Signs, Flags, and Lights Requirements

If, and only if, the trip originates outside of Indiana, can color combinations or wording approved by other states be permitted.
Flags
For flags, 2 (red or orange) must be placed at the widest extremities of the vehicle or load. Flags must be in good condition, plain or orange with no figures, and must be 18 inches square, placed so that any approaching traffic can see them.
Lights
Every oversize and overweight permit load must well displayed functioning amber light(s) on the tractor that is oscillating, rotating, or flashing. Lights must be placed at the outer edges and not be less than 6 feet above the roadway.
Front lights may be mounted on the towing vehicle at the furthest extreme of any safety device, but not extend beyond the mirrors. They must be double-faced lamps that are visible both front and rear. Lights must be visible from 500 feet in normal sunlight.
