What Is the 90 Rule in Golf Carts?

Quick answer: The 90 rule in golf carts means you must keep your cart on the cart path until you are directly even (level) with your ball, then turn and drive onto the fairway at a 90-degree angle — a straight, right-angle path to your ball. After your shot, you return to the path at the same right angle. The purpose is to minimize the distance carts travel on the grass, spreading out wear and protecting the turf, while still letting you drive reasonably close to your ball rather than walking from the path every time.

01 // What the 90 Rule in Golf Carts Means

Under the 90-degree rule, carts stay on the paved path as you move down the hole. When you reach the point on the path nearest your ball, you turn 90 degrees and drive straight across to it, then return the same way. This keeps each cart’s time on the grass short and perpendicular, rather than driving long diagonal lines across the fairway.

02 // Why Courses Use It

The rule exists to protect turf. Carts compact soil and wear grass, especially along repeated lines. By forcing short, right-angle crossings, courses spread traffic evenly and reduce damage — particularly important when the ground is soft after rain or during recovery periods.

03 // 90 Rule vs Cart-Path-Only

• 90-degree rule: You may enter the fairway, but only at a right angle from the path.
• Cart-path-only: The strictest policy — carts never leave the path at all, used when turf is most vulnerable.

04 // How to Follow It Properly

1. Drive along the cart path until level with your ball.
2. Turn 90 degrees and drive straight to the ball.
3. Take your shot, then return to the path at the same right angle.
4. Always obey posted signs and any wet-weather restrictions.
