Requirement for Face Masks on Public Transportation Conveyances and at Transportation Hubs
Updated Mar. 23, 2021
Traveling on public transportation increases a person’s risk of getting and spreading COVID-19 by bringing people in close contact with others, often for prolonged periods, and exposing them to frequently touched surfaces. Air travel often requires spending time in security lines and busy airport terminals. Travel by bus, train, and other conveyances used for international, interstate, or intrastate transportation poses similar challenges. Staying 6 feet away from others is often difficult on public transportation conveyances. People may not be able to distance themselves by the recommended minimum of 6 feet from other people seated nearby or from those standing in or passing through the aisles on airplanes, trains, or buses.
Travel contributes to interstate and international spread of the virus that causes COVID-19. Wearing masks that completely cover the mouth and nose reduces the spread of COVID-19. People who never develop symptoms (asymptomatic) or are not yet showing symptoms (pre-symptomatic) might not know that they are infected but can still spread COVID-19 to others. Masks also offer protection to the wearer.
CDC has issued an Order that requires face masks to be worn by all travelers while on public transportation (which includes all passengers and all personnel operating conveyances). People must wear masks that completely cover both the mouth and nose while awaiting, boarding, disembarking, or traveling on airplanes, ships, ferries, trains, subways, buses, taxis, and ride-shares as they are traveling into, within, or out of the United States and U.S. territories. People must also wear masks while at transportation hubs (e.g., airports, bus or ferry terminals, train and subway stations, seaports, U.S. ports of entry, and other locations where people board public transportation in the United States and U.S. territories).
People are not required to wear a mask under the following circumstances:
- while eating, drinking, or taking medication for brief periods of time;
- while communicating for brief periods of time with a person who is hearing impaired when the ability to see the mouth is essential for communication;
- if, on an aircraft, wearing oxygen masks is needed because of loss of cabin pressure or other event affecting aircraft ventilation;
- if unconscious (for reasons other than sleeping), incapacitated, unable to be awakened, or otherwise unable to remove the mask without assistance;
- when necessary to temporarily remove the mask to verify one’s identity such as during Transportation Security Administration (TSA) screening or when asked to do so by the ticket or gate agent or any law enforcement official;
- when experiencing difficulty breathing or shortness of breath or feeling winded, until able to resume normal breathing with the mask; when vomiting until vomiting ceases; or if wearing a mask interferes with necessary medical care such as supplemental oxygen administered via an oxygen mask.
The following categories of people are exempt from the requirement to wear a mask:
- A child under the age of 2 years;
- A person with a disability who cannot wear a mask, or cannot safely wear a mask, because of the disability as defined by the Americans with Disabilities Act (42 U.S.C. 12101 et seq.);
- A person for whom wearing a mask would create a risk to workplace health, safety, or job duty as determined by the relevant workplace safety guidelines or federal regulations.
People on board the following categories of conveyances are exempt from the requirement to wear a mask:
- Private conveyances operated only for personal, non-commercial use;
- Commercial motor vehicles or trucks, if the driver is the only person in the vehicle or truck, or the vehicle or truck is operated by a team who all live in the same household and are the only persons in the vehicle;
- Conveyances operated or chartered by the U.S. Department of Defense (DOD) as long as the operator of the conveyance follows all DOD requirements to prevent spread of COVID-19 that are equivalent to the requirements in CDC’s Order.
Frequently Asked Questions
What is a public transportation conveyance?
A public transportation conveyance is any mode of transportation other than a private vehicle. Types of public transportation conveyances include airplanes, trains, subways, buses, taxis, ride-shares, maritime transportation, trolleys, and cable cars.
Which public transportation conveyances does the order apply to?
The order applies to all public transportation conveyances traveling into the United States (i.e., arriving from a foreign country) or within the United States (including within states or territories or traveling between states or territories). This includes school buses. The Order also applies to all conveyances leaving the United States until they arrive at a foreign destination.
Are masks required on school buses?
Yes, passengers and drivers on school buses must wear a mask, including on buses operated by public and private school systems, subject to the exclusions and exemptions in CDC’s Order. Operators of school buses should refer to the Department of Education’s COVID-19 Handbookpdf iconexternal icon for additional guidance.
Drivers do not need to wear a mask if they are the only person on the bus.
What kind of mask should I wear?
People must wear masks that completely cover the mouth and nose. Masks should fit snugly against the sides of the face. See CDC’s guidance for attributes of masks needed to fulfill the requirements of the Order. For more information about masks, see Your Guide to Masks.
Can I wear a face shield instead of a mask?
Face shields do not fulfill the requirements of the Order. Face shields may be worn in addition to a mask that fulfills the requirements of the Order, but face shields may not be worn instead of a mask. A face shield is effective at protecting the person wearing it from splashes to the face, particularly the eyes, but face shields do not protect others from respiratory droplets exhaled by the wearer. A face shield worn without a mask also does not protect the person wearing it from inhaling respiratory droplets.
What is a transportation hub?
A transportation hub is any location, indoors or outdoors, where people await, board, or disembark public transportation conveyances. These include but are not limited to commercial airports, general aviation airport buildings with commercial flights, bus terminals, all commercial vessel terminals, marinas, train and subway stations, seaports, U.S. ports of entry, and dedicated ride-share pick-up locations.
Which transportation hubs does the order apply to?
The order applies to all transportation hubs in the United States and U.S. territories, except those operated by the U.S. Department of Defense.
Who is an operator of a public transportation conveyance?
A public transportation conveyance operator is any individual (e.g., crew, driver) or organization (e.g., transportation company) causing or authorizing the operation of a conveyance.
What happens if I don’t wear a mask on a public transportation conveyance?
Operators of public transportation conveyances must refuse to board anyone not wearing a mask that completely covers the mouth and nose and require that everyone on board wears a mask for the entire duration of travel. If a passenger refuses to comply, the operator must disembark the person at the earliest safe opportunity.
What happens if I don’t wear a mask in a transportation hub?
Operators of public transportation hubs must use best efforts to make sure that anyone entering the premises is wearing a mask that completely covers the mouth and nose and require that everyone on the premises wears a mask, subject to the exclusions and exemptions in CDC’s Order. If a person refuses to comply, the operator must use best efforts to remove the person from the premises at the earliest safe opportunity.
What if I need to take my mask off during travel or in a transportation hub?
There are some circumstances when taking your mask off would be necessary, including brief periods of time while eating, drinking, or taking medication. Other reasons include medical emergencies, to verify identity during security screenings, or if asked to do so by ticket/gate agents or law enforcement. On a plane, masks should be removed if oxygen masks are needed because of loss of cabin pressure or other event affecting aircraft ventilation.
If you touch your mask while wearing or removing, wash hands with water and soap for 20 seconds or use hand sanitizer.
Do workers at transportation hubs need to wear masks at all times in a work area?
Employees must wear a mask while on the premises of a transportation hub unless they are only person in the work area, such as might occur in private offices, private hangars at airports, or in railroad yards. If another person enters the work area, or the employee leaves the work area and enters another area where others may be located, the employee must wear a mask. If the nature of the work area is such that persons are likely to be located there and are permitted to enter or leave unannounced, then a mask must be worn at all times.
Employees are also exempted from the mask requirement if wearing a mask would create a risk to workplace health, safety, or job duty as determined by the relevant workplace safety guidelines or federal regulations.
Do I need to wear a mask if I have recovered from COVID-19?
Yes, the order requires all travelers to wear a mask, including those who have recovered from COVID-19.
Do I need to wear a mask if I have had a COVID-19 vaccine?
Yes, the order requires all travelers to wear a mask, including those who are fully vaccinated against COVID-19.
What if another person near me refuses to wear a mask?
If you are on a conveyance and a passenger near you refuses to wear a mask, alert personnel working on the conveyance (e.g., crew member, driver, conductor) for assistance. If you are in a transportation hub, notify a staff member or security personnel.
Does CDC’s Order allow removal of a mask while on the premises of a transportation hub for the purpose of smoking or using tobacco products in areas where tobacco use is otherwise allowed?
No. CDC’s Order does not include an exception for tobacco use. Additional information about smoking and COVID-19 may be found on CDC’s website.
Why is CDC making this a requirement now?
Scientific evidence shows that consistent and universal use of masks on public transportation systems and in transportation hubs will protect Americans and help to reduce the spread of COVID-19. Mask use will enable Americans to travel responsibly and as safely as possible when they need to travel during the pandemic.
