The bill enacts new provisions under R.S. 32:387.21, 387.22, and 387.23, which establish special permits for trucks transporting materials in Louisiana. Specifically, it allows for the issuance of per project special overweight permits for trucks carrying earthen materials for government-funded levee projects, with a validity of one year and a fee of $1,000 per project. The bill also sets weight limitations for these trucks, allowing a gross weight of up to 70,000 pounds, while ensuring that municipal or parish ordinances regarding weight limits are not preempted. Additionally, the secretary is authorized to impose penalties for violations of these weight limits and to promulgate necessary rules and regulations.

Furthermore, the bill introduces special permits for trucks hauling raw input materials for concrete and finished concrete products, allowing a ten percent weight variance for a fee of $400 per unit. It also provides for a twelve percent weight variance for single unit dump trucks, with an annual permit fee of $800 per truck. Both types of permits prohibit penalties for exceeding weight limits as long as the excess weight remains within the specified variances, but they do not allow for exceeding posted weight limits on bridges.
