Requirements for work or shadow vehicles to have Truck-Mounted Attenuator (TMA)

New Hampshire does not require a truck-mounted attenuator (TMA) to protect workers or work vehicles during lane closure set-ups and removals.
NHDOT has included some TMA requirements in project-specific Traffic Control Plans ( i.e., a signing project on the right of a multi lane highway, a TMA is included in TCP for this mobile operation).
NHDOT Bureau of Traffic utilizes a TMA during pavement marking operations.
