Minimum Required D-Value for GVM vs ATM
The minimum required D-value for GVM vs ATM is one of the most understood calculations in the truck and trailer industry.
The D-value is calculated using the truck and trailer’s permissible total weight.
D-Value Equation
D-Value = 9.81 x (Tow Vehicle GVM x Trailer ATM) / (Tow Vehicle GVM + Trailer ATM)
If you do the equation, a 12t truck tow an 8t trailer has a D-Value of 47Kn.
