Monster Truck MUDD RII ( Remote Ignition Interrupter)

 

R.I.I. stands for, Remote Ignition Interrupter. This unit is one of the biggest safety devices in a monster truck and actualy contains 2 parts. First is a specialized radio receiver mounted in the truck. The second part is a hand held transmitter that is held by a track official. The transmitter looks like a walkie talkie but instead of talking on it, it broadcasts a special signal when the "talk" button is pushed that will shut down the truck in the event of a problem such as the truck veer off the track and/or the driver become incapacitated. The R.I.I. will only shut off the engine and all of its electronics. Everytime a truck goes out to preform the R.I.I. is tested to make sure it is working properly.
