This has been a perennial problem, because too many people don't know that "the law" is not uniform throughout the world. Virtually all questions require some specification about jurisdiction (which might be implicit in the question itself, such as a question about Florida parking law or Japanese food laws). Even then, people especially in the US do not understand that certain matters are governed by state law and not federal law; and yet, there are currents of uniform law throughout the US to the point that statutes in multiple states can be verbatim identical.
Although you can always VTC on the grounds "too broad" (worst solution) or ask for a jurisdiction, such requests frequently go unheeded. I think the best solution is to make an educated guess about the intended jurisdiction, pick one or two illustrative situations, and make it clear that the jurisdiction matters. Dale M. defaults to Australia, I default to US and Washington, and I think this is the right way to deal with the problem (naturally, since I do it). Adding information that informs the reader about the range of variation between jurisdictions is usually helpful.
