This page shows the different variations of the Kierowca from an Icons8 icon pack. Feel free to resize and recolor the icon, and then download the icon in PNG format for free. Icons are available in PNG and vector.
The logo kind of looks like a person. There is a circle on the top depicting a head, and directly below it is a hexagon with a semi circle cut out of the bottom. Below that semi circle is another semi circle inside of it.
