Case: Truong v. Nguyen1
Facts: On a warm California day, there were about 30 personal watercraft (jet skis) operating on
Coyote Lake. The weather was fair and visibility good. Anthony Nguyen and Rachael Truong went for
a ride on Anthony’s Polaris watercraft. Cu Van Nguyen and Chuong Nguyen (neither of whom were
related to Anthony) were both riding a Yamaha Waverunner. Both jet skis permitted a driver and
passenger, each seated. The two watercraft collided near the middle of the lake. Rachael was killed,
and the others all injured.
Rachael’s parents sued Anthony, Cu Van, and Chuong, alleging that negligent operation of their
watercraft caused their daughter’s death. The defendants moved for summary judgment, claiming that
assumption of the risk applies to jet skiing. The parents appealed, arguing that jet skiing was not a
sport and Rachael never assumed any risk.
Issue: Does assumption of the risk apply to jet skiing?
Excerpts from Judge McAdams’s Decision:
In a sports context, [assumption of the risk] bars liability because the plaintiff is said to have assumed
the particular risks inherent in a sport by choosing to participate. Thus, a court need not ask what risks
a particular plaintiff subjectively knew of and chose to encounter, but instead must evaluate the
fundamental nature of the sport and the defendant’s role in or relationship to that sport.
In baseball, a batter is not supposed to carelessly throw the bat after getting a hit and starting to run to
first base. However, assumption of risk recognizes that vigorous bat deployment is an integral part of
the sport and a risk players assume when they choose to participate. A batter does not have a duty to
another player to avoid carelessly throwing the bat after getting a hit.
Even when a participant’s conduct violates a rule of the game and may subject the violator to internal
sanctions prescribed by the sport itself, imposition of legal liability for such conduct might well alter
fundamentally the nature of the sport by deterring participants from vigorously engaging in activity.
Coparticipants’ limited duty of care is to refrain from intentionally injuring one another or engaging in
conduct that is so reckless as to be totally outside the range of the ordinary activity involved in the
sport.
It appears that an activity falls within the meaning of ‘sport’ if the activity is done for enjoyment or
thrill, requires physical exertion as well as elements of skill, and involves a challenge containing a
potential risk of injury.
As a matter of common knowledge, jet skiing is an active sport involving physical skill and challenges
that pose a significant risk of injury, particularly when it is done—as it often is—together with other
jet skiers in order to add to the exhilaration of the sport by racing, jumping the wakes of the other jet
skis or nearby boats, or in other respects making the sporting activity more challenging and
entertaining. In response to the plaintiff’s complaint that the trial court erroneously assumed that the
litigants were contestants in some sort of consensual competition event and/or spectator sport, [we
conclude] that the doctrine applies equally to competitive and noncompetitive but active sports.
Plaintiffs urge [that] Rachel was merely a passenger on the Polaris and was not actively involved in the
sport. The record supports the conclusion that riding as a passenger on a personal watercraft [is
participating in a sport], because it is done for enjoyment or thrill, requires physical exertion as well as
elements of skill, and involves a challenge containing a potential risk of injury. The vessel is open to
the elements, with no hull or cabin. It is designed for high performance, speed, and quick turning
maneuvers. The thrill of riding the vessel is shared by both the operator and the passenger. Obstacles in
the environment such as spraying water, wakes to be crossed, and other watercraft are part of the thrill
of the sport, both for the operator and the passenger.
The summary judgment is affirmed.
