What's the word for a group of trucks following eachother

I noticed any time I am in Chicago with that stupid 55 mile per hour speed limit for trucks on the interstate all of the trucks are lined up like a long train.

 

A lot of drivers tailgate, 4-wheelies and big rigs.

Bugs the heck out of me, because there is no good reason to do it.

 

Name of a large group of trucks following each other: Clusterf#ck.

 

Trucks running side by side ?....that's called a roadblock.

 

I’m no truck driver but that sounds like:
1. What you see right before a scary crash.
2. A cool drift (but still stuntman scary)

 

The bird took my answer. He lives in the town I went to college in. Air Force nearly beat Michigan.

The OOIDA company started out because two own operators drove side by side down the road and blocked traffic to make a political point. As such it is protected free speech and not governed the same way other traffic jams are. Most of the time though driving close to another truck and trying to past them when both are up against a 62 mile per hour governor is just a waste of time. Relax, stay safe, retire early, and live long enough to spend your kids inheritence. All this rushing around never gets you any place but in a ditch or stretched out in a pine box.
