The tuk-tuk may have a sheet metal body (painted mild steel) or open frame with canvas roof and drop-down sides. Some have ornate tin ornamental hammerings or carvings for decoration. The roof may be either mild steel or a water-proofed canvas, riveted to round tubing. Water-proof removable sides can be added in the rainy season. Resting on three small wheels (one in front, two on the rear), there is a small cabin for the driver in the front and seating for three in relative comfort in the rear. They are very maneuverable and can turn around in one lane of traffic with room to spare
