Which of the following should a driver avoid when making movements on wet roads?

When driving on wet roads, it is crucial to maintain control and stability of the vehicle to prevent skidding and loss of traction. Therefore, avoiding harsh and erratic movements is essential for safe driving. Such movements can lead to a sudden shift in the vehicle's balance, increasing the likelihood of hydroplaning, which occurs when the tires lose contact with the road surface due to excess water. Smooth and gradual steering allows the driver to maintain better control, while light brake applications can help in slowing down without locking up the wheels. Staying alert enables the driver to respond to changing conditions effectively. Thus, avoiding harsh and erratic movements is the correct approach for ensuring safety on wet roads.
