Directives
The directives given by authorised persons in traffic must be given as much in the following manner as possible. Here, the traffic controller is usually in the middle of the intersection.

General stop sign
With the general stop sign, the traffic controller has the palm of is hand facing forward. If this sign is made in your direction, you are required to stop. It is not specifically used at intersections, but can also be used, for example, to stop someone for a check.

Stop sign for traffic approaching the traffic controller from the front
At this stop sign it is easiest to imagine extending the arm and see it as a barrier. If you will hit the barrier if you drive straight ahead you must stop. This is the case when you approach the traffic controller from the front.

Stop sign for traffic approaching the traffic controller from the rear
At this stop sign it is also easiest to imagine extending the arm and see it as a barrier. If you will hit the barrier if you ride straight ahead you must stop. This is the case when you approach the traffic controller from the rear.

Stop sign for traffic approaching the traffic controller from the front and rear
This is a combination of the two previously mentioned stop signs. Only traffic from the left and right may continue on.

Stop sign for traffic approaching the traffic controller from the right
At this stop sign it is also easiest to imagine extending the arm and see it as a barrier. Only if you approach this traffic controller from his right-hand side you will run into his arm and must stop.

Stop sign for traffic in the free direction, watch out for traffic in stopped directions, keep intersection clear
This stop sign looks a lot like the general stop sign. The only difference is that the palm of the raised hand is pointing to his head. This is the sign that is given if the vehicles in the moving directions must stop so that the stationary vehicles can drive on.

Reduce speed sign
The traffic controller moves his arm up and down with the palm of his hand facing down.

Crossing patrol’s stop sign with application of sign F-10
Crossing patrol people are only allowed to stop drivers. So, they are not allowed to give any other directives. In most cases these directives are given with a sign, such as in the picture.

In this case, the traffic controller raised his left arm on the side of the moped rider. If you extend this arm, it crosses the road half of the moped rider. That is why they must wait. The blue car may drive on.

Here, the traffic controller raised his right arm on the side of the blue car. If you extend this arm, it crosses the road half of the blue car. That is why they must wait. The moped rider may ride on.
In reality it may happen that other signs are given. Always use common sense. Regardless of the way a directive is given, you are always required to follow them as long as they are given by an authorised person.
