What is the maximum length that a drawbar should not exceed when coupling a vehicle?

The maximum length that a drawbar should not exceed when coupling a vehicle is indeed 5 metres. This specification is in place to ensure safe and controlled handling of the vehicle combination. A drawbar that is too long can introduce significant handling issues, such as increased sway and reduced control, especially during turns and abrupt maneuvers.

The 5-metre limit is designed to maintain a balance between maneuverability and stability, ensuring that the connected vehicles can navigate safely without compromising their operational capabilities. Adhering to this standard minimizes the risk of accidents and promotes safer road conditions.

The other lengths provided, such as 2.5 metres, 7.5 metres, and 10 metres, either do not meet the operational safety standards or compromise vehicle control. A drawbar longer than the safe limit could lead to complications, particularly in tight spaces and during emergency situations where swift responses are necessary.
