New Delhi, Sept. 14 -- Thousands of Sikh truck drivers and operators who form the backbone of the US commerce are feeling threatened over past some days due to tightened scrutiny, following deadly Florida crash.

On August 12, 28-year-old Harjinder Singh, an India-born truck driver, made a U-turn on the Florida Turnpike that allegedly caused a crash that killed three people.

The accident sparked online vitriol denigrating members of the Sikh community, who often covet high-paying trucking jobs that allow Sikh men to wear beards, uncut hair and turbans.

"Lots of drivers are scared right now," reported Los Angeles Times, quoting Sumit Singh.

Singh added that all the community shouldn't be penalised just because of one person.
