The video explains traffic controller signals, emphasizing that their signals override traffic lights and signs. There are three main signals:
1. Hand raised up: Stops all traffic in every direction, with exceptions for vehicles already in the intersection.
2. Arms extended sideways or right arm bent in front: Prohibits movement from behind and in front of the controller, allowing traffic to flow from the sides.
3. Right arm extended forward: Stops traffic from behind and to the right of the controller, permitting movement from the front and left.
The video also covers additional signals and stop requests by police officers using various methods. It concludes with an encouragement to watch the next video for more information.
