What Is the 90-Degree Rule in Golf?
The 90-degree rule is a golf-course cart policy: stay on the path until you are even with your ball, turn straight toward it, and return to the path the same way.
Short answer: stay on the path, then turn at a right angle
The 90-degree rule means you keep the golf cart on the cart path until you are approximately even with your golf ball. Then, if course conditions and signs allow, you turn off the path at a right angle, drive directly to the ball, and return to the path by the same route. It limits how much cart traffic crosses the turf while still letting players reach their balls.
How to follow the rule
1. Keep driving on the path until you reach the point alongside your ball. 2. Check for ropes, signs, wet areas, and other restrictions. 3. Turn approximately 90 degrees off the path and take the shortest practical route to your ball. 4. After your shot, return to the path the same way. 5. Continue using the path unless the course tells you the rule has changed. Do not drive across the fairway to reach another player’s ball unless course policy allows it.
Why golf courses use the 90-degree rule
The policy can reduce unnecessary cart travel over grass while allowing access near a player’s ball. Courses may use it when turf is vulnerable or conditions are wet enough to need care but not so wet that carts must remain on paths entirely. The superintendent or course staff may change the policy by day, hole, or area depending on conditions.
Is the 90-degree rule a law?
No. It is a course-specific operating rule, not a general traffic law for public roads. Follow the course’s signs, ropes, staff instructions, and cart-path-only notices. If the course says paths only, do not drive onto the grass even when you are level with your ball. If you are unsure, ask the pro shop before starting.
Common mistakes to avoid
Do not leave the path early, take a diagonal shortcut across the fairway, drive through a roped-off area, or assume the rule applies to every hole. Keep a safe distance from greens, tees, bunkers, and other players. On a course with accessible-cart accommodations, ask staff which routes and restrictions apply to your cart and mobility needs.
Frequently Asked Questions
When may I leave the cart path under the 90-degree rule?
When you are approximately even with your ball, and only where the course permits carts to leave the path.
Do I drive back to the path the same way?
Yes. The usual instruction is to return to the cart path along the same route you used to reach the ball.
Does the 90-degree rule apply at every golf course?
No. It is a course-specific policy. Follow local signs and staff instructions; cart-path-only rules take precedence.
