Bus driver Jing Dong allegedly killed five people last week, including two children, when he plowed into other vehicles on I-95 in Virginia. Not only was the naturalized U.S. citizen from China unable to speak English, but he also refused an English proficiency test after the crash. So, what was he doing on our roads?Two more questions: How did Dong gain American citizenship without being able to speak the language, and how did he get a commercial driver’s license? While neither should have been possible, the latter is being investigated by the Department of Transportation, which has subpoenaed the state of New York for information on his CDL, training, and driving school.Dong’s crash is just the latest in a string of deadly incidents allegedly caused by immigrants given CDLs without being able to speak English. Just last year, three major incidents generated headlines and caused the Trump administration to crack down on such licenses being given to non-English speakers. Indian illegal immigrant Harjinder Singh allegedly killed three while making an unauthorized U-turn in his semi-truck; Indian illegal immigrant Jashanpreet Singh allegedly killed another three when he slammed his semi-truck into stopped traffic; and Chinese illegal immigrant Yisong Huang allegedly rear-ended a tractor-trailer with his bus while distracted by a phone video, killing one.
