White Stakes
White stakes mark the boundary of the golf course — beyond them begins out of bounds.
The white stakes are the strictest marking on the course. Everything inside the line is in play, everything beyond it is out of bounds. The boundary runs, conceptually, along the inner edge of the stakes at ground level. Your ball only counts as out of bounds when it lies completely beyond this line. If even a millimetre of it still hangs over the course, you keep playing — and you may not simply move the stakes themselves. If the ball lies outside, the harshest penalty in the Rules of Golf follows: a Penalty Stroke plus loss of distance.
In practice this means: if your drive heads towards the white stakes, you immediately announce a provisional ball and play another. If you find the first ball out of bounds or not at all, you continue with the provisional — counted from the tee, that is then stroke four. An example: your first ball comes to rest half a metre beyond the line in the bushes. It is out of bounds no matter how good a lie it has there. There is no dropping as with a water hazard, only the return to the spot of the last stroke.
The most common mistake is confusing them with other markings. Red or yellow stakes mean penalty areas with drop options; white means out of bounds without a drop. Many clubs soften the harsh penalty with a local alternative rule: then you may drop, for a two-stroke penalty, where the ball crossed the boundary. Whether this rule applies is stated on the Scorecard or on the notice in the club office. The term Lost Ball also helps with handling balls that cannot be found.
FAQ
May I move a white stake if it interferes with my swing?
No. White stakes count as integral parts of the course; you may neither remove nor bend them. You must play the ball as it lies or declare it unplayable and drop with a penalty stroke.
When exactly does my ball count as out of bounds?
Only when the ball lies completely beyond the imaginary line along the inner edge of the stakes. If even a millimetre of the ball still hangs over the course side, it is in play. The stakes themselves stand out of bounds, so a ball directly against a stake can still be in play.
What do I do if my drive flies towards the white stakes?
Immediately announce a provisional ball and play another before you go searching. This saves you the long walk back to the tee if the first ball is out of bounds or cannot be found. Many clubs also allow a local alternative rule: then you drop, for a two-stroke penalty, where the ball crossed the boundary — whether that applies is stated on the notice in the club office.
