Is there a script for moving a rigidbody without using a character controller?

Does anyone have a script for rotating and translating a rigidbody without a character controller. I have one that rotates it but that is all. I need it to be controllable like a car. It needs to rotate on the Y and translate along the X and Z.

All the functionality of a RigidBody is described in the Unity Scripting Reference:

Functions such as AddForce can be used to move a rigid body in the desired way.

If you are new to Unity and scripting then I suggest you look at the tutorials located here to learn what you need to know to create some basic gameplay:
