Tommy and Joe were not hurt -- but according to reports, three other people involved in the accident suffered serious injuries. There were no fatalities.
According to reports, four vehicles -- including Chauvin and LaFont's -- had come to a stop for a flagman directing traffic around a construction site on the highway.
Everything was hunky dory -- until a fifth vehicle (a giant tractor-trailer) came careening along and smashed into the back of another truck waiting in line.
The accident caused a massive pile-up -- but the biggest casualty ... a bunch of "Swamp People" merch that spilled out of Tommy and Joe's truck ... and scattered across the highway.
