Crossroad with traffic lights
At a crossroads controlled by traffic lights, the traffic lights indicate who has priority. If the traffic light is green, you’re allowed to drive through. If the light has been green for a while, make sure you can stop when it turns orange. With an orange light you have to stop, you may only drive through if you are already so close that you can not stop safely. With a red light, you must stop and wait until the light turns green.
At a green light you can drive on
