Form three complete tires by placing a small oval inside a larger oval. Attach the bottom of an unfinished oval to the bottom of the front tire. To the left of the two rear tires, sketch another incomplete oval.
On the far left, draw two unfinished ovals that overlap slightly and are connected at the bottom. Above and to the left of the rear tires, sketch one long straight line from right to left and one short line that is slanted and upright.
