All truckers and pass drivers will have to take their commercial driver’s license tests in English as the Trump administration expands its aggressive campaign to improve safety in the industry and get unqualified drivers off the road. Transportation Secretary Sean Duffy announced the latest effort Friday to ensure that drivers understand English well enough to read road signs and communicate with law enforcement officers. Earlier this week, the Transportation Department said 557 driving schools should close because they failed to meet basic safety standards. And the department has been aggressively going after states that handed out commercial driver’s licenses to immigrants who shouldn’t have qualified for them ever since a fatal crash in August.
