A traffic control method in which a two-dimensional, full-sized replica of a police car is placed relative to a road and its passing traffic so that the replica appears to be an actual police car to drivers. The method generally includes providing the replica to have a size and configuration corresponding to an actual police car, transporting the replica to a location where the replica is seen from a road, and supporting the replica at the location so that the replica is located, oriented, sized, and configured so as to appear to be the actual police car on traffic control duty to drivers on the road. The replica is supported so that it can be rapidly relocated to multiple additional locations to regulate traffic.
