GREEN OVERWEIGHT CHART


Maximum Allowable Weight Distribution for Annual Overweight
Permits on GREEN coded routes of the Route Capacity Map.
Higher axle weight limits for tandem, tridem and quad axles may be allowed if the axle spacing’s are larger.
See chart on next page for axle spacing’s and the allowed weight.

Maximum allowable weight is based on the distance in feet between the first and last axle of any group or groups of consecutive axles.

To find the weight allowed for the vehicle combination, use the number of axles and exle spacings from the number 2 axle to the last axle of the combination, add the weight for the steering axle (approximately 12,000 lbs) to this weight, to acquire the Total Gross Weight Allowed.

To find the weight allowed for self propelled vehicles, use the number of axles and axle spacings from the number 1 axle to the last axle of the combination. If axles have less than 4 tires per axle, see chart above for weights allowed.

Check the weight allowed for every internal group or groups of axles as well as total Gross Weight. At times the sum of the axle weights may be less than the Total Gross Weight Allowed. Must use most restrictive weights.

If the vehicle combination exceeds the weight allowed on any group or groups of axles, or Total Gross Weight Allowed by this chart and the route capacity map, the vehicle must operate on a single trip permit if approved.
