Any owner of a car that drives his owncar, not once did, and more than once will make such a maneuver as a turn. In the conditions of modern traffic, you need to be able to make a turn in order not to harm both your car and other cars. The article will consider how to make a U-turn.
It should be said that the U-turn can be done inmany places. You may need to turn around somewhere in the yard, where there is limited space, on a narrow road, possibly at a crossroads. Depending on the conditions, the reversal technique can be different. And here it is very important to know how to properly turn. The turn can be in a circle and with the change of movements back and forth. In a circle, you can turn on a large space, that is, on a wide road or at a crossroads. The second option in a limited space.
Basic rules of the turn
So, let's start the technique of making a turn. Before any turn you will need to do an analysis of the traffic situation, that is, check whether there are cars on the road, and also imagine how you will need to turn around, exactly how you need to go at the same time. Consider how to unfold on a wide road and make a turn at the crossroads. Here you can turn around in a circle. Any turn is made at the minimum speed, usually in the first gear, if the car is equipped with a mechanical gearbox. Further, there is such an important concept as the radius of a turn, or what circle you describe with your wheels when you turn. Representing the radius of the turn, you can estimate which circle you describe with wheels.
It is worth saying that the radius of rotation depends onOn how many degrees the front wheels can turn. Of course, the best option is to turn the wheels by 90 °. But in our practice this phenomenon is from the realm of fantasy, because it is unprofitable to make such a turn of the wheels, considering the space saving under the hood, considering the design of the steering gear, etc. At the present time, the maximum angle of rotation of the wheels is 40-45 °. The most common is 41 °.
As for the minimum size of the radiusturn, it is between 4.5 m and 6.5 m. It usually depends on the brand of the car. If you know the radius of the turn of your car, then you only need to calculate the width of the intersection, or the road and then you will know if you will turn around in a circle.
There is one more nuance turning radius will bemuch less on the same car, if the reversal is reversed. For a better orientation, what a reversal looks like in practice and how to design it, a video on the Internet can very clearly show it.
How to make a turn at an intersection
So, the turn at the crossroads. You calculated the possibility of a turn and presented the movement of the car in a circle. But at the crossroads there may be other cars. And to avoid a collision, there are certain rules for reversal. Moreover, there are places where it is forbidden to make a U-turn. They are indicated by special signs of the prohibition of reversal. Before turning, you need to occupy the leftmost lane, and turn on the left turn.
As for going to the middle of the intersection beforeby turning it is better to make a turn, starting from the place of the beginning of the intersection. Usually it all depends on the size of the intersection. You turned on the left turn, but you can make a turn when you have an advantage on the road. What is meant? If the intersection is regulated by a traffic light, then you can make a turn on your green color, while passing the oncoming cars. If you are on the main road, depending on priority signs, or road coverage, you also need to pass oncoming cars. But, if you are at an equivalent intersection, then the turn will do, guided by the rule of the right hand.
If there are counter cars, then skip them,then you need to skip the car on the right and then make a turn maneuver, leaving us a crossroads. Turning can also begin with the right lane, but in the event that the dimensions of your car do not allow you to do this from the extreme left lane. After a turn, occupy the extreme right lane, because you have a low speed, and you can interfere with other participants in the movement.
How to make a U-turn on the road
But turns on the roads become significantlyIt is more difficult when space is not enough to turn around in a circle. You need in this case, also turn the left turn and lower the speed. Then maximally turn the wheels to the left and turn the car until you reach the end of the road. Then turn the wheels on the right and, turning on the rear gear, drive back. And then the first gear and the forward motion, with the wheels turned to the left. If these movements are sufficient for a turn, then the turn is completed, if not, then it must be repeated.
