According to AstroSwami the meaning of your Dream is:
A truck can indicate hard work. Are you driving the truck? If it is weighted down, you may be working very hard and have a large "load" to carry. However, a truck can mean hard work in a positive way. If you are happily driving the truck, you are easily "carrying the load.' A truck coming toward you may be telling you that a large job is looming over you and making you feel overwhelmed.
