Vehicle U-turn skills
1. Turn around a narrow road
When the car is running on a narrow road, it should be reversed by the combination of forward and backward method. The operation essentials are: when the vehicle is approaching the turning point, a left turn signal, reduce speed in advance within a reasonable distance, change into low gear driving on the right side of the road, at the same time, open the left turn signal, observe the road conditions, such as turn will not affect the car to the vehicles on the road, you you can quickly turn to the left foot of the steering wheel, the vehicle slowly toward the left side of the road, to be close to the front street (about 1 meters away from the road), two to three quickly swing right direction and parking.
