Are there trucks in Lord of the Rings?

Answer 1

In Book 6, Chapter 8, The Scouring of the Shire, Tom Cotton says that: Paladin Took, Peregrin's (Pippin's) father, Thain of the Shire, had no truck with Lotho Sackville-Baggins. The idiom: 'have no truck with' means: To reject or to have nothing to do with. It comes from an early French word troque, which meant 'an exchange or barter' then in Middle English the word changed to truke. Some time later the word changed further into the modern truck.

Another possible answer for you comes from the movies. Only in the theatrical release of The Fellowship of the Ring, there was a bit of a modern car with lots of dust kicking up to the right of the screen just after Sam stops to say 'If I take one more step, it will be the farthest away from home I've ever been.' The car, but not the dust, were digitally removed from subsequent releases of the movie.

So, I guess the answer to your question is: Truck, no. Car yes.
