Masks are staying on for a while longer for those who ride on any Dallas Area Rapid Transit vehicles.

The Transportation Security Administration issued a security directive extending its face mask requirement for all transportation networks, including public transportation like DART, until Jan. 18 of the upcoming year. This direction from the TSA was previously set to expire Sept. 13.

For DART, this applies at all times to passengers and operators on buses, trains, paratransit vehicles, DART stations, platforms, DART buildings and on-board the Dallas Streetcar, the agency shared in a release. Masks must be worn over the mouth and nose and be Centers for Disease Control and Prevention (CDC) approved.

Face masks and hand sanitizer are available via dispensers on DART buses, light rail vehicles and streetcars.

Those not wearing masks, unless exempted or excluded by CDC guidelines, will not be able to board or will be removed from DART transportation. Refusing to wear a mask could lead to federal penalties, including fines of up to $250 for the first offense or up to $1,500 for repeat offenders, the agency shared.

Customer service is available to respond to passengers concerned with someone not wearing a mask at 214-979-1111 or through the DART Say Something app.
