The passengers in your vehicle are over 15 years old. Who is responsible for ensuring they wear their seatbelts?

If the passengers in your vehicle are over the age of 15, it is the responsibility of the passengers themselves to ensure they are wearing their seatbelts. In New Zealand, the law stipulates that passengers are responsible for buckling up, while the driver is also responsible for ensuring that all passengers in the vehicle comply with seatbelt regulations.
