Cars heading to Austin-Bergstrom International Airport will see random, voluntary inspections Monday.
The searches are part of an increase in security at the airport.
It's a joint operation between the U.S. Department of Homeland Security, Austin Police, and airport security.
The enhancements are not a reponse to specific threats, and the security level has not changed.
Officials say the searches are voluntary and drivers can opt out if they want.
