Abstract: A collapsible traffic control sign in the form of an arrow board for providing an alert warning to approaching traffic includes a collapsible frame including first, second and third frame members and four cooperating link members. Each link member is connected at opposite ends with a pivotal connection to a different one of the frame members. In a closed condition, the traffic control sign orients each of the three frame members in a substantially parallel and contiguous arrangement. When opened, the frame members are spaced apart and extending between each pair of frame members are two link members. The link members are oriented such that each pair creates the shape of a pointed arrow. Three light subassemblies are assembled to each of the four link members and the lights are illuminated by battery power from a vehicle by means of a cigarette lighter adapter.
