Answer:

What is the preferred steering method to help reduce the possibility of losing control?
slava [35]
Steering is simply defined as a mechanism in a vehicle or vessel that makes it possible to steer in different directions. The preferred steering method that will help reduce the possibility of losing control is the push pull method. It is also called hand-to-hand. In this method, each hand remains on its respective wheel side. Whenever you are turning left; your left hand begins by pulling in a downward motion from the 10 o'clock position to the 9 o'clock position. <span />
