What is the maximum distance allowed between two vehicles being towed?

The correct choice is based on legal driving regulations regarding the towing of vehicles. The maximum distance allowed between two vehicles being towed is 3.5 meters. This distance is prescribed to ensure safety and control during towing operations. Maintaining a distance within this limit helps to prevent excessive sway and instability, which can lead to accidents or loss of control over the towed vehicle.

Distances greater than 3.5 meters could result in a lack of control and increase the risk of collision or an accident if the towing vehicle were to brake suddenly. Therefore, adhering to this maximum distance is crucial for road safety and compliance with traffic regulations.
