In a serpentine driving exercise, what could result in a penalty?

In a serpentine driving exercise, hitting or brushing a marker can result in a penalty because it demonstrates a lack of control and precision while navigating the course. The exercise is designed to test a driver's ability to maneuver the vehicle accurately through tight turns and around obstacles. Striking a marker indicates that the driver failed to maintain a proper path, which is a critical aspect of demonstrating effective driving skills. Observing the boundaries set by the markers is essential for both safety and the successful completion of the driving task. Thus, any contact with a marker signifies an inability to execute the required maneuvers within the designated parameters of the course.
