Replying to Speed of light

OK this have been on my mind lately, let's just say you were driving your car through space at the 3 times speed of light, and you had your headlights on. Would your headlights fall behind your car, because you're going faster than the speed of light? Or would the initial velocity of your car be added to the light, making it 4x the speed of light, can light have an initial velocity? It's confusing me, because can light go faster than the speed of light? can it have an initial velocity?
