Trump has signed executive orders related to immigration, including one that requires English proficiency for commercial vehicle drivers such as truckers.

This requirement already exists, but Trump said it "hasn't been applied in years," making roads less safe.

The decree reinforces an existing federal law requiring English language proficiency as a mandatory requirement for commercial vehicle drivers.

In a decree issued on Monday evening, Trump claims that "the requirement has not been applied for years, and America's roads have become less safe."

"My Administration will enforce the law to protect the safety of American truckers, drivers, passengers, and others, including by upholding the safety enforcement regulations that ensure that anyone behind the wheel of a commercial vehicle is properly qualified and proficient in our national language, English," the order states.

White House Press Secretary Carolyn Leavitt said, "There's a lot of communications problem between truckers on the road," which is "a public safety risk."

"We're going to ensure that our truckers, who are the backbone of our economy, are all able to speak English," Leavitt said. "That's a very common sense policy in the United States of America."

The Trump administration has not announced how the order will be applied.
