New Indiana CDL requirementsThe backstory:House Enrolled Act 1200, now state law, adds new English proficiency requirements for commercial drivers and requires CDL applicants to prove they can communicate effectively, understand traffic signs and signals, respond to law enforcement and complete required records. The law also requires commercial drivers to take their knowledge and skills exams in English or American Sign Language. One of those crashes involved an Amish family killed in northeastern Indiana by a truck driver holding a Pennsylvania CDL, Rokita said. "A company can’t knowingly hire someone if they know that person’s an illegal alien with a bad CDL," Rokita said. "The biggest issue was the people that could not speak English," Orosz said.
