When you are driving on the track or on the road with a dividing strip, you can see the sign showing you where to turn. It is called "where to turn". Most of these bridges between the traffic flows is done in pairs: first, you drive the plot, which unfolds a moving car, and then see the sign and for you - 6.3.1. In most cases such a place to turn has only one lane, so you need to stick to the left side.
There is another sign on which is painted the reverse. It indicates not only the place where you can turn around, but the length of this zone. In the rules, the sign has a number 6.3.2. In this situation, this road section may have two or even more lanes. You need to be careful when you are driving on the most left lane in this situation. Those who go to the right you have to you advantage, so you should skip them. If you are driving fast or don't like to give, choose the right trajectory.
Turn you can perform also and if there are any characters that allow a left turn. It can be mandatory signs: a blue circle with a white arrow indicating the direction of motion. For example, it may be a sign 4.1.3, which shows you just two possibilities for further movement to the left and back.
If you saw on a roadside sign 4.1.5, you can go to these areas or to make a turn.
Sign 4.1.6 not allow you to go straight. But you don't necessarily have to rotate. Nobody restricts you in the desire to turn around and go in the direction from which you came. The above signs are at the crossroads in front of which you saw them.
In addition to the circular signs on a blue background before making a turn you should also pay attention to the signs "directions of movement on the lane". These signs are square or rectangular in shape. On a blue background painted white arrows showing you which direction you can go in the lane. The principle is the same as prescriptive signs: if allowed to turn left, then turn to do it too. If a sign permits the turn left from second lane, here turn to execute only from an extreme left row.
