Why You Keep Seeing Those Car Caravans on the Turnpike

You don't notice it until you do, but it seems like every time I cruise up the turnpike, I spot them. Car caravans or Texas Road Trains as the internet calls them. When one vehicle is towing one or more junkers down the highway.

What gives?

What Are ‘Texas Road Trains’?

Turns out, it's not some roadside circus, it’s a full-blown cross-border economy.

These very OSHA-questionable caravans are hauling what the U.S. has deemed too old, too busted, or just too junky, and towing it south to give it a second life in Mexico or Central America.

In Tornillo, Texas, where fewer than 2,000 people live, the streets are jammed with these junk-bound parades ever since a new border crossing opened in 2016.

Online chatter across forums reveals a multitude of motives.

Online Theories and First-Hand Sightings

On r/oklahoma, one driver notes that “They pick them up at auctions and haul them south… Mexico it is!”

Over on Reddit’s r/Whatisthis, a Texan explains, “They’re buying them cheap and hauling ’em south to Mexico to fix and resell… even the first one doesn’t have a driver”.

Yes, it’s that informal.

Beyond Mexico: The Caravan Trail South

Beyond Mexico, some of these car caravans head farther into Central America, and the story gets even more fascinating.

A report from KJZZ in Phoenix describes how drivers begin in Texas and wind their way through Mexico with junk cars, bikes, recycled parts, even clothing, all destined to be repaired and sold across Guatemala.

It may sound like a ragtag enterprise, but for communities down south, it sustains livelihoods. It’s thrift meets necessity, plus a touch of car export hustle.

Sure, some speculate about money laundering or drug routes—but most evidence points to an informal trade: haul a junker, fix it cheaply, resell it.
