TMA Vehicle Dubai – What It Is and Why Your Road Works Project Needs One

A TMA vehicle — Truck Mounted Attenuator vehicle — is the shadow truck that follows directly behind a work crew on a live road, fitted with a crash-absorbing attenuator device at its rear. If an errant vehicle strikes the work zone from behind, the TMA vehicle takes the hit instead of the workers. HMJ Contracting provides TMA vehicle rental across Dubai with trained operators.

What Makes a TMA Vehicle Different from a Normal Truck?

A TMA vehicle is a standard heavy truck — typically 7.5 tonnes or above — with a specialised crash attenuator mounted on its rear. The attenuator is designed to crush progressively on impact, absorbing and dissipating the kinetic energy of a striking vehicle over a controlled distance. The truck itself acts as ballast, preventing the TMA from being pushed forward into the work crew on impact. This combination of energy absorption and mass is what makes the TMA vehicle effective as a last line of defence.

TMA Vehicle Specifications for Dubai Roads

• Urban roads (60–80 km/h) — standard TMA vehicle with appropriate impact rating
• Highway and expressway roads (80–120 km/h) — highway-rated TMA vehicle with higher energy absorption capacity
• All TMA vehicles used by HMJ are RTA-approved for Dubai road classifications
• Each vehicle is inspected before every deployment to confirm the attenuator is operational

TMA Vehicle Operation

The TMA vehicle is operated by a trained TMA driver who maintains the correct following distance behind the work crew, monitors approaching traffic continuously, and positions the vehicle to maximise protection. On mobile works, the TMA vehicle moves with the crew. On stationary works, it parks at the designated position behind the work zone. See our guide on how truck mounted attenuators work.
