If you know or are virtually certain that your original ball is OOB or in a water hazard, you are right and the 2nd ball will be 3 off the tee. However if there is any doubt then you are still entitled to play a provisional ball. It's really just a means to speed up play and to stop you having to walk back to the teeing ground or the previous spot if the original ball is OOB or lost outside a water hazard.
To Quote yourself please show me were it says this in the Rules??
Ok I'll help you, it does not the correct rule is 27-2 - if a ball may be lost outside a water hazard or may be out of bounds, to save time the player may play another ball provisionally in accordance with Rule 27-1.
So if a ball is "virtually certain to be out of bounds" you are permitted to play a provisional.
