Everything the Trump administration has done this year to strengthen and enforce the standards for truck drivers and the schools that train them after several deadly crashes may cause problems for some companies if immigrants continue to flee the profession rather than deal with the harassment and scrutiny.

The Transportation Department's new restrictions that would severely limit which immigrants can get commercial driver's licenses to drive a semitrailer truck or bus have been put on hold by a federal appeals court.

The nationwide audit of these licenses began after a fatal U-turn crash in Florida that killed two people caused by a truck driver who officials said was in the country illegally. Transportation Secretary Sean Duffy said also threatened to revoke $160 million in federal funding for California because investigators found that one in four of the 145 commercial drivers licenses for non-citizens issued since June should have never been issued.

Transportation Secretary Sean Duffy says California, Washington and New Mexico could lose millions of dollars of federal funding if they continue failing to enforce English language requirements for truckers. An investigation launched after a deadly Florida crash involving a foreign truck driver who made an illegal U-turn earlier this month found what Duffy called significant failures in the way all three states are enforcing rules that took effect in June.

Several thousand workers at CSX will soon get one of the things that pushed the railroad industry to the brink of a strike last fall: paid sick time. Florida-based CSX announced the deal with two of its 12 unions.
