A U.S. federal appeals court has halted the implementation of new regulations from the Department of Transportation (DOT), aimed at limiting the ability of migrants to secure commercial driver’s licenses.

The decision was handed down by the U.S. Court of Appeals for the D.C. Circuit, which found that DOT Secretary Sean Duffy’s department failed to adhere to the required procedures when formulating the rule. The court also highlighted the absence of a “satisfactory explanation” demonstrating how the rule would enhance safety, as reported by the Associated Press.

According to the report, the regulation would have permitted migrants holding specific types of visas—namely H-2a, H-2b, or E-2 visas—to obtain commercial driver’s licenses. This change was anticipated to impact around 10,000 migrants who qualify under these visa categories.

The Associated Press further mentioned that these proposed DOT regulations will not be applied retroactively.

Under the rules, migrants “who hold three specific classes of visas” would be allowed to obtain commercial driver’s licenses. Roughly 10,000 migrants, who have H-2a, H-2b, or E-2 visas, along with their commercial driver’s licenses, would “qualify for them,” according to the outlet.

The outlet noted that the new rules from the DOT “won’t be enforced retroactively.”

The DOT’s new rules come after Harjinder Singh, an illegal alien from India and semi-truck driver, allegedly made an illegal U-turn in Florida in August. As a result of the illegal U-turn, three people were left dead.
