SIGNS, FLAGS & LIGHTS: “Oversize Load” signs are required for all oversized loads at the front of the tractor at a height of 5′ from ground level (or as high as practicable on the vehicle or load if it cannot accommodate the 5′ height), and at the rear of the vehicle at a height of 5′ to 7′ from ground level (or as high as practicable on the vehicle or load if it cannot accommodate the 5′ to 7′ height). Signs are not needed for overweight only loads. Flags must be displayed on all four corners of all overwidth loads, and at the extreme ends of all protrusions, projections, or overhangs. When night movement is allowed, loads projecting beyond the sides of the vehicle must have amber lights visible from the front and side at the outermost extremities. Rearmost edge of the projecting load must be marked with a red lamp visible from the rear and side.
