Only limited overweight permits will be issued for the movement of non-divisible loads in the area of the state that is under spring load restrictions. The overweight permit limitations are as follows:
* The weight per axle may not exceed that allowed by the South Dakota Spring Load Restriction Map or Spring Load Restriction Reports;
* The maximum weight per axle shall be limited to the smallest of 20,000 pounds per axle or 450 pounds per inch width of tire; and
* The weight may not exceed that allowed by the South Dakota Bridge Weight Limit Map or other overweight permit issuance criteria provided by the department of transportation.
The effective date of the load restrictions is determined by weather and road conditions. Normal overweight permits will continue to be issued in portions of the state that are not under spring load restrictions.
A Spring Load Restriction Report is usually issued in advance of any major load restriction change. This report is issued for guidance only and does not take precedence over load restriction signs in place.
