TMA vs Crash Cushion: What Is the Difference?

Truck Mounted Attenuators (TMAs) and crash cushions are both impact-protection systems, but they are used in different ways on road projects.

TMA: Mobile Protection

A TMA is mounted on the rear of a heavy vehicle and is commonly used as mobile or shadow protection behind road crews, maintenance teams and moving operations.

Crash Cushion: Fixed Hazard Protection

A crash cushion is positioned in front of an exposed fixed hazard such as a barrier end, work-zone obstacle or other rigid roadside feature.

See our main Crash Cushion Dubai service page.

Key Differences

• TMA: mounted on a vehicle and can move with the operation.
• Crash cushion: normally protects a specific fixed location.
• TMA: commonly protects workers and mobile work zones from rear impacts.
• Crash cushion: commonly shields exposed hazards and barrier terminals.

Can a Project Need Both?

Yes. A road works project may use a TMA for crew protection while also using crash cushions at exposed fixed points. The approved traffic-management arrangement and site risk determine what is required.

Choosing the Right System

Selection should consider road speed, work activity, hazard type, available space, project duration and the approved traffic-management plan.
