If you’ve ever driven a golf cart and a marshal reminded you to “follow the 90 degree rule,” you might have wondered exactly what that means and why it’s important.
In this guide, we’ll explain what’s the 90 degree rule in golf, why golf courses use it, how to follow it correctly, and how it impacts your game.
What’s the 90 degree rule in golf?
The 90 degree rule in golf is a course management rule that tells golfers how to drive their golf carts to protect the fairway.
Definition:
When the 90 degree rule is in effect, you must drive your golf cart along the cart path until you are even with your ball (at a 90-degree angle), then turn directly toward the ball, cross the fairway, and return to the cart path after your shot.
In simpler terms: Stay on the cart path as much as possible, only entering the fairway at a right angle to your ball to minimize turf damage.
Why Do Golf Courses Use the 90 Degree Rule?
Golf courses enforce the 90 degree rule to:
- Protect the turf – Continuous cart traffic in the same areas can damage grass.
- Prevent soil compaction – This helps the fairway stay healthy and playable.
- Reduce maintenance costs – Less damage means less repair work for the grounds crew.
- Ensure fairness – Keeps the course in good condition for all players.
How to Follow the 90 Degree Rule Correctly
Here’s a step-by-step guide for following the 90 degree rule in golf:
- Drive along the cart path after your tee shot.
- Stop when you’re level with your ball (even distance).
- Turn 90 degrees toward your ball and cross the fairway.
- Play your shot.
- Return to the cart path along the same 90-degree route.
Tip: Always look for signs or ask the starter/marshal if the 90 degree rule is in effect for that day.
