Retarder
Device used to assist brakes in slowing the vehicle. The most common type of retarder on over-the-road trucks manipulates the engine's valves to create engine drag. (This type is commonly referred to as "Jake Brake" because the predominant manufacturer is Jacobs Vehicle Equipment Co.) Other types of retarders include exhaust retarders, transmission-mounted hydraulic retarders and axle-mounted electromagnetic retarders.
RPM (Revolutions Per Minute)

Doubles (Twins, Twin Trailers)
Combination of a tractor and two semitrailers connected in tandem by a converter dolly. (see Converter Dolly; Pintle Hook)
