A sawhorse type of traffic barricade constructed from identical leg units. The legs are equipped with a stop to prevent them from opening beyond a predetermined point. The legs have the cross section of a right triangle, allowing the hypotenuse sides of the legs to nest within each other. The legs may be equipped with complementary convex and concave portions to allow the barricades to be stacked securely atop one another by fitting the portions together.
