Which of the following practices is illegal when operating a personal watercraft (PWC)?

Operating a personal watercraft (PWC) too close to other vessels is illegal as it can pose significant safety risks to all individuals involved. Maintaining a safe distance from other boats helps prevent collisions, reduces the chances of accidents, and ensures the safety of the operator as well as other boaters. Regulations often require maintaining a minimum distance from other vessels, especially in crowded or congested areas, to promote safe navigation practices.

In contrast, riding alone on a PWC, using the safety lanyard, and wearing a life jacket are either legal or recommended practices aimed at ensuring the safety of the rider. Riding alone is permitted, provided the operator is capable of handling the PWC alone. The use of a safety lanyard is a crucial safety feature that stops the engine if the operator falls off, which enhances safety during operation. Additionally, wearing a life jacket is mandated for personal watercraft operators in many states, including Tennessee, as it greatly increases the chances of survival in case of an accident.
