's a drawing of a moving van. It's being viewed from one side, so there are only two wheels present. There are five parallel horizontal lines drawn on the top of the back of the van, to simulate movement.
This In Transit 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.
