When driving on the road, if you see vehicles approaching with orange and purple warning lights, how should you respond?

The driving theory and traffic rules in New Zealand are designed to ensure the safety of all road users. Vehicles approaching with specific colored warning lights, such as orange and purple, typically indicate a particular emergency or special situation. Although the official traffic rules in New Zealand do not specifically mention the exact meanings of orange and purple warning lights, it is crucial to follow the principles of yielding and reducing speed, especially when emergency vehicles, such as ambulances, police cars, or fire trucks, are present.
