Most Awarded Custom Attenuator Trucks

Royal's TMA Truck Build

The Nation's Safest TMA Truck

ROYAL STANDS BEHIND THE QUALITY OF EVERY TRUCK WE BUILD. Our TMA truck surpasses the standards and certification processes of even the strictest state regulations. Our unique attenuator truck bodies have been engineered to successfully sustain high speed impacts. Other's have tried, but they cannot be replicated! ... Crash attenuators should be used anytime you are restricting the flow of traffic and on job sites that are deemed high hazard such as: nighttime operations, roads with heavy traffic, during the initial phase of a long term project, and when traffic control signs and devices are being set out or picked up.

TMA Truck Ballast

Heavy Duty Steel Flatbed Body

Truck Ballast

The truck ballast is one of the most crucial components of a TMA truck, that unfortunately, some builders ignore entirely. A traffic control truck that is too light can have deadly consequences. Royal's custom engineered center compartments contain a concrete ballast which is installed to achieve a minimum weight of 20,000 lbs. Every Royal TMA Truck meets our TMA manufacturer's recommendations and the requirements of the NCHRP Report 350 and now AASHTO's MASH standards.

TMA Truck On Air Brakes

No Exception

Air Brakes

At Royal we believe so strongly that all TMA Trucks should be built on air brakes. It is unarguably the safest option. Hydraulic brakes can break apart or simply fail during an impact, sending your massive truck rolling into the work zone it's supposed to be protecting. Air brakes also eliminate human error. Imagine being in a panic seeing an oncoming vehicle and trusting you can hit and hold down the brake petal. Air brakes simply lock on impact, keeping your TMA truck within it's roll ahead distance. Our trucks are under 26,000 lbs so you do not need a CDL to drive one.

TMA Truck Bulk Head

Heavy Duty

Bulkhead

In the event of a high speed impact, the bulkhead protects the driver from injury. Each truck has a 54" x 8' wide steel bulkhead with a mesh window and heavy duty stationary rear corner posts. The bulkhead is 3" thick and extends higher than the cab to provide the most protection possible for the driver.

Royal Truck & Equipment Manufacturer of Traffic Control Truck

If you build or modify trucks by installing truck bodies, or related equipment, you must certify them. Failure to certify can result in massive penalties and if you get caught with Joe's TMA truck without it, you're in big trouble! Royal is one of the ONLY TMA Truck producers that can affix a final stage manufactures sticker on an attenuator truck. We're authorized to re-purpose a truck from any other type, into a TMA Truck. This includes performing a FMVSS compliance analysis, a payload and weight distribution analysis among others.

Attenuator Truck Arrow Board

15 or 25 Light

Arrow Board

Each attenuator truck comes with 15 or 25 light arrow board, depending on your state's regulations. We use a vertical telescopic mount which is raised and lowered by hydraulics. The system has a dedicated battery which is charged by the solar panel. The arrow board is operated by a cab-mounted control.

Attenuator Truck Solar Panel

Bulkhead Mounted

Solar Panel

We mount the solar panel on the bulkhead so it's closer to the sun, go figure! The location also prevents operator damage. The solar panel charges the arrow board battery. The battery is a deep cycle marine battery that will charge your arrow board for 20 - 30 days! (If you've gone without sun exposure for that long.)

Attenuator Truck Radar Board & Message Board

Message &

Radar Board

Proven to slow traffic speeds: Royal's radar board is a 3' x 5' full matrix display with GPS and radar overspeed detection. The best part is that live speeds are overlaid on DVR recordings, if you have one. You'll know exactly how fast a vehicle was traveling in the event of an impact. Companies have used speed recordings to show dangerous speeds in their work zones to request police presence to slow travelers. The system has Bluetooth connectivity for custom message selection, programming, and diagnostics.
