Maximum Permit Weight Allowed

Determining maximum weights allowed on axles that are below minimum spacing requirements. Taking the example above where the legal weight on the drivers plus the single axle has been reduced from 27,900 kg to 25,900 kg.

• On a Tandem to a Single Axle combination or a Tandem to Tandem Axle combination you would calculate the maximum weight allowed by multiplying the reduced weight 25,900 x 1.2 = 31,080 kg which would be the maximum weight allowed.
• On a Tridem to a Tandem or a Single Axle you would calculate by multiplying the reduced weight x 1.15 to get the maximum weight allowed.

On the Permit you would enter these combined weights as a single weight. For example, 25,900 would cover legal and 31,080 would cover maximum for the above example and these are the weights that would be entered - 17,900 and 10,000 would not appear on the permit unless the unit was overweight on one set of axles. Then, it would be whichever is greater as it is with all permits.
