Barinder Singh Gill at California-based trucking company Jumbo Logistics Paramjit Singh Sandhu, a 45-year-old truck driver, drove up to a medical facility in Sachse, Texas in December 2020 for what should have been a routine drug test. A resident of Texas, Sandhu has worked in the trucking industry for more than two decades. Under federal law, truck drivers are mandated to undergo a drug test. But this time, when Sandhu arrived at a MedPost Urgent Care facility, a nurse refused to administer one unless he removed his “hat” – referring to his dastaar, or turban. Sandhu told Scroll.in he had taken a drug test just six months before this incident and another test at the very same facility in mid-2019, and did not have to remove his turban.
