Lateral Relief
Lateral relief in golf is a one-stroke relief option that lets a player drop a ball within two club-lengths of a fixed reference point, no nearer the hole. It applies when a ball lies in a red penalty area or has been declared unplayable.
What is lateral relief?
Lateral relief is a relief procedure, not a single rule. It appears in two places in the Rules of Golf: Rule 17.1d(3), which covers red penalty areas, and Rule 19.2c, which covers an unplayable ball. In both cases, the player gets a relief area two club-lengths wide, measured from a defined reference point, and must drop a ball into that area at knee height. The penalty is always one stroke.
The point is straightforward: a sideways escape from trouble. Back-on-the-line relief sends the ball further from the hole on a fixed line, whereas lateral relief keeps it roughly level with the trouble spot, just to one side. That sideways direction is what “lateral” refers to.
According to R&A Rule 17.1d(3), the reference point for a red penalty area is the estimated spot where the original ball last crossed the edge of the penalty area. For an unplayable ball under Rule 19.2c, the reference point is the spot of the original ball itself. The two-club-length measurement is taken using the longest club in the bag other than the putter, per the USGA’s Rule 14.3 procedure.
When lateral relief applies
Three specific situations trigger this option under the Rules of Golf.
The first is a red penalty area. When a ball is in (or known to be in) a penalty area marked with red stakes or lines, the player has three relief options under Rule 17.1d, each costing one penalty stroke. Lateral relief is the third option. It does not apply to yellow penalty areas, which have only stroke-and-distance and back-on-the-line relief.
The second is an unplayable ball in the general area. Under Rule 19.2c, a player who declares a ball unplayable can drop within two club-lengths of where the ball lies, no nearer the hole, for one penalty stroke. The R&A confirms that this option is unavailable for a ball in a penalty area, where Rule 17 takes over.
The third is an unplayable ball in a bunker. The same lateral relief option exists under Rule 19.3, but the dropped ball must remain in the bunker. A separate two-stroke option lets the player take back-on-the-line relief outside the bunker if they want to escape it entirely.
How to take lateral relief
The procedure is the same whether the ball is in a red penalty area or has been declared unplayable, with only the reference point changing.
First, identify the reference point. For a red penalty area, this is where the ball last crossed the edge, usually estimated rather than measured precisely. For an unplayable ball, it is the spot where the ball lies, or the spot directly below the ball if the ball is off the ground (in a tree, for example).
Second, measure two club-lengths from that point using the longest club in the bag other than the putter. The relief area extends in any direction within that radius, but cannot be nearer the hole than the reference point.
Third, drop the ball from knee height inside the relief area. Under Rule 14.3, the ball must come to rest within the relief area for the drop to be valid. If it rolls out, the player re-drops once. If the second drop also rolls out, the ball is placed at the spot where it first touched the ground on the second drop.
One accessibility note worth flagging: Rule 25.4m expands the lateral relief area to four club-lengths for players who use a wheeled mobility device.
Lateral relief vs back-on-the-line relief
Both options carry a one-stroke penalty and both are available for a ball in a red penalty area or declared unplayable. The differences sit in where the drop ends up and how it is measured.
| Aspect | Lateral relief | Back-on-the-line relief |
|---|---|---|
| Penalty | One stroke | One stroke |
| Reference point (red penalty area) | Where ball last crossed the edge | Where ball last crossed the edge |
| Reference point (unplayable) | Spot of the original ball | Spot of the original ball |
| Direction of relief | Sideways from the reference point | Backwards on a line through the hole and reference point |
| Size of relief area | Two club-lengths in any direction | One club-length around a chosen spot on the line |
| Distance from the hole | Same or further, never nearer | Player chooses how far back |
| Available in yellow penalty area? | No | Yes |
Lateral relief is quicker. The player stays at a similar distance from the hole rather than walking back along a line. Back-on-the-line gives more flexibility: the player picks the yardage by choosing how far back to drop. Which option works best comes down to the lie and the shot the player wants next.
Lateral relief vs lateral water hazard
The phrase “lateral water hazard” still circulates in golf conversation, but it no longer exists in the Rules of Golf. The 2019 Rules modernization replaced “water hazard” and “lateral water hazard” with the single broader concept of a penalty area, marked either yellow or red.
Before 2019, lateral water hazards were marked with red stakes and had the same sideways relief option that exists today. The change in language did two things: it removed the requirement that a hazard contain water, and it folded the lateral relief option into a single penalty area framework. Older articles and signage may still use the defunct term, but they are generally describing what is now called a red penalty area.
Common mistakes with lateral relief
A few errors come up often enough that they’re worth flagging.
Dropping closer to the hole than the reference point. The two-club-length area is restricted to spots no nearer the hole. A drop that ends up even slightly closer to the hole is in the wrong place.
Using the wrong reference point in a penalty area. Some players mistake the spot where the ball came to rest in the water for the reference point. The correct point is where the ball last crossed the edge, often well away from where it ended up.
Trying to take lateral relief from a yellow penalty area. Yellow penalty areas have only two relief options: stroke-and-distance and back-on-the-line. Lateral relief is reserved for red penalty areas.
Assuming lateral relief guarantees a playable lie. It doesn’t. The ball must come to rest in the relief area, but that area might still contain a bush, a slope, or another awkward spot the player can’t swing from. The player can then take further lateral relief for another penalty stroke, or choose a different option.

Frequently Asked Questions
Is lateral relief free?
No. Lateral relief always costs one penalty stroke, whether taken from a red penalty area under Rule 17 or from an unplayable ball under Rule 19.
Can a player take lateral relief from a yellow penalty area?
No. Yellow penalty areas allow only two relief options under Rule 17: stroke-and-distance and back-on-the-line. Lateral relief is restricted to red penalty areas.
Does lateral relief guarantee a playable lie?
No. The ball may end up in another bad spot inside the relief area. The player can take further lateral relief, but each drop costs another penalty stroke.
What is a lateral drop in golf?
“Lateral drop” is a casual term for the lateral relief procedure: a one-stroke drop within two club-lengths of the reference point, no nearer the hole.
Can a player take lateral relief on the opposite side of a red penalty area?
Only when the Committee has adopted Model Local Rule B-2. Without that local rule, lateral relief is restricted to the side where the ball last crossed.
How is a club-length measured?
A club-length is the length of the longest club in the bag other than the putter, usually the driver. This is the standard measurement under USGA and R&A Rule 14.3.
