Draw the tire part of the truck first: draw two circles on the paper, then leave a certain distance between the two circles, and then connect the two circles with a straight line to draw the first half of the truck body: draw a rectangle and trapezoid on the first circle, and erase the overlapping lines of the two figures with an eraser.

Draw the front half of the truck body: draw a rectangle and a trapezoid on the first circle, and erase the overlapping lines with an eraser. Draw the three-dimensional part of the truck pocket: on the basis of the drawn rectangle, draw a rectangle and a right triangle on it, and draw the driver's seat part of the truck: draw a trapezoid slightly smaller than the second step on the inner side of the front half of the truck body, draw a straight line and an arc below the hypotenuse of the trapezoid to represent the steering wheel, and add a small semicircle on the door.
