I cannot find the proper noun for the guy who is accompanying the truck driver throughout the journey?Is he considered a truck driver? His responsibility is to drive the truck when the main driver is tired or sleepy.

Also, is there a website or a book that has collection of such jargon?

    "Team drivers" are both CDL drivers. In electronic log books, one is active (driving) and the other inactive/sleep mode. No doubt, truckers have their own lingo. Also saw "co-driver". smart-trucking.com/team-truck-driving

See, for example, https://www.sciencedirect.com/science/article/pii/S2093791118301070

Whether the truck driver or the co-driver is in charge, or whether they share responsibility,I don’t know. My guess is that one of two drivers makes final decisions about who drives when.


Handyman: In India, the one who sits beside a truck driver whose responsibility is to assist the driver in driving with a proper nevigation that helps the driver keeping his driving safe is called a handyman.  While, If both are drivers having the same responsibilities and drive alternatively then they may be simply called co- drivers.

    In India, the one sitting beside the driver was popularly known as cleaner, because his duty was mainly to clean the vehicle, occupy driver's seat occasionally to be groomed into a better driver (often without a driving licence). This is specially for trucks. These days, for inter-state overnight journey high-tech buses have two drivers; and they are co-drivers. I am not sure of a globally accepted word for it.
