What is the maximum permissible trailer weight as a percentage of the tow vehicle weight?

The maximum permissible trailer weight as a percentage of the tow vehicle weight is commonly accepted to be 50%. This means that when calculating how much weight a trailer can legally be towed, the weight of the trailer should not exceed half of the weight of the towing vehicle. This guideline is in place to ensure safe towing practices, as exceeding this ratio can compromise the vehicle's stability, braking capacity, and overall handling, increasing the risk of accidents on the road.

Factors that influence this percentage include the design and capabilities of the towing vehicle, the distribution of weight within the trailer, and terrain conditions. While some vehicles may be capable of towing more than 50%, adhering to this guideline helps prevent towing mishaps and ensures compliance with safety regulations.
