On many roads, you will find signs indicating the presence of an obstacle on the road, either on both sides or on the right or left side only.
 Therefore, I will put the signs that indicate this here and how to behave correctly with her when meeting her.

The following blue and yellow signs are permanently placed on the sides of the road and indicate that there are obstacles on the road
 The red and yellow boards are placed temporarily in case there is work on the road or on the side of the road.

There can be only one sign on the sides of the road, or both signs depending on the direction of the obstacle.

Panel A is placed on the left side and panel B is placed on the right side.

Example

Also, in some streets, the obstacles are on one side, for example the following picture

If the obstacles are on your side and there is oncoming traffic, you must wait until the traffic crosses from the opposite side
 
 If the obstacles are on the left side, in this case you must walk from the opposite side and wait until you cross.
 
 The following signs are permanently placed on the road. They also warn of the presence of an obstacle and mean that the road will become narrow.
