What looks like a truck on the shoulder is actually an important layer of work zone protection.
TMA trucks, also known as truck-mounted attenuators, are used in traffic control setups to help create a buffer between moving traffic and crews working near the roadway. They are designed to help absorb impact and protect workers when the unexpected happens.
For drivers, the message is simple: slow down, move over when safe, and give traffic control crews the space they need.
