What is required when carrying a passenger under 18 on a snowmobile?

When carrying a passenger under the age of 18 on a snowmobile, it is required that the passenger must wear a helmet. This requirement is crucial for ensuring the safety of young passengers, as helmets provide protection from head injuries in the event of an accident or fall. Wearing a helmet while snowmobiling is part of broader safety regulations aimed at minimizing risks associated with this recreational activity.

In this context, options suggesting that nothing additional is required, or that the passenger must simply be seated, do not meet the necessary safety measures mandated by law. The need for a helmet specifically underscores the heightened vulnerability of younger passengers, recognizing their unique safety needs compared to adults. The mention of a passageway sign does not pertain to the safety measures required for carrying passengers and is not relevant to the specific requirements laid out for snowmobiling with young riders.
