It means the oil pressure is low and serious engine damage can result if you keep driving it. First check the level. If it is low, the oil pump will draw up air instead of oil. Air compresses and can't build pressure in the system. Oil is needed to be under pressure to isolate moving parts from each other and remove heat. Your engine will last as long without oil pressure as your body would without blood pressure.
