Which one of the following is most likely to cause an emergency situation?

The correct answer is: Practice skidding on quiet roads.

Let us explain why this option is most likely to lead to emergencies. First, even on seemingly quiet roads, there is still a risk of unexpectedly encountering pedestrians or other vehicles. Second, practicing skidding may mean that the vehicle is at the edge of the driver's control or beyond their control, significantly increasing the likelihood of an accident. Finally, such behavior may cause the driver to lose control of the vehicle, resulting in injuries to themselves or others.
