Requirement for Face Masks on Public Transportation Conveyances and at Transportation Hubs

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.

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). The Order also applies to all conveyances leaving the United States until they arrive at a foreign destination.

If a conveyance has outdoor areas (such as on a ferry or an open-air trolley or bus), wearing a mask is not required while outdoors unless otherwise required by the operator, federal, state, tribal, territorial, or local government.

Subject to how other federal partners and state and local entities define “outdoors,” CDC understands “outdoors” to refer to any open-air area. Examples of outdoor areas of conveyances are the uncovered top decks of buses and open deck areas of ferries or other vessels. Examples of outdoor areas of transportation hubs include surface parking lots and partially enclosed parking garages, passenger pick-up/drop-off areas, railway platforms, piers, open hangars, and airport runways.

No, CDC does not require people to wear masks on buses or vans operated by public or private K-12 school systems or early care and education/child care (ECE) programs. At their discretion, school systems and ECE programs may choose to require that people wear masks on buses or vans.

People must wear masks that completely cover the mouth and nose. Masks should fit snugly against the sides of the face. See attributes of masks needed to fulfill the requirements of the Order. For more information about masks, see Types of Masks and Respirators.

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.

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, train and subway stations, seaports, U.S. ports of entry, and dedicated ride-share pick-up locations.

The Order applies to all indoor areas of all transportation hubs in the United States and U.S. territories, except those operated by the U.S. military. Unless otherwise required by the operator, federal, state, tribal, territorial, or local government, people are not required to wear a mask when located in outdoor areas of a transportation hub.

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. The term “personnel operating conveyances” is used in these FAQs to refer specifically to individuals (e.g., crew members, drivers, conductors) on a conveyance for the purpose of operating it.

On conveyances with no outdoor spaces, operators of public transportation conveyances must refuse to board anyone not wearing a mask that completely covers the mouth and nose. On conveyances with outdoor areas, operators must refuse to allow entry to indoor areas to anyone not wearing a mask. Operators must also require that everyone on board (or in an indoor area of the conveyance, as applicable) wears a mask for the entire duration of travel, subject to the exclusions and exemptions in CDC’s Order. If a passenger refuses to comply, the operator must disembark the person at the earliest safe opportunity (or relocate the passenger to an outdoor area of the conveyance, if feasible). People who refuse to wear a mask may be subject to a civil penalty.

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.

Personnel operating passenger-carrying conveyances (e.g., crew members, drivers, conductors) covered by the Order, must wear a mask while indoors on the conveyance, unless the person operating the conveyance is the only person on the conveyance, or the conveyance is operated by a team who all live in the same household and are the only people on the conveyance.

If the conveyance has outdoor areas, wearing a mask is not required outdoors. Operators of conveyances (i.e., employers), at their discretion, may require personnel operating conveyances to wear masks in outdoor areas of the conveyance.

Personnel operating conveyances 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.

Workers, including federal employees, must wear a mask while indoors on the premises of a transportation hub unless they are the 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 worker leaves the work area and enters another area where others may be located, the worker must wear a mask. If the nature of the work area is such that other workers are likely to be located there and are permitted to enter or leave unannounced, then a mask must be worn at all times.

CDC does not require that workers wear a mask in outdoor areas of a transportation hub. Operators of transportation hubs (i.e., employers), at their discretion, may require employees to wear masks in outdoor areas.

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.

Yes, the Order requires all people to wear a mask, including those who are up to date with their COVID-19 vaccines, if they are located indoors on a conveyance or indoors at a transportation hub.

Yes, the Order requires all people to wear a mask, including those who are fully vaccinated against COVID-19, if they are located indoors on a conveyance or indoors at a transportation hub.

If you are in an indoor area of a conveyance and a passenger near you refuses to wear a mask, alert someone working on the conveyance (e.g., crew member, driver, conductor) for assistance. If you are in an indoor area of a transportation hub, notify a staff member or security personnel.

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.

Public transportation conveyances and transportation hubs are locations where large numbers of people may gather, and physical distancing can be difficult. Furthermore, many people need to take public transportation for their livelihoods. Personnel operating the conveyance and passengers (including young children) might be unvaccinated, and some on board might be at increased risk of severe illness (including some who might not be protected by vaccination because of weakened immune systems). Such people may not have the option to disembark or relocate to another area of the conveyance, such as on an airplane during flight or a bus or train while it is in motion. Transportation hubs are also places where people depart to different geographic locations, both across the United States and around the world. Therefore, an exposure in a transportation hub can have consequences to many destination communities if people become infected after they travel.

CDC does not require people to wear a mask in outdoor areas of conveyances and transportation hubs because of the lower risk of transmission outdoors. However, in areas with a high COVID-19 Community Level, people might choose to wear a mask outdoors when in sustained close contact with other people, particularly if they or someone they live with has a weakened immune system or is at increased risk for severe disease.

Correct and consistent use of masks in indoor areas on public transportation conveyances and indoor areas of transportation hubs will protect travelers and workers, enable safe and responsible travel during the pandemic, and help to reduce the spread of COVID-19.

Yes, the mask order applies to all persons traveling on commercial maritime conveyances into, within, or out of the United States and to all persons at U.S. seaports, when located in indoor areas. The term commercial maritime conveyance means all forms of commercial maritime vessels, including but not limited to cargo ships, fishing vessels, research vessels, self-propelled barges, and all forms of passenger carrying vessels including ferries, river cruise ships, and those chartered for fishing trips, unless otherwise exempted.

For cruise ship operators opting into CDC’s COVID-19 Program for Cruise Ships, CDC will continue to exercise enforcement discretion regarding the requirements of this Order, applicable to operators of, and crew and passengers on board, cruise ships. Cruise ships that have chosen not to participate remain subject to the requirements of the Order.

Only the following maritime conveyances are exempted:

• Private maritime conveyances operated solely for personal, non-commercial use (e.g., personal watercraft),
• When the operator is the sole occupant on board the maritime conveyance,
• Mobile offshore drilling units and platforms, to include floating and fixed Outer Continental Shelf facilities as defined in 33 CFR 140.10, and
• Certain maritime conveyances excluded from the definition of vessels under 42 CFR 70.1:
  • Fishing boats including those used for shell-fishing^*;
  • Tugs which operate only locally in specific harbors and adjacent waters^†;
  • Barges without means of self-propulsion;
  • Construction-equipment boats and dredges; and
  • Sand and gravel dredging and handling boats.^* Fishing vessels, fish processing vessels, and fish tender vessels as defined under 46 U.S.C § 2101 do not fall under this exemption — including shell-fishing vessels. A “fishing boat” is an auxiliary craft as defined under 46 U.S.C § 4502(k) carried on board a fishing vessel.^† Tugs which operate only locally in specific harbors and adjacent waters means tug vessels operating exclusively within a worksite and that have been issued a worksite exemption by the U.S. Coast Guard.

Please note that the operators of these maritime conveyances and other persons on board must observe CDC’s mask order while in indoor areas at the seaport.

The term seaport means any port of entry or any other place where persons await, board, or disembark all forms of maritime commercial conveyances (e.g., a marina or dock). Wearing a mask is required in all indoor areas of a seaport.

No, this exemption does not exempt mariners from the mask order simply by virtue of working on a non-passenger related commercial maritime conveyance. To be exempt, the mariner would need to be performing a duty that would, if a mask were worn, create a risk to workplace health, safety, or job duty as determined by the relevant workplace safety guidelines or federal regulations. The exemption only applies while performing that duty.

If the vessel is operated by a team who all live on the vessel and are the only people on the vessel, mariners on commercial vessels are not required to wear masks and should be guided by CDC’s Interim Guidance for Ships on Managing Suspected or Confirmed Cases of Coronavirus Disease 2019 (COVID-19). Per the Interim Guidance, it is recommended that crew wear masks when outside of their single occupancy cabin unless work duties prevent their safe use or wearing a mask may interfere with use of personal protective equipment required due to worksite hazards. Mariners would not be expected to wear a mask while they are alone and are eating, sleeping, or resting. Masks are not required outdoors.

Additionally, mariners must wear masks in indoor areas when other people (e.g., visitors, pilots, inspectors) join the ship for any period of time and when mariners disembark the ship when located in indoor areas of a seaport.

While the Order does not apply to personal maritime conveyances, the mask order applies to all persons in indoor areas on board if a personal maritime conveyance is used for a commercial purpose, such as for a chartered fishing trip. Operators of such conveyances do not need to wear a mask if they are the only person on board.
