Masks are now compulsory on all public transportation in Los Angeles County, for the second time in as many years.

According to experts from the Los Angeles Department of Public Health, the CDC has stated that wearing a mask when using public transit is crucial to limiting the spread of COVID-19.

To prevent the transmission of contagious diseases, travelers in Los Angeles County will once again be compelled to wear face masks while traveling on public transportation or in enclosed transportation hubs such as airports.

Beginning Friday, the Los Angeles County Department of Public Health will enforce a new COVID-19 health order, which will require all people who utilize public transit, including buses, trains, taxis, and ride-sharing services to wear masks. The order is effective immediately.
