Boys in particular will love these cool coloring pictures of cars, though girls will also quickly discover their fondness of these free printable images. A car coloring sheet is an excellent way to train spatial vision and thinking skills at an early age and improve motor skills at the same time. Car coloring pictures in particular sometimes have small areas and fine details that require careful coloring. This calls for maximum concentration and accuracy as your child colors the area of the car within the outlines. There is, however, a free choice of colors - green, yellow, purple or any other color from the rainbow- the main thing is that the little ones have fun and live out their creativity when coloring in the car.
