Which of the following is not a proper steering technique?

Box style steering is not a proper steering technique due to the potential for reduced control and effectiveness while navigating a vehicle. This method involves moving the steering wheel in a rectangular motion, which can lead to slower response times when making turns or adjustments, particularly in emergency situations.

Effective steering techniques, such as hand-over-hand and push-pull steering, emphasize maintaining better control of the vehicle. Hand-over-hand steering allows the driver to turn the wheel effectively and return it to a neutral position, while push-pull steering facilitates smooth and controlled movements either for turns or during straight driving. One-handed steering is generally considered appropriate only in specific situations, such as driving in a straight line or when using a specific single-handed technique like controlling the vehicle while performing other tasks, but it lacks the control and stability offered by the other methods listed.

In summary, box style steering does not provide the same level of responsiveness or safety as the other techniques, making it an unsuitable choice for proper steering.
