Welcome to the Truck Trailer Manufacturers Association!
For over 75 years the Truck Trailer Manufacturers Association (TTMA) has been here to assist North America's trailer manufacturers
TTMA is an international trade association whose current membership produces more than 90% of the truck trailers built in North America. Our Associate Members include more than 100 global material and component suppliers who keep those lines moving. Our efforts engage policies and regulations that play a role in assuring the timely, smooth flow of material to keep production moving forward or that affect the cost of production.
