9 Things you may do according to the rules
Under the Rules of Golf you may…;
1. Rake irregularities in a bunker before you play your ball out of that bunker, provided this is for the sole purpose of caring for the course and nothing is done to breach Rule 13-2 with respect to your next stroke. Exception 2 to Rule 13-4.
2. Carry a left-handed club, even if you usually play right-handed. Nothing in the Rules disallows this.
3. Borrow balls, tees, gloves, towels etc. from another player during a round (in fact, you may borrow any equipment except a club). Decision 15-1/5.
4. Have more than one caddie during a round, provided that you only have one caddie at any time. Decision 6-4/7.
5. Enter the clubhouse, car park or pro shop during a round without penalty, providing you do not unduly delay play. Decision 6-8a/2.7.
6. Knock down tree leaves with a practice swing, providing you do not actually improve the area of your intended swing. Decision 13-2/22.
7. Test the condition of a bunker, providing your ball does not lie in or touch that bunker, or a similar bunker. Rule 13-4.
8. Roll a ball over the putting green to a fellow competitor or opponent, providing you are not doing so to test the surface. Decision 16-1d/1.
