In this tutorial you will learn how to use the Motion Guide to animate a car, drive it on the road

Next you will need to find two images car and road or use the images below

Car:

Road:

(A cute image, right?)

Step 2: Go to File>Import>Import to Library and select these images from the dialog. Press Ctrl-L to open up the Library panel if you don't see it

Step 3: Place the road image on Layer 1 (the image has the same dimensions as your document), rename this layer Road. Create a new layer and place your car on the right hand side of the road image

Step 4: Use the Free Transform Tool(Q) to rotate our car to fit with the road

Step 5: Create a new Motion Guide layer and use the Pen Tool(P) to draw a path like this (its color is not important)

Step 6: Click on frame 45 and press F6 to place a keyframe there, repeat this step with car and road layers 

Step 7: Click on the frame 45 of the Car layer and move our car to the left hand side of the road. Use the Free Transform Tool to rotate our car a bit

Step 8: Right click on any frame between 0 and 45 of the car layer and select Create Motion Tween. Now you can press Ctrl-Enter to test your result. Notice that you will see our car moving along the path but its direction is not correct

Click on frame 4 of Car layer and press F6 to place a keyframe here, then select the Free Transform Tool to rotate it a bit

Repeat this step with some other frames. You can see my process below

Now press Ctrl-Enter to see your result!

You can use other effects to smoothen the animation. Hope you like this tutorial!
