Scale models can be as simple or intricate as desired. They are particularly useful for situations involving vehicles that move in several directions, such as backing up then moving forward, before an accident occurs. Scale models are more expensive than diagrams but have the advantage of depth. The production of a scale model can be moderate to expensive. The cost is dependent entirely upon the size of the scene to be presented and the number of items that will be shown.
Costs can increase if the model is to have any moving parts or lighting installed.
Scale models tend to be fairly delicate so care must be taken in handling and shipping should be held to a minimum. Video animations are a new trend in litigation and still expensive. Not all accident situations lend themselves to animation. They best show a driver's view and collision avoidance tactics in simple scenarios. This type of exhibit, properly prepared, can almost take the jury to the scene.
