Truck-Mounted Attenuator (TMA) requirement
In New York, TMAs are required by their Standard Specifications in slow-moving work zones and stationary work on high speed highways in travel lanes. In lower speed applications barrier vehicles with TMAs must be used where MUTCD buffer space can’t be provided. TMAs are included in the lump sum bid for maintenance and protection of traffic.
