FAQ

WHAT IS A TMA TRUCK?

A TMA, or truck mounted attenuator truck, is placed strategically in a highway work zone to protect workers from errant vehicles in oncoming traffic. This truck has an impact attenuator, or crash cushion, that absorbs the kinetic energy of the colliding vehicle.

DO I NEED A CDL TO DRIVE A TMA TRUCK?

At Royal Truck & Equipment, we weight our trucks less than 26,000 lbs. So you don’t need a CDL to drive one, in most states. Click here to see the exception!

WHAT IS ROLL AHEAD DISTANCE?

Roll ahead distance, or RAD, is the distance a TMA will be displaced in the event of an impact. This is extremely important to know so your attenuator truck does not roll into your work zone. Many states require a specific distance between the truck and workers. Learn more here.

WHAT IS THE TRUCK MOUNTED GENERATOR? AND IS IT WORTH IT?

Yes it is! Our truck mounted generator runs the safety lights and attenuator on your TMA truck so that you don’t have to leave your engine running! There is huge cost savings here as for as fuel costs and wear and tear on your truck. Check it out!

WHAT IS VIRTUAL REALITY TRAINING?

Virtual Reality Training is the future of work zone safety, and it’s not just for the highway construction industry! VR training allows you to step into a virtual version of a dangerous work procedure. You retain more information while you practice high risks tasks in a safe, simulated environment. Learn more here.
