Never drive the cart within hazard boundary lines, or within about 10 yards of water hazards or bunkers, or within about 50 yards of greens (unless you're on a designatedcart path, of course). These areas are especially susceptible to damage by the wheels of golf carts. Never drive onto or close to tee boxes, either, unless on the cart path.
Never drive the cart through mud, on or off the fairway.
Never drive through casual water on any part of the golf course (unless it's a little bit of water over a paved cart path). The wheels of the cart can do serious damage to the turf, including leaving ruts, in wet areas.
Never go joyriding in the golf cart. In other words, don't act stupid! People do get injured in cart accidents. See golf cart safety for specific suggestions.
About the golf cart’s etiquette, there are still a lot. And we will tell you more nest time.
