LAC 73:I.713. Permit Axle Weight Distribution

A. The law requires reasonable distribution of axle weight on tandem, tridum, and quadrum axle groups. If a tandem, tridum, or quadrum axle group is permitted for a weight which is less than or equal to the legal axle weight, then the axle must comply with the legal axle weight distribution. If the axle group is permitted for a weight which exceeds the legal axle weight, then the axle must comply with the following. 1. Tandem axles on vehicles with permits are properly distributed if neither of the individual axles carries more than 60 percent or less than 40 percent of the total tandem weight shown on the permit. 2. Tridum axles on vehicles with permits are properly distributed if none of the individual axles carries more than 40 percent or less than 25 percent of the total tridum weight shown on the permit. 3. Quadrum axles on vehicles with permits are properly distributed if none of the individual axles carries more than 30 percent or less than 20 percent of the total quadrum weight shown on the permit.
