In the United States, the minimum age to operate an ATV varies from 14 to 18 years old. Some states require individuals under the age of 18 to wear a helmet and eye protection and take an approved safety training course.
In some states, the minimum age may vary depending on the size or horsepower of the ATV. For example, some states may set a higher minimum age for ATVs with engines over a certain size or horsepower.
It's important to note that the minimum age to operate an ATV may also be influenced by other factors, such as local regulations, insurance policies, and the specific rules of ATV rental companies. It is always best to consult with local authorities and check with the ATV rental company for specific requirements in your area.
