How do I serve in wheelchair tennis?

• Be stationary immediately before you start the service. You are then allowed one push before you strike the ball.
• Throughout the serve, your wheels must not touch any area other than behind the baseline, between the imaginary extensions of the centre mark and the sideline.
• If a conventional serve is physically impossible for a Quad player, the player or another person may drop the ball and let it bounce before it is struck. The same method must then be used for the whole match.

Using your feet or lower limbs against the ground or a wheel while serving loses the point (unless you are permitted to push with one foot, in which case that foot must stay off the ground from the start of the service motion until the racket strikes the ball).
