Tallahassee, Oct. 26 -- A Punjab-origin truck driver, who is charged with killing three people in a deadly crash in Florida in August, had failed a commercial driver's licence (CDL) test 10 times in the span of two months in 2023 in Washington state, before he was ultimately issued a licence, according to a senior official in the Florida Attorney General's Office. Florida is using the case of Harjinder Singh, who is accused of being in the country illegally, to urge the nation's highest court to permanently bar some states from issuing commercial driver's licences to people who are not US citizens or lawful permanent residents. Florida's investigation of Harjinder Singh has revealed that the trucker failed a written test to receive a CDL in Washington state 10 times between March 10, 2023, and April 5, 2023, a senior official for Florida Attorney General James Uthmeier who was briefed on the investigation said. Singh lived in California and was originally issued a CDL in Washington before California also issued him one. He was carrying a valid California CDL at the time of the crash, according to court filings. In California, all commercial truck drivers must pass a written test but may be allowed to skip the driving test if they have an out-of-state licence with equivalent classification. Singh is accused of attempting an illegal U-turn from the northbound lanes of Florida's Turnpike near Fort Pierce on August 12. A minivan that was behind Singh's big rig couldn't stop and crashed into the truck, killing its driver and two passengers. Former Rajya Sabha member Tarlochan Singh has written to the US envoy in India, urging the United States to stand by the Sikh drivers' community in the country, saying many of them are allegedly facing suspicion in the wake of a recent semi-truck crash in California. Jashanpreet Singh, a 21-year-old Punjab-origin truck driver, has been accused of causing the crash that left three people dead and several others injured. He allegedly rammed his truck into slow-moving traffic in Southern California on Tuesday, Fox News reported on Wednesday. In his letter dated October 25 to US envoy Sergio Gor, Singh said, "I want to bring to your kind notice and through you, of the USA government that a recent unfortunate road accident by a Sikh driver in California is creating fear among the Sikh truckers in the USA". He attributed this anxiety to the "aggressive publicity" in the media surrounding the incident. The former MP emphasised, "I am not seeking any pardon for the Sikh driver, who should face the court." However, he noted that Jashanpreet's family in Punjab claims he is a baptised Sikh who has vowed not to consume drugs or alcohol. Singh also wrote to India's ambassador to the US, Vinay Mohan Kwatra, seeking support for the well-being of other Sikh drivers in America. In the letter, he mentioned that the publicity of the case has cast a "shadow over the Sikh community", which has "successfully carved out an important position in the US economy". Sikh drivers, especially on the long routes, have now become "an indispensable component of America's supply chain," he mentioned in his letter. "There is already panic among a large number of Indian youths in America due to the new stringent immigrant rules," Singh added in the letter, dated October 25....
