Many Long Islanders will be returning from the Thanksgiving holiday Sunday, but have to follow strict COVID-19 guidelines as they land in New York.

Despite concerns over coronavirus spreading, over 6 million Americans traveled during this weekend.

Gov. Andrew Cuomo says that everyone returning to the state must get tested three days prior to traveling. They must also quarantine for three days before arrival, and get a test on the fourth day after arriving.

Officials say they're expecting a spike in cases due to the travel. Cuomo says anyone breaking quarantine rules could face fines of up to $10,000.

Health officials say travelers have to be extra cautious because they could test negative now and it would give them a false sense of security.

An AAA spokesperson tells News 12 its projections show that a majority of people who traveled by car were taking shorter trips of less than 50 miles, so expect to see more cars on the road as people come home.

The National Guard is also stationed throughout New York airports to ensure people are following COVID-19 rules.
