The laws of general relativity apply to everything on all scales. However, if you only consider events that are close to each other in space and time, general relativity makes the same predictions as special relativity — including the cosmic speed limit c. That means you will never see something move past you faster than light, but it’s fine for distant objects to move faster than c relative to you.
