Determiningthe maximum permissible load
Thefollowingsteps havebeen developed asrequired of all manufacturers underTitle 49,Code ofU.S.FederalRegulations,Part575, pur‐suanttothe "NationalTraffic and MotorVehicleSafetyAct of1966".
#Step 1:locatethestatement "The combinedweight of occupants and load should neverexceed XXXkgor XXX lbs." ("The combinedweight of occupants and load should neverexceed XXXkgor XXX lbs.") onyourvehicle'sTireand Loading Information placard.
#Step 2:determinethe combinedweight ofthe driver and passengersthat will be travel‐ing inyourvehicle.
#Step 3:subtractthe combinedweight ofthedriver and passengers from XXXkgorXXX lbs.
#Step 4:theresultingfigure equalsthe per‐missible cargo and luggage load capacity.Forexample: If "XXX" equals1400 lbs andtherearefiveoccupants inyourvehicle with aweight of150 lbs each,the maximum cargoand luggage load capacity is 650 lbs (1400 -750 (5 x150) = 650 lbs).
#Step 5:determinethe combinedweight ofluggage and loadthatthevehicle will be car‐rying.For safetyreasons,thisweight may notsafelyexceedtheavailable cargo and lug‐gageload capacity calculated instep 4.

Even ifyou havecalculatedthetotal load care‐fully,you shouldstill make surethatthe maxi‐mum permissible gross mass andthe maximumpermissible axle load ofyourvehicle are notexceeded. Details can befound onthevehicleidentification plate.
#Haveyour loadedvehicle – including driver,occupants and load –weighed on avehicleweighbridge.The measuredvalues may notexceedthemaximum permissiblevaluesstated onthevehicle identification plate.
