COVID-19: Transportation Response Center
All of the signs and signals documented here are in use in the United States.
Most of the sign and signal options discussed in this document are available in existing U.S. MUTCD guidance, and specific configurations and uses may be available through the FHWA MUTCD experimentation process. Sign, signals and markings standards vary by state and may have changed since the time of publication, and should be checked during the design process.

Regulatory signs include those used to communicate required or prohibited movements.
Include turn restrictions on overhead signs or signal mast arms, particularly for movements that are not adjacent to the curb or a median on which a sign can be placed.

Flashing beacons can be used to enhance overhead and other regulatory signage, indicating to drivers and other users when the transit lane is in force.
Flashing indications on signs may be used to alert street users during times of day when part-time transit lanes are in effect.
Overhead signs above transit lanes and transitways alert drivers and other street users by placing critical information about lane use in a prominent location.
If used on transit lanes, overhead signage should include information about permitted vehicles, time-of-day restrictions, and permitted turns.
Regulatory signage, such as turn restriction signage, can be placed overhead, directly above the movement it is regulating.
Dynamic signs can be used to alert other street users of approaching transit vehicles, and to regulate turns and other movements that are prohibited when transit vehicles are approaching.
Include dynamic elements on overhead signage.
Dynamic signs can be lit during times of day when part-time transit lanes are in effect.
Transit signal heads clarify that a movement or phase is exclusive to transit.
Traditionally used on rail lines, transit-specific signal heads may be used with buses as well.
Transit signals may be used when transit lanes or transit vehicles in mixed-traffic lanes have exclusive phases, including on transit lanes, transitways, or when a signal is used to give the transit vehicle a queue jump in mixed-traffic lanes.
