Final answer:
Irresponsible ATV riding includes reckless behavior such as high-speed riding in populated areas, performing dangerous stunts, or neglecting to use safety gear.
Step-by-step explanation:
An example of irresponsible ATV riding would be operating the ATV at high speeds in crowded areas, attempting dangerous stunts, or not wearing the proper safety equipment. Similar to how the surfing teens in the example are taking unnecessary risks by surfing too close to each other, ATV riders likewise increase their chances of accidents and injuries when they do not follow safety protocols or engage in reckless behavior. Recognizing hazardous situations and avoiding them is crucial for responsible ATV riding and ensures the safety of both the rider and others around them.
