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.
