I drive a lorry for a living, A lorry is a motor vehicle designed to transport cargo.
Wow that's interesting, do you need a degree to do that?
Trucks vary greatly in size, power, and configuration. But no you just have to go to truck school.
That's fascinating, what kind of cargo do they usually transport?
Well mine is configured to mount specialized equipment like cement mixers and stuff.
Oh that sounds like expensive products, certainly need to be careful transporting that kind of stuff.
Trucks and cars share their ancestory with  the steam-powered "fardier" Nicolas-Joseph Cugnot built in 1769.
