Texas Department of Public Safety troopers on Saturday will begin screening airport passengers arriving in the state from New York, New Jersey, Connecticut and New Orleans, and they plan to conduct random checks afterward to ensure they are quarantining.

The enforcement measures follow Gov. Greg Abbott’s order earlier this week that people flying from those four locations must self-quarantine for 14 days. If their stay in Texas is shorter than that, they must quarantine the entire time.

The troopers will screen passengers arriving from those four locations and require them to fill out a form with identifying information, according to a news release from the agency. They'll be asked to provide their name, date of birth, flight information, driver license or passport number, telephone number, home address and the location where they will be quarantining.

“As part of the department’s efforts to ensure compliance with the Governor’s Executive Order, DPS Special Agents will conduct unannounced visits at the quarantine locations listed on the forms completed by travelers,” the agency said.

Violators could face a fine of up to $1,000 and up to 180 days in jail.

The order, which only applies to those traveling by air, takes effect noon Saturday.

This is a developing story and will be updated.
