Originele tekst - Engels - Over-the-road trucking

Ian, have you ever seen this expression before?

No I haven't. It seems completely redundant, because all trucking is obviously done over the roads...
Maybe it just means "overland shipping," i.e. not by sea or air?

Well whaddaya know! I asked Lord Google about it, and apparently it's so common that they even have an abbreviation for it: OTR trucking!

My goodness -- even IanMegill2 doesn't know everything!

So what does it mean? Is it just trucking?

Aha! I found a website with definitive answers! Apparently it's long-distance or long-haul trucking.

Oops! Iepurica, I forgot to cc you on my post above.
