Here they are and are used especially at night 🌃 1.flashing red-vehicles are to come to a stop then check any oncoming traffic or pedestrian then proceed to cross if the road is clear. 2.flashing yellow-means slow down and check if the road is clear to cross esp for pedestrians and also for drivers esp at night. 3. Flashing green- These are always used where the traffic light doesn't have a yellow light in it.so it's like a 'wait'
