The US Centers for Disease Control and Prevention issued an order late Friday requiring masks in interstate transportation and at transit hubs, including airplanes, mass transit, taxis and trains, starting late Monday.

The CDC said the mask mandate, effective from Feb. 1 at 11:59 p.m. EST, also covers ride-share vehicles and subways and makes not wearing a mask as instructed a violation of federal law. The order does not apply to private cars or commercial trucks being driven by a sole operator.The CDC directive follows an order from President Joe Biden on Jan. 21 directing agencies to "immediately take action" to require masks on transportation and at transit hubs.

The obligation does not apply to toddlers aged two or below, nor does it apply to people using commercial trucks and military transportation, according to NBC News.

If eating or drinking on public transportation, as well, the passengers on public transportation may shortly remove their masks.

Mask-wearing has also been made mandatory on all federal properties.
