If you are talking about racing, the rules are governed by the FIS.
For recreational skiing there are rules of etiquette and in the USA (and elsewhere) safety rules are law in some states (such as Colorado's Skier Responsibility Code).
SKI SAFETY EXAMPLE (from?)
1. Respect for othersPeople using the pistes must behave in such a way that they do not put other people in danger or harm them, either by their behaviour or with their equipment 2. Speed and behaviourPeople using the pistes must adapt their speed and behaviour to suit their personal abilities as well as the general terrain and weather conditions, the state of the snow and the density of the traffic 3. Choice of routeA skier or snowboarder coming from behind must choose his route in such a way that he does not endanger skiers or snowboarders ahead. 4. OvertakingOvertaking can be done from above or below and to the right or left, as long as the person doing the overtaking allows sufficient space for voluntary (or involuntary) movements of the person he is passing 5. Entering a marked run and starting offA skier or snowboarder entering a marked run, starting again after stopping or moving upwards on the slopes must look up and down the slopes that he can do so without endangering himself or others. 6. Stopping on the pisteUnless absolutely necessary, a skier or snowboarder must avoid stopping on the piste in narrow places or where visibility is restricted. After a fall in such a place, a skier or snowboarder must move clear of the piste as soon as possible. 7. Going up and down on footPeople who are obliged to go up or down a piste on foot must use the edge of the piste, taking care that neither they nor their equipment is a danger to others 8. Respect for information, markings and signsUsers must take notice of information about weather and snow/piste conditions and respect all markings and signs on the mountain 9.
