The correct answer is: 4 meters
Explanation:
In New Zealand, when your vehicle is towing another vehicle, the maximum distance allowed between the two vehicles is 4 meters. This regulation exists primarily to ensure safe operation, preventing instability caused by excessive towing distance, and ensuring that other road users can clearly see the connection between the two vehicles. Maintaining an appropriate distance reduces the risk of accidents in emergency situations, enhances stability while towing, and promotes safe driving on the road.
