This is my second favorite one. Simple and clear. Im not sure what else you can do to it, except maybe incorporating something with a truck icon somehow. Maybe some other color variations like red or blue perhaps. Im really on the fence with yours because I do like the design and the simplicity of it.
Hello James, thank you so much for considering my design. Actually if you look closer to the icon, there's a hint of a truck at the upper part of the helmet. :) Will send variations in awhile.
