I love cars, just in case you didn't know. And doing a set of vehicles is fun and it's quite simple. Just a few steps and you can get a car, bus, SUV, 4X4 or truck icon easily. And when I am not teaching or making infographics, I am most likely working on one of my 37 cars. Yes, 37, really. Enjoy!
Start with a rounded corner rectangle and fill it with a color.
Duplicate the original shape inline with the first one.
Create a new rounded corner rectangle wider that the the 2 "wheels".
Draw a circle and place it in the horizontal bar, fill the circle with white and duplicate it above the other wheel.
Draw a rectangle a bit narrow than the horizontal rectangle. Apply a stroke of 14 pt with no fill.
Select the top two corners with the Direct Selection Tool and round the corners a little bit.
Then select the upper left corner with the Direct Selection Tool, use the RIGHT arrow to move the point in toward the center. Repeat the process with the upper right corner to bring in the corners to form a trapezoid shape.
Put all the pieces together.
Darken the fill on the wheels, add a light blue to the upper rectangle to show the window.
Use the Direct Selection Tool to move the top of the car down to create a sportier look.
Now you have a sporty car, with a shorter roof.
You can round the top more, add a smaller set of lights inboard of the larger lights to create a sports car icon. This one I also made the tires to make it look more like a sports car.
To make the back of the sports car, add rectangles with a white stroke for tail lights.
To make an SUV or 4X4 look, move the body of the car up, duplicate the main horizontal rectangle and make it half as high. Put a gap between the two horizontal rectangles to show the tires a bit.
To create a small truck, take the main horizontal rectangle and make it twice as high. Add smaller lights under the main lights. Increase the height of the top.
To make the truck a 4X4, move the wheels down to reveal more to create a higher look.
To create a mini-van or a smaller delivery truck. Make a taller top, taller main section. Add a rectangle at the bottom and add another light to the set.
To create a bigger pickup. Select the right half of the truck with the Direct Selection Tool and move everything to the right.
This makes a wider truck and add a rectangle in the middle for a grill.
To create the back of the truck, add vertical rectangles for the tail lights.
Move the wheels down to create a 4X4 truck icon.
Create a bus by making the shapes wider, making the top more square. Adding two sets of circles for lights.
For a bigger truck, add more white rectangles at the bottom, keep the top more square, single lights and a big grill.
And now you have a great set of vehicle icons to choose from and more to make!
