A dream where a vehicle is being driven symbolizes your choice of direction in life.

If you are a passenger in the vehicle then it implies that you are being too passive or that you are feeling powerless in some part of your life.

To be driving backwards implies that you are being too ruthless in some part of your life or you are experiencing obstacles or setbacks.

If your view ahead while driving isn't clear then it suggests that you need to set yourself clear goals.
